When you take a shot you might see a color shifting across all cameras. Here are a few reasons why this can happen
- Set a White Balance value. If you leave White Balance on “Auto”, you’re very likely to get color variations
- Set a Picture Style value. Don’t leave this on Auto. I usually set it to “Portrait”
- Make sure you have the same lens model on all cameras. We know that the EF-S18-55mm f/3.5-5.6 IS II and the EF-S18-55mm f/3.5-5.6 IS STM are pretty much the same lenses. But the II one gives a more blueish tint than the STM version
