My Photoshop 2018 has suddenly started drastically shrinking the size/quality/resultion of files as I edit them. How can I fix this? Was there a recent update that caused this? It happens even if I tell it to save it with the highest resultion. Very frustrating
Please explain what you mean, and give us some example numbers. There are no updates that would cause this to happen. What kind of edits are you making and what are you looking at to determine your numbers.
Cropping and adding layers. I've been doing the same types of edits for years. Typically my pictures are about 9 or 10 MB to start. After editing (cropping, adding layers, adjusting light levels and Autosmart tone) they shrink to between 3 and 6 MB. Now I am doing the same sorts of edits and they end up at 800 or 900 kb and they don't look as nice.
I was able to trace it down to the croppping step. When I crop now it shrinks the file size greatly. Seems like the pixels/inch setting got decreased to 200 for some reason. I increased it to 300 and that has helped, though I still feel it's shrinking the file too much after cropping.
