AV Geeks Lunch 6-20-2022

so so so so so so interesting hi everybody i'm skip alzheimer welcome to the av geeks lunchtime streaming show where we watch old 16 millimeter films and that was from a fellow collector uh filmmaker craig baldwin who's based in san francisco he just sent me a giant box of some things to scan and i was like well if i'm going to scan them why don't i um show them to you guys so that was one of my favorite genres of um home movies which is uh what i call the kodachrome halloween parade um that was a thing is everybody is is dancing and having a good time then there's this parade multiple times past someone with a camera uh this happens a lot in school uh at elementary schools but uh it's glorious and given the caliber of the costumes i think all of those were homemade and i think that these were maybe art students uh definitely in college uh they definitely seemed to have a maturity to them um and there wasn't i think the only person the person with the straw hat was the one that was kind of seemed like they phoned it in but um you know as always with uh many early halloween uh parades there's some cultural pro appropriation um some people uh in what we call yellow face uh maybe a person in blackface i don't know um but anyways uh that's unfortunately that's part of the trying to grasp other cultures and not really understanding them but i still love it still love it anyways uh so we watch like i said old 16 millimeter films and so let's go ahead and watch let me see one two three um about our friend water as people and animals we climb them when we were young we walk among them now painting trees and when our end comes we may have our final rest under them we may even share their beauty by becoming one with them [Music] [Music] good evening i am elliot o'hara starting on a country-wide sketching trip and inviting you who share my love for trees to join me you'll find the kamani tree and the royal palm in hawaii the saber or silk cotton in florida spanish moss in georgia or an old cottonwood in tucson we visit key west for coconut trees and the state of maine for this wild cherry pictures can be realistic or abstract but before dealing with planes like this or rhythm or selective color we should go back to three fundamentals a possible symbol for the tree the structure of trunk and branches and the character of the foliage we'll start with this old elm in chagrin falls ohio the elm has a definite structure and the artist ever on the watch for symbols can easily notice that all of the limbs branch out to make the letter y this is more apparent in the winter when we can see that the smaller branches repeat the same motif let us use this symbol then in painting the elm if new smaller y's are added on top of each larger one the result will have to be an elm tree finding a symbol for it is the first step towards capturing the personality of any tree in the winter when branches are bare the sides of the y are steep but add several tons of leaves and the y widens causing the tree to mushroom out and to have a greater spread trees are not flat like printed wise but have branches that reach towards us in a way like these hands since light outdoors falls from above we see the dark underside of the branches that incline towards us but those on the far side show their light topsides we make this one come towards us also that one the others by contrast will naturally seem to recede in the bright sunlight of summer the trunk will have a light and a dark side i'm double loading the brush putting the light color for the sunlit part on one side and the dark shadow color on the other the simpler the description the better it is with this kind of stroke that i propose to paint the y symbols i'll do them as actual tree trunks and branches the brush held diagonally makes the smaller branches a shadow of a branch on the trunk there are leaves they make a screen against the sky we can achieve this effect by smearing with the flat of the brush rather than by stroking the paint remains only on the highest part of the paper's granular surface the shadow side will be darker as well as the under parts of the leaf masses but should look warmer than this paint did on the palette two brushes on the same handle save time they don't come that way but it's easy to pull out the stick and combine them they also take less space in the box twigs and small branches should go in while the foliage is still wet they should moreover be seen in the breaks of sky those which occur under the umbrella of leaves will naturally be dark darker here and very dark underneath now let us explore further the symbols for various trees the maple like the elm has a symbol the letter u steeper at the top but wider below so that the branch tips can stretch out to the vital sunlight these trees were found in north conway new hampshire the lombardy poplar it reaches for the sky and the artist's hand should feel the upwardness of the strokes as if drawing long stemmed l's the branches of the weeping willow start in the same way but as the brush moves up it tires and like a rocket trails and swings listlessly the japanese have an amusing symbol for the pine branch it is a duck's leg let that be the duck and this the leg with its webbed feet the pine trunk now replaces the duck and we have only to add needles at the tip like analogies in writing symbols in painting serve to heighten the quality the sycamore should be characterized by a sickle the same straight line with a curve on the end could serve as well for the apple or even the oak the oak is strong the hand that was listless when painting the willow must now hold the brush tightly and move with vigor there is an unexpected quality in oak twigs and branches they go their own way the cedar eucalyptus and monterey cyprus have spiral markings in their bark like strands of a frayed rope this effect may be achieved in watercolor by long sweeping strokes of a brush which has so little paint that the hairs separate and act like a lot of small brushes this cypress is in la jolla california a four timed pitchfork is shown because its structure resembles that of the mangrove this tree as you can imagine is well anchored against the thrust of wind and tide turning from symbols to foliage we find that a rough brushed area as a basis may be treated to represent foliage of various trees tag it with a few large spots and you have a catalpa the