Photoshop Q: how to save with no extra compression?

[hessian]

Hi,

brand new to these boards and a brand new camera owner of a Canon G5.

I like to use photoshop CS for all my image editing and I am curious what type of settings most people use for saving JPG images.

I would like to save all my photos from my Camera to my PC without any further compression.

Can this just be achieved by saving the pictures with MAXIMUM settings or is there a better way to do this that I might be missing?

When I import a photo in photoshop and hit *SAVE AS* and select JPG I then can choose my quality settings 1-10.

Now my question is what setting do I choose in order to ensure my image is not going to be compressed more than it already is...plus I don't want to choose a setting thats *overdoing* it and saving more than what I really need to.

Anyone with some advice?

I have my settings on my camera set to resolution Large 2592x1944 and Superfine compression.

thanks again. great board.

If you want to work on your files and save them without any quality loss you can chose the .tiff format instead of jpeg. The tiff format will not degrade the qulaity of the image regardless of what you do to it because of compression. The downside is the files can be large. I personally use jepg format and save the files as a level 12 jpeg which I believe gives me some margin to work on the file and save it again without any noticable loss in quality. When I am ready to send them to the printing house I save them as level 10 jpeg's at 300 dpi. This makes them a more reasonable size. Good luck,
Dennis

Every time you save and resave a jpg file you degrade the image some. When I work on jpg images in Photoshop and make changes to that image I save it as a LZW compressed tif file, lossless compression.

Never touch your original JPG... it's your negative. And do not work on JPGs in Photoshop: there's a reason you bought Photoshop and JPG isn't it.

Bring your JPG into Photoshop, save as a PSD, and work on it as much as you want, as many times as you want -- it's lossless. If you want to print, send PSD to the output center -- or TIF or JPG if you must.

For web posting or emailing, save as JPG (in reduced size normally) at a setting of about 8.

If you're worried about hard-disk space, you can delete PSDs that didn't require a lot of time-consuming enhancement.
