About the Image(s)

Last week we visited our grandchildren in Idaho Falls Idaho. I took this image of the Upper Falls on a river near the Grand Tetons mountain range. I took the image with my cell phone and had to do a little photoshopping to make the active falls look OK. If you look real close at the far left edge of the snow drift on the other side of the river you can see a little white dot. The dot was a crashed drone that someone was using to photograph the falls. I guess the drone crashed and there was no way to retrieve it.

nice attempt, very challenging to get moving water in cha-cha stereo image.   Posted: 06/04/2021 16:36:42

The secret to catching falling water in cha-cha is to use a smaller aperture and longer exposure so you catch the 'rush' of water rather than a 'splash' on each frame. The longer your exposure, the better they will match.   Posted: 06/10/2021 23:47:45

David, I think you did very well using your cell phone. The image has a good depth of field. The sky helps make the image. Having the look-out in the foreground also helps.
Sorry, I don't see the little whit dot.   Posted: 06/11/2021 11:17:09

The white dot is real small so here is a 3D portion of the snow drift with the drone on the lower left. We looked at the drone with binoculars and one of the props was damaged and it looked like a real good drone.   Posted: 06/11/2021 15:51:41

Good stereo of the waterfall and again interesting what can be achieved with a mobile phone and a well chosen viewpoint   Posted: 06/17/2021 11:51:07

Here's how I fixed the waterfall. In photoshop, I made a layer of just the right falls and placed it over the falls in the left image. If I left it that way, in 3D, the falls would have been like a flat "cardboard cut out" setting in the water fall. In photoshop, I moved left or right all the edge of the new layer with the "warp" tool to make the water match the edge (in depth) of the water in the original image of the left view. I then warped the inner parts of the new layer and moved some parts of the water fall left to make it come closer and moved other parts of the water fall to the right to make it go back in the falls. It took a few go-arounds and what you see is the result.   Posted: 06/17/2021 12:55:49

Very nice image. The water and snow aren't blown-out and the 3D effect is good with the different subjects at different distances. The exposure is perfect.

I'll bet you had a wonderful time when you saw your grandchildren! We saw our two young grandchildren last week when the family visited for the first time in 1 1/2 years. They wore us out but it was heavenly.   Posted: 06/18/2021 23:41:32

Nice stereo of water fall using Cha-cha method. The image has nice depth, color and composition. There is nice separation of near, middle and far objects. Thanks for explaining about the correction technique in waterfall.   Posted: 06/21/2021 11:28:02
