First of all, Wish everyone a happy diwali & a prosperous new year. May the new year bring lots of happiness and prosperity.
I wanted to come up with a quick 30 mins experiment to test the concept. Ofcourse it has to be quick - it was wed and that is just half way through the week. Gosh!
Anyway, I took the help of my favorite old blue comforter for setting up the screen. That was the closest I had to resemble blue. The main problem I had was it was very light blue and if I did it in flash it will come as almost white. I set that up on the door so that I can turn the screen diagonally to get more distance for shooting the subject.
Krupa was already sleeping so my subject was either some neighbor but given it was 11.30PM I thought it would better be me. I setup the camera on 10 seconds mode with continous 8 snaps on a tripod. The comforter was resulting in a greyish blue due to the lighting and I just used that for my snaps. I found a suitable set of pictures in less than 15 mins.
My earlier research told me that Photo Key 3 is simple and best for my needs. So, i installed that and ran my pictures through it. It took me few minutes to figure out how to set the key color, tolerance, shrink, expand, and then export. To my amazement I had my chroma keyed picture with a taj mahal background in less than 25 mins. And that was the first time experiment.
Today, I got a decent color blue king size bedseet from CH Martin for 8 bucks. yeah, 7.5 ft x 7.5 ft blue sheet for 8 bucks. I set it up on the floor for my battery tester picture. Took a couple of shots with flash and ran these through Photo Key 3 in batch mode with few threshold changes. And, to my amazement the blue was completely gone. I imagine now how it would be with proper lighting. Attached is one picture from today's experiment too.
This seems like a easy but a very powerful technique to take snaps which can work on any background.
More updates later.
Cheers,
rash driver
