When Color Matters - EOS 5D Mark IV vs iPhone

[rs-eos]

I recently picked up a LEE Filters swatchbook so I could narrow down what gels to purchase.  As I didn't want to dismantle it, figured I'd take some images and create a collage.  Thinking nothing about it, I took the images with my iPhone.  However, in looking at the images, I had to just laugh.  It effecitively made all the blue gels around the same color.

So decided to do things correctly and set up my EOS 5D IV with EF 135mm f/2 lens on a tripod with the lens pointing straight down.  Manual mode, f/2.8, 1/200 s, ISO 100 and flash (Profoto B10X Plus) set to manual mode at 6.5 power (3.5 stops lower than full; probably would have been the equivalent of a 600-EX-RT at around 3/4 power).  Kelvin set to a fixed value.

First image is of the 7 gels with an iPhone 15 Pro (color shifts are readily apparent; see the white background):

Here was the setup with the 5D IV:

I like the extension. I could make one out of a strip of metal, drill and tap. Thanks for the idea.

Nice setup, I like it.
