Hello,

I'm back to entering again and have a surefire 6+ free study entry...hahahah...

I don't know if I forgot or if I ever knew how...but...if I have an image that I crop to my liking and convert to jpeg and the size is say 450kb at the highest pixel size allowed on dp.... What is the best way to get to the 300kb size with the least loss of quality?

Is it simply to keep reducing the image size ? Or is there some other way?

And after that is done, is there anything I can do to get some of the quality back?

Thanks

adjust the Jpeg quality downward until it come under the limit, no change in size is needed.

I find this very helpful.

Change file size from 150 to 300
Change Dimensions to 800 pixels max

save-for-web and optimize for file size

Open up the photo you have that's above 300kb and do like 21_F.gif cpanaioti said, save-for-web. Rename the photo for entry purposes (example: ABC.jpg, save-for-web as ABC_web.jpg). Optimize photo to 300kb and click ok. Then when PS ask you do you want to save the changes to the original click no. You will have two files now; the original ABC.jpg with it's original quality and the new ABC_web.jpg that you can enter. Hope this helps.

Thanks...I'm going to try these suggestions. I'll let you know if I see a change.

LOL !!! Much better ! It didn't stand a chance before the conversion help! The way I was doing it was obscene! It really took quality out. Now it is nearly like my huge photoshop file.

Thanks for the 6+ Free Study.

I like to save well below the 300kb size and apply usm one more time, which drives up the size a bit, but gets rid of the blur reducing the size imparts.

This doesn't make any sense. First you resize, then you do whatever is your final output sharpening, if any, then save-for-web and specify 300kb, and it will save at the highest possible quality that does not exceed 300kb. It couldn't be simpler. There's NO need to save before doing output sharpening and then save again, that doesn't accomplish anything.

Bear is right If fact, it will make it worse. Each time you save as a jpg you lose image data..
