When I opened the file it was 2.3 megs, before opening and 14 Megs after opening in Photoshop. I made an adjustment using levels and then file > save. I then rechecked it and it was still 2.3 megs. The file should not change enough for you to see in regards to the compressed size, if all your doing is a levels adjustment.
I never use the file save as jpg, unless I am sending the file over the Internet and need to get it down to a size that can be downloaded in a reasonable amount of time.
I always change all my jpg files to tif files the first time I open them to prevent the small amount of deterioration to the image, which will happens each time a jpg file is opened and closed. |
