Cinemagraphs for Outdoor Photography
I don't know how many of you have heard of cinema graphs, but what a cinema graph is it's a still image that has an element in it that moves and it's essentially you take a video clip and you can do this with your iphone or whatever I mean it's a it's a video clip you know your your smartphone so notice that the people are walking around up the top that the water is only running in one spot and when it goes into the water, it disappears. This is if the water's frozen and that's a cinema graph it's kind of fun so here's a little segment for you you start to realize that nothing's going by on the other ages now the roads not going anywhere but the outer edges it just great fun. Um this was done with a piece of software called flicks als oh, in here, it's much easier to photograph water that doesn't move goto bouchard gardens by victoria um my colleague jerrold belene in there and he's just stands there in the water does the moving so this is the software that makes it all happen? It's ca...
lled flexible dot com and it has like a mask and what I've done is here on that gator I just took the area this area continues to move and everything that's in the mask is now frozen and you take that this is a video clip that's down below. You have only a certain length of time now you khun this is software isn't that cheap, but at the same time you can sometimes find it on sale for its quite inexpensive. But you can do this and photoshopped or in after what is it aftereffect? Was it after aftereffect? You can also do it in there there's all kinds of tutorials online. Just remember the name cinema graph and it's a whole if you go online in and you and you, there are web sites that just have one of these after another where there's a picture of a model and she'd be sitting there and her coffee will be steaming but nothing else will be moving or the window of curtains will be moving with the wind, but nothing else moves in the picture it's quite interesting to do that, but what the one with the car is the one that I like the bones I'm going to do a little bit more work on that. I have some ideas to make that even crazier than this, so we have time for a few questions sounds good, george, and let us know if you have any in the studio audience some of these questions go back to the beginning of this segment, so let's see you were talking about cross polarization group, and the question was, are there particular shutter speeds that are needed when you're using when you're doing that technique? No, because you're having to throw in a lot of flash simply because you're losing five stops of light, so if you're on a tripod and so forth, you couldn't do a long exposure when I did the big paintings and I had a big four by five u camera and two huge flashes, I would have to flash the flashes like three times in order to get enough light to light up this big painting to get rid of those reflections, so the exposure is whatever it takes to get a good image so there's nothing in particular that is important here other than getting a good image getting a good exposure, I thought I saw a hand over there. Okay, so this question was about the order of the tele converters or extensions? Does it matter if the one point four x is closest to the camera or the two x? Is there a particular way that you have to add those on there's a particular way that they will fit one will fit into the other? And I cannot remember when I'm there I what when it doesn't work that's not the right way he flipped him over now it does work if you have that twelve millimeter extension tube that you put in between the two you can go either direction, but no, it doesn't make any difference. You've got a five hundred millimeter lens, you put it to exxon, it that makes it a thousand then you put the one point four on and makes it fourteen hundred. If you go the other direction, you still end up with the fourteen hundred at the end, so it really doesn't make any difference it's how they fit and that the version twos of the cannon converters will make like I said, version one will not version three will not, but version to will, and if you mix and match them, you're just going to have to keep one of those twelve million or tubes around in order to figure out where which place you have to put them, but it will work. I have a question about the size of your image files when you're doing the focus decking, um, it's a two questions really is how do you manage the huge files on your computer and backups? And do you keep the original files once you've created the stacked image? Or do you get rid of those? Ok, the good thing about stacking is when you're done it's the size of one image. Because it all compresses back down and becomes one image while you're working with that, you may have a whole bunch of images. I did a number of big stacking images when I was testing this five gs five years, our camera and the fifty megapixels each and twenty, thirty pictures, I ended up going to jay pegs at some point when you're working with roz, you have sixteen bit files there, twice the size that you would normally have. There were four hundred megabytes each and yes, that becomes a big factor, but I put them together on my laptop, so obviously it's not too difficult to do when I'm working on them in my office like that thousand images, I do it in segments, I'll do this image and then I'll add maybe that image to it, and I'll do it piece by piece until it bills and try to keep from trying to put everything through all of the same time that becomes very, very difficult. I save everything on external drives, I use the apple that little trash can mac pro, so there are no hard drives built into it, so everything is on hard drives. I buy my hard drives from costco, which are sea gates and lately, five terabytes for like, one hundred thirty some dollars I have thirty six terabytes of drives at the moment and then thirty six terabytes of backup drives and thirty six terabytes of drives at the bank in the vault. So the fact that they're this space getting cheaper and cheaper, it means I don't worry too much about how big the files are the computer can pretty much handling a normal computer could do most everything we're talking about here that one thousand four hundred four thousand images or one thousand four hundred images that gets a little crazy. And now that I'm working on now that I'm working with this fifty megapixel camera, things move a little slower, but at the same time, it's, you just have to have a little patience. I can remember when an eighteen megabyte file from a cd rahm that kodak would make took forty five minutes to load. I still remember that happening. Uh uh, that was only eighteen megabytes. Thanks for question. Oh, go ahead from mike. Yeah, george. Before, when you were showing the images using stacked tell the extenders. You know, the two and the one point four and all that you mentioned a number of techniques that you use to get sharp images, I noticed you. Didn't mention image stabilization on the lens? Does it ever get to the point where that's useful because usually you would turn that off when you have a camera on a tripod? But when you're getting, you know, thirty two hundred millimeters or something like that in the wind blows does turning on image stabilization help at all? Or does it complicate the problem? It can that that's that's a good, good thought and at some points it's a good idea? Because if there's any wind or anything like that, I mean, either you can't work at all or if you put image stabilization, you will see sometimes that if there's a movement in that tripod that it works fine, there are some lenses that if you lock it down and you put on image stabilization, the machine gets of the lens starts to get confused and it starts to move the back element around and it's a ziff there was movement, so most often I'll turn that off. Now if you're working on the tribe by any and you have to touch the tripod to the camera and you're working with the tele converter, maybe one tell a converter or something like that I would leave it on because there is movement that's happening there and image stabilization is not dependent upon what f stop you're using, whereas auto focus is so there are times when it makes sense. And there times when you better not if you're using one of the older lenses. Most likely, that image stabilization is not a good idea. If you're locked down on a tripod, many of the new lenses, it doesn't matter.
