Man this is such an awesome technique! Definitely a lot of patience involved to get a good looking shot, BUT I think the journey is more important than the destination.
If your digital camera has a multiple exposure mode, this can work straight out of camera (with a tripod of course). Use manual mode for consistent exposure and just take three exposures for each color filter. I tried it with a Nikon D7000 (w/ Auto Gain set to OFF, exposure count set to 3) and it works great.
Is there a way to do the compositing steps with Affinity Photo (iPad)? I have an entirely mobile set up now, and Photoshop for iPad doesn’t let me copy-paste into channels as you have done here. I appreciate any help you or community has for doing this in alternative software (Affinity Photo for iPad), thank you.
I'm not sure since I've never used Affinity but the alternate way of doing this is to set each photo as it's own layer and tint each layer so that it's the corresponding color rather than black and white (i.e. change white to red, green, and blue respectively) Then you can mess around with the blend mode of the top two layers. I'm not sure what will work in Affinity, but the Linear Dodge (Add) blend mode is the one that works in Photoshop. If you can find the equivalent blend mode, that should do the trick.
I have no question on the technique, but about the first cam you used. I got a problem with the filmcounter in the back. You know something about that? The film advances but the number dial doesnt.
