Muybridge made a bet that a running horse had all four hooves off the ground at the same time on occasion. To win this bet he had to invent a better shutter and other apparatus to capture a series of images, one of which, he hoped, would win his bet. Taken together, those series of still images somehow represented motion. Inadvertently, he invented the core concept of the motion picture, for which we all thank him.
In a way, these are heir to Muybridge.
I still haven't figured out how to get the moving objects' shadows to look natural. Things also got difficult inside the bicycle wheels.
This is really cool. I think the wheels look great. I love the overlapping. Did you take the shadows out? What happens to the shadows? Thank you for something interesting to wake up to.
The problem is that without shadows the moving objects appear to be floating in midair. Keeping the shadows is also difficult when they overlap one another and the subject areas I want to keep.
Not too many shadows in these. #1 and #3 were shot on very gray days after the sun had dropped below the buildings. I used Luminar Neo's sky substitution on both of them so they were not entirely washed out. In #2 the shadows were behind the runners. This has been a bigger problem with car sequences.
If you take a very close look at the bikers' wheels, you can see that some of the wheels have gaps due to the imprecise masking of the overlapping layer. I use Topaz's Mask AI and it had a lot of trouble where there is not enough contrast. It didn't notice the spokes. These are difficult due to the extreme magnification even with all the pixels the D850 gives me to play with.
I see what you mean about "floating in midair," but at the same time, I can understand what you meant about shadows being difficult to layer. I need to keep in mind to note the direction of the shadows because it's probably best to have them behind the subject like in the runner's photo which works because there's not as much space between the legs to even notice them. I did notice the gaps on the tires after you mentioned them and magnified them. Look forward to hearing suggestions from others.
