Suddenly the smallest brush size is too big

[henrikr30486962]

Hi, I have a super weird problem.

I opened up a file to continue work on it today, and suddenly found that the even the smallest brush size is fatter than all previously drawn lines. I attached a picture to illustrate. The bottom line was drawn days ago using a size 3 brush, and the top one was drawn today using a size 1 brush. The old one also somehow looks more blurry?

I've never used any other brush than the standard one in Photoshop. I've tried resetting all tools, but it didn't change anything.

I suspect something may have happened when I tried to double the canvas size the other day. Halfway through, I got an error message saying the scratch disk was full, so I cancelled the process.

Is there a way to make the brush work like before?

Show us a screen shot of your entire workspace.  That will give us an idea about your image resolution/size, and what zoom ratio you are viewing at.   

Or just tell us the size of the image in pixels, and confirm you are viewing at actual pixel size with zoom ratio 100%

I can't edit or close the thread, but I will say that I ended up restoring a previous version of the file from Dropbox. Looking at the settings side by side, I couldn't find any notable differences. Not in zoom ratio, file size, resolution, canvas size or image size.

This would happen if the pixel dimension of the file changed.