same treatment could serve for a magnolia or a banyan a horse chestnut would have the spots in groups the maple also has large leaves and an autumn they are brighter in color than those of almost any other tree a few brush marks label the character of the leaves it's great fun this putting in of dots and when a thing is fun we are likely to do too much of it so whether it is a red tree or a yellow one i advise that you use restraint while the poplar foliage is finer the same kind of rough brushing can describe it but they are being labeled with small round dots at the tips of the upswept branches this way for pine needles it is sufficient mainly to flick the brush out from the edges of the painted area an equally good method for spanish moss but here we flick downward if it is a eucalyptus tree then we may tag the clusters by narrow brush marks blossoms as well as some kinds of foliage are handled in quite a different manner the background has been painted and before it is dry i drop clear water into it these strokes i have nicknamed oozles the process blurs one clump of foliage into another just as whole trees may dissolve in the distance trees like people are gregarious as in crowds a few individuals may dominate a scene while vast numbers are blurred and lost this is the background going in now when the blossoms are dry the dark branches can be added crisply to contrast with the wet blended ozils and the distance for these canoe birches in new hampshire the background is wet blended to throw it out of focus and the trunks are taken out while the paint is still wet the knife held flatly makes a broad mark but for the finer branches its tip is used do not hold the knife as if shaving but as if spreading butter that way the excess paint forms the triangular marks that usually occur under each branch intersection aspens in colorado or miller lucas in the south can be treated in the same way the sycamore trunks turn and twist like serpents and is characteristic of them that the bark peels off leaving leopard spots of tan or gray most pine trunks have rough bark like this one at lake tahoe this old beach shows scar tissue and stumps from lost branches in painting these redwoods i used wide knife scratches to portray the vertical slabs of bark going now to the south we find entirely different sorts of trees their leaves or fronds are waxed and glossy to prevent the sap from evaporating in the tropical heat the banana is a very good example of this the trunk of the royal palm looks like cement but has annular creases these vary in thickness according to wet or dry years again the double loaded brush is used but it continually starts and stops to show these creases in the coconut bowl there are circular grooves too but they are like threads on a screw we paint them by putting on first a band of color and then a zigzag line with a small brush with certain palmettos the fronds do not drop off but are cut leaving spikes sticking out in spiral rows a possible way of painting them is with rectangular dabs and knifing but there may be better ways of portraying them i don't know what's going on there petticoat variety hold on has to be painted long twist on strokes that was really weird it will be the dark cracks very fine nesting place for rats i'm told this is the underside and these the dark cracks the royal palm does not sweep or fan outward but from the green sheath above the trunk unfurls a proud plume i think it's my favorite of all the palms in the palmetto we find a thin stalk with a fan this one is in california it may be interpreted with a double motion sidewise and outward in the actual painting of the tree it comes out in this manner coconut fronds are flexible and frequently occur on one side being more affected by the wind than those of the royal palm the top of the washingtonian palm radiates like spokes of a wheel from a center and has a circle of fans at the ends trees are of various races and they have their own personalities i've tried to help you see their qualities and i hope added to your enjoyment of them we won't say goodbye to trees they will always be here unless we destroy them they are the other half of the living world and have almost as much capacity for being loved as people and animals we climbed them when we were young we walk among them now and when our end comes we may have our final rest under them we may even share their beauty by becoming one with them [Music] so sorry for interrupting that well one i i hit the wrong button brought up the wrong film um i was supposed to bring up uh your friend uh the water clean or dirty but it brought up painting trees by elliot o'hara which is fine it's a very uh tranquil thing but in the towards the end of it there was this loud music that i heard on my end this loud dramatic music and i was like i'm scrambling to figure out where it was and like if you could hear it and which is why i then went in and apologized because i didn't know where it was coming from and why i could hear it but nobody else could that was really that went through me for a loop i guess the more stuff i pile on to this streaming show the more likely something weird like that's gonna happen so um there you go oh you know no that didn't happen all right i have no idea anyways uh this time we're going to watch your friend the water clean or dirty enjoy [Applause] hello wanna see where i came from hold your breath first stop the reservoir hold your breath again it'll only take a minute here we are mountains snow forest wouldn't you like to live up here nice clean water lots of it see that beaver see that moose they like clean water getting downstream now see those ducks those fish like clean water too let's us go fishing clean water is good for everybody [Music] ah ah that's the only kind of fish you get in this dirty water let's get away from here and see what's wrong [Music] look at that [Music] [Music] can't swim here can't even take a drink what's going to happen to those poor fish four fish uh so there's others in this series i think there's uh your friend the soil and maybe you're from the air and they all are very early films that try to talk about uh pollution um in the environment something that we certainly are talking about nowadays but somebody recognized it back then and i liked the fact that kid got shrunk down like when one when a film was animated two when they start using supernatural aspects