I have a DSLR modified to take infrared. My workflow was to open Nikon NEX for color correction on an external version of Maverick; I save those modified files onto my main HD (which runs the current version of the OS) and later work on them with PS. I haven't used my infrared in about 6 months but now when I run my workflow the color corrections I made will not open in PS or LR, instead, the unmodified version will open. When I open the image in Preview or through Photos, the corrections I made are visible.
What can I do?
Please check is there any updated pending for both Photoshop and Lightroom also, you may try and recreate their preference file and check if that helps.
Also, calibrate the monitor profile back to defaults.
