Hi, I'm new on here but stumbled across this forum when trying to find a solution to my problem (sorry for the lengthy explanation!).... Yesterday I noticed that in Photoshop, a PSD file I had been working on and proofing out to a client over the past few weeks had suddenly changed. There was an image of a 'note' with shading just inside the edges plus drop shadow applied which had all of a sudden lost its definition and the shading on the note itself had disappeared! So particular edges on the note appeared to just blend into the white background (it is a white note). I checked the JPG files that I had saved out and sent to the client for proofing and these were all fine (still had shading on note). Just every PSD file I had saved (I save as different versions whenever the client makes amends) had been altered and I have absolutely no idea how or why as I haven't adjusted these! Then, I noticed in InDesign today, that instances of tints had also been altered on various files - even those dating back a month or so ago. For instance a black box tinted (not transparency) back to 15% grey had disappeared - it had almost faded from view completely whereas before it was fine. Other items on InDesign files had also had their tints knocked back considerably. I am really concerned about this as I feel I'm working a bit blind not knowing how any tints or shades will print or display to others. And will produce different results. Has anyone come across this before? It seems very unusual to me - and the only thing I can think of is perhaps an Adobe update that has screwed with the settings? I did receive an update over last weekend but I think that was just for Acrobat! Which is also showing the problem. The problem doesn't seem to be affecting Illustrator at the moment - but is affecting Photoshop, InDesign and also Acrobat where pdf files that are months old are displaying tints incorrectly. I am on Windows Vista by the way! I am totally confused and this doesn't make sense....please can anyone help?! :icon_confused: Diane.