all right um let's look out into um into space some of you might have noticed uh i've been showing a lot of encyclopedia britannica films and that is because we've been doing a big encyclopedia britannica scanning project uh where we've been going through our films uh going to tiny dark corners in our archive and pulling films and so we've been uh digitizing a bunch of stuff that we haven't seen and so um i'm happy to share them with you these freshly scanned films um so here's space probes exploring our solar system enjoy [Music] a space probe unlike an ordinary earth satellite seeks out knowledge in regions far away from the earth [Music] as shown here in this historic film of the first probe american pioneer one was launched in 1958. first it was placed in orbit about the earth then another rocket was fired the speed of the payload was to be boosted to 25000 miles per hour the speed necessary for an object to become free of the gravity of the earth no longer an earth satellite the space probe would then be free to coast to its far off destination and radio back its findings by telemetry the technique of transmitting or reading instrument recordings from a distance [Music] batteries are used to power instruments which detect and analyze various phenomena and to power radios whose antennas send the findings back to earth this is how a space probe operates to bring us new knowledge pioneer one however failed to escape the earth's gravity and fell back burning as it re-entered the earth's atmosphere in 1959 russian lunatic one and then american pioneer four were sent into space and beyond the moon lunatic ii revealed that the moon had no magnetic field the discovery was made just before the probe hit the lunar surface lunic 3 was so engineered that it curved behind the moon and took photographs of the side that had always remained hidden from the earth pioneer 5 was the first interplanetary probe it was aimed at venus and launched in the year 1960 in 1961 a venus probe was launched by russia probes failed to get information about venus both went into orbit about the sun but a new era had begun larger more powerful rockets allowed larger more sophisticated payloads so man took his first step first the russians then americans successfully orbited the earth in the early 1960s the next step will involve sending crews into space the problems solved by such a project will undoubtedly lead to landing the first men on the moon the second generation of moon probes such as this ranger have helped to prepare for such a landing by collecting and relaying back information by televising back to earth details of the moon's surface the same telemetry methods will be used for the more sophisticated moon probes such as surveyors designed to make an even more detailed study of the moon equipped with an elaborate system of solar cells the surveyor will turn sunlight into electricity to power its instruments and radio because this side of the moon always faces the earth the earth appears suspended in the moon's sky and can always be seen because there is no atmosphere clouds or haze on the moon delicate instruments whose measurements can be affected by even the presence of the spacecraft are held away from the craft by long mechanically operated arms mirrors reflect into the lenses of the television cameras a close look at the harsh irregular surface which except for meteorite impacts is believed to have remained the same for millions of years [Music] meanwhile other probes are being planned some will study the moon as they orbit around it some will explore the solar system shown here by concentric circles representing the paths of some of the planets as they orbit about the sun nearest the sun is mercury venus is next then the earth then mars because venus and mars come closer to the earth than the other planets the first probes have been in their direction there are times when venus is only 25 million miles away however at other times it can be as much as 162 million miles away mars our next nearest neighbor is sometimes as close as 35 million miles away but when the earth and mars are on opposite sides of the sun the distance is sometimes as great as 248 million miles as a result of these variations in distance space probes are launched only during those periods when the target planet is in a favorable position between 1965 and 1975 only certain years are favorable for probing venus and certain years for mars specially designed for interplanetary travel the mariner is capable of traveling great distances and descending back information gathered along the way shortly after launching solar panels unfold like butterfly's wings sensors cause the paddles to face the sun solar cells are used to convert sunlight into electric power needed for telemetry through the nearly perfect vacuum of outer space telemetry has already successfully functioned over a distance of 54 million miles radiation counters aboard the probes have revealed that the sun constantly radiates streams of electrically charged particles called the solar wind as symbolized here during a solar flare-up the radiation increases how does this affect the earth well the earth like a bar magnet is surrounded by lines of magnetic force shaped something like this space probes have proved that the earth's magnetic field controls the paths of the charged particles from the sun trapping and forcing them to circulate within the field some escape to form the earth's aurora borealis some escape back into space but the dense accumulation that remains is called the magnetosphere and is symbolized here by this model the magnetosphere is now known to be very dangerous to space travelers space probes have also discovered new facts about the planet venus a surface temperature of 800 degrees fahrenheit which would prevent life such as exists on earth venus like the moon rotates very slowly probes have found no magnetic field but because there is a strong magnetic field around the fast spinning earth many scientists now conclude that a magnetic field is caused when a celestial body rotates rapidly future probes will undoubtedly provide the answer space probes are mechanical scouts reckon ordering man's new frontier already they have warned him of the magnetosphere and its deadly radiation of the searing death that lurks beneath the clouds of venus as the earthling learns to become a space man he must ask himself many questions