Hi, I have been using photoshop and Adobe Camera Raw for many years and Creative Cloud since its inception. My saved jpg photos have been greater than 10mb for years but recently all photos I have edited in Adobe Camera Raw, opened in photoshop and saved as jpgs are no bigger than 500kb. I have spent hours online trying to find out why and have tried all of the suggestions but nothing will remedy the problem. I am seriously considering switching from Adobe unless a solution can be supplied. I have even gone back to old photos which I had saved as 15mb images using photoshop and now it's impossible. Please can anyone help.
You're mixing up resolution and file size. Those two are very different things.
The jpeg file format uses very aggressive data compression to reduce file size on disk. It normally shrinks a file down to 1-10 % of native uncompressed size. This has nothing to do with resolution. The size reduction depends on compression level, but notably it also depends on image content, by a factor of up to 10x or more.
The point is that jpeg file size says almost nothing about resolution.
This dramatic size reduction comes at a price. Jpeg compression is destructive, non-reversible and cumulative. A jpeg should be treated as one-off final delivery when bandwidth is a limitation (such as for web).
