Will losing weight in pictures affect the washout effect?

Yes.

Generally, the photos taken by digital photos are in JPG format and have been compressed. Judging from the size of your photos, it is a simple 8-megapixel camera, and the photos taken can be developed into an A4-sized photo. If you don’t want to make it so big, you can change the size to a smaller size, but you can’t change the resolution. (This involves knowledge about bitmaps, which is quite troublesome. I personally suggest you take a look at /macklinkkk/blog/item/5243de09810d90276b60fbab.html Here we talk about the difference between bitmaps and vector graphics) General ACDSEE and photoshop can convert them.