can i survive out there what will i learn what contribution can i make with this new knowledge [Laughter] man that narrator sounds so much like that moody institute of science narrator who uh we did the how many stars um i need to do some comparisons because yeah and also uh good ears to somebody who uh heard the music in the background and recognized it as some library music that was also used in um an idol living dead it was also used in a fallout fallout film made by the civil defense um and that's what made me realize like oh that's just library music they didn't actually write it for um uh what am i trying to say they didn't write it for the film they didn't have a budget for that okay so we have another film set up on the uh sintel the film scanner and let me just say uh thanks for watching us and if you like what you saw you can buy some coffee at ko-fi.com av geeks you can also go to avgeeks.com and buy dvds we have over 180 dvds for sale it's kind of crazy and uh coming soon i'm trying to figure out what i'm going to do with this but we got new stickers new stickers um the artwork provided by one of the homeschool kids steven um and so i asked his permission if i could uh make a sticker i'm gonna send him a bunch of stickers um but yeah so that's gonna be coming up at some point all right uh so uh on the sintel um this is a film made by the un in the titles clip but it's world without end enjoy oops all right nope let's try that again there we go enjoy [Music] so [Music] [Applause] [Music] [Applause] [Music] we are looking at human beings and we are seeing something of two countries where they live in the west mexico in the east thailand or siam as many people still call it different languages different religions different animals trees and flowers yet in both places people get their living from the earth and from the water in both places people feel pain and hunger and people enjoy health and the good things of life they have enemies and they have friends they have children and their children to be happy this man's name is faustina he is a taraskin indian his country is mexico [Music] he is a fisherman who lives on an island in lake patswara long ago before any european came to the americas this lake was the center of the great terrascan empire the teresque and indians still live here they have lost their empire but they still get their living from the lake and they retain their old love for music and for singing [Music] [Music] [Music] you [Music] [Music] [Music] [Music] oh god have come into the town from the islands where they live from the settlements along the lake shore and from the villages in the mountains around the lake this is a social occasion as well as the occasion for buying and selling [Music] there are processions to be enjoyed and all the noise too it's like an old-fashioned revolution an old-fashioned revolution [Music] here also is something which is in its own way like a revolution the people in the launch are students who belong to an organization called crefar crevall means the fundamental education center in latin america it is supported by unesco and by the government [Music] and because of people like this if there were enough of them the world itself could be better the students of trafal many more of them than we have seen so far when they have finished their course are going to return to their own countries in latin america where they will try to apply the knowledge of life and the sympathy with living people which has come to them partly by nature and partly by study and experience the director of lucas ortiz has faith in them and knows the greatness of their task here we leave you on the path of your destiny and that of the americans you are carrying on a gigantic program of work but you are not dwarves you have to confront disease with health poverty with abundance ignorance with knowledge hate with brotherhood war with peace [Music] at the headquarters of the united nations in new york there are more flags than those of latin america and many more countries are represented than mexico and cyan it is an organization which was formed because people were ashamed of the past and because they had hopes for the future for a long time the peoples of the world have been organizing their fears and their hatreds this is something different [Music] and though no organization is perfect no plans can be guaranteed to be successful we do know enough to know this love can cast out fear and as we have seen it is not impossible to love your neighbor now as the world shrinks the neighbors are closer together moreno the student and the man on the elephant the fisherman and the farmer the children happy or unhappy are not so far apart and though we may not all have learned to accept this fact it is a fact that we all live in the same world with them and with others [Music] it was 1953 um i think uh the korean conflict was going on u.n was trying to spread its message about trying to help some of these populations that were having some problems but um yeah it's fascinating to kind of look at that um i do have some other un films that are longer um that are kind of interesting uh that kind of talk about specific aspects of um you know global issues like uh air traffic um you know since we're going from one country to another how do you maintain that is there who's the governing body that governs that and there was the u.n branch that did that i can't remember the name of it but um at some point i might dig that up it's kind of interesting um so thanks for tuning in today i know i'm ending a little early today sometimes that happens um but i appreciate your eyeballs appreciate you watching and commenting as always you can uh donate coffee to us but you can also a free thing you can do is just hit the thumbs up button or the like button uh or the subscribe button those are great ways to say that you enjoy what we do or you at least are intrigued by what we do you don't necessarily like what we do um but you appreciate the fact that we do it um we'll be back again tomorrow on tuesday and we'll watch some more 16 uh and maybe some more from the uh craig baldwin collection this also i should say that this last film was from his collection as well sent me this big solid box of films on cores and so we've been going through those and scanning them everybody have a great rest of your day and we will talk to you soon take care you
