Hi Folks I picked up a used Canon 6D (1st version) and downloaded Canon's DPP 4 RAW processor. The software converts the files to TIF alright but none of the sliders like brightness or contrast adjustments do anything. I can move them but they don't affect the image at all. So far the first shots have come out fine though and have needed little to no adjustment in photoshop. Doing a search I see some complaints about DPP 4 from 2014 and wonder to what degree things were resolved by Canon. I'm on OS Mac Mojave 10.14.6 and have been successful so far hanging onto and using CS4 photoshop. I had been using CS4 to convert the RAW files from my 5D classic with 'Camera RAW 5.0', make adjustments there, with final tweaks after converting to TIF. Am I missing anything just using DPP 4 only to convert the files to TIF, or should it be fully operable for adjustments? 'Camera RAW' 5.0 in CS4 offers quite a lot of nuance and flexibility for 5D RAW files, but it's unusable with the 6D.
