When I save my RAW files to a JPEG I can choose from 1-12 for the quality. If I pick MAXIMUM it goes to 10. So what is the benefit of saving it on 12?

I think everyone will tell you, save to tiff, it is lossless.Then do your editing and upsampling if it is for print before finally saving to jpg.If it is for posting to the web use the save for web option.

It's best to save the Tiff file in case you want to do more editing on the picture at a later date. It will keep from multiple JPG compressions. I keep my TIFF on my HD but I have dual 200GB HD's. If you don't have that much space, burn them to CD.

No, the tiff is the best way to save it, burn it to a disc and it is there for future use, unspoilt by compression as with a jpg.
Of course save the raw file, that is your " negative "

I also recommend saving an intermediate in TIFF format. If file space is critical, most editing programs will allow you to save in TIFF format with the LZW option enabled -- this is a lossless compression scheme which reduces the size of the file on disk, but restores 100% of the image data when the file is re-opened.

Ever seen Spinal Tap?? 12 is better than 11, which is better than 10!! ;-)

Since you're using Photoshop what's wrong with the PSD format?

Why would you burn the tiff's to a CD, why not just burn the RAW's to a CD, that'e even better.

You may have altered the raw settings in which case you may not remember them, I save both.

Okay...Question:

Save the raw picture to a CD....would it be better to save the photo as PSD or a TIFF along with the raw picture?

Also...if you take JPG's...would it be better to convert it to a TIF/PSD to save on CD?

I wonder if I should change how I save....so I'm asking! :)

If I shoot jpg's as I did with my last camera all the time I would always save after editting as a tiff, it has no compression hence it is lossless. If you want to post here or to dpcprints (they won't accept tiff) you can still save as a jpg too. Opening and resaving as jpg will degrade it every time you save, so open the tiff instead.

I always keep all my .psd files in tact. After all whats the point of using layers if you ditch the .psd?

If you are using Photoshop, why would you archive in anything else than PSD? Uncompressed TIFF files are huge and there's no guarantee that your layers will be readable in other apps (there are a million different flavors of TIFF) or even in future versions of Photoshop. PSD uses lossless compression (zip, I believe), so the files are significantly smaller without any loss of quality. But more importantly, it's Photoshop's native format so you are guaranteed that everything is saved correctly and that they will continue supporting it.

Sameer, your original question is something I've wondered about too, so if you ever find out why their scale goes to 12, let us know!

i posted elsewhere too, but so far, people are indirectly answering the question. looks like no one knows.

Maximum in mine is 12 ? as for psd I never bothered because once edited to my satisfaction I thought flattening was irreversible once saved and closed, even when reopening a psd?
Looking at the size of my 16 bit tiffs ( 140mb )my last one, maybe I should use psd!

If space is not an issue, there is no need to flatten the layers. Create a new blank layer above all others and stamp it with what is visible from all lower layers (Alt-Ctrl-Shift-E). A Save as or Save for Web will not require the original PSD to be flattened.
