Re: New camera-have question on Adobe Photoshop Elements

Excuse the newbie question.
I have a new Sony W90 digital camera as a low cost way to get into
digital photo just for fun. Nice camera for the price.

It saves pics as JPG's. There is no option to save as RAW or TIFF on
the camera.

If I bring the picture into Photoshop ELEMENTS and save it after some
changes I made, I resave it under a different name with a save jpg
quality of 12 (which I believe could mean no compression). There is no
save choice for no compression.

I noticed that the file size actually increase from 94kb (sample image
on PC, not a print quality photo) to 127k when I save the file under a
different name.

I assume that Adobe is adding some data to it and that increases the
file size.
1***Any thoughts?

I would then normally take the JPG picture (not the one described
above) to CVS, Eckerds, Wolf/Ritz, or send it online for printing.


****2. Not sure what other formats the chain stores or online photo
places accept beside JPG??


Thank you very much for this basic question.

When you take a picture with your Sony W 90, the camera software compresses the image when it converts it to .jpg format.
When Photoshop Elements opens the .jpg image, it uncompresses the file, and converts it to .psd format.
When you SAVE the image after manipulating it, Elements compresses it again. If you choose Quality level 12, that is not uncompressed but only slightly compressed. The extent to which Elements compressed the file was less than Sony compressed it in the first place, thus the larger file size from Elements.
However the image quality right out of the camera is as good a quality as you can get with that image.
Using Level 12 does not improve the quality over the original. If you want to preserve the image quality that you have, because you may want to do some more editing later, you shold SAVE the image in .psd (Adobe's lossless compression format) or .tiff which is also a lossless format.
