Newbie Tiff vs. Jpeg Questions

I am starting to scan — with a Nikon film scanner — old family slides into digital photos. Because I eventually want to print some of those scanned photos, I have scanned the small slides using a very high resolution and have saved the photos in the Tiff format. I am using PS CS to clean those high resolution photos up.

I had two newbie questions. First, is there a photo print service that will reproduce the photos with the Tiff format? If not, am I unnecessarily worried that converting the photos to an excellent quality Jpeg format will reduce the quality of my Tiff photos? Put more succinctly, will the conversion to Jpeg destroy a lot of the resolution in the Tiff photos and/or will the conversion to Jpeg bring grain into the photos?

Thanks.

You have to talk to the print service. It’s that simple phone them and ask.

Most print shops will happily deal with jpegs or tiffs

Many thanks for your reply. Do you have an opinion on the second question, namely, will the conversion to Jpeg destroy a lot of the resolution in the Tiff photos and/or will the conversion to Jpeg bring grain into the photos?

Thanks,

If you use the highest quality JPG setting when Saving As, you will not notice any quality loss. If you continue to save the JPG over and over, you will start to see artifacts. Undesirable! Every time you save a JPG it compresses using whatever setting you initially save it at. Do all your work on the Tiffs. You can save as much as you want without quality loss. When you are happy with your work, Save As to a JPG. If this is even necessary. I would think any professional printer could handle a Tiff. If not, you’re at the wrong printer.

I’m a consumer and hobbiest rather than a pro, but here is how I do it. Working and saving as TIFF files is a lossless file format, while JPEG as you probably know is a lossy format. If you save once or twice in JPEG, you are probably not going to loss a great deal of noticeable resolution if you’re compression level is set minimally at 1 or so. Each time you save the file in JPEG it’s going to become a little more lossy. What I like to do is first convert the original image to TIFF and "save as" TIFF file. Using "save as" will preserve your original in it’s original format as a backup, and you never have to work with it again unless you goof up or destroy your TIFF file. I do all subsequent image editing on the TIFF file, and continue saving it as TIFF. The print shops in my city will take either JPEG or TIFF files for digital printing. "If" I want to convert back to JPEG at the end of all editing, I can do so by setting the compression level all the way to minimum. This one-time save into JPEG should not make a noticeable change. If you do this as a "save as", you will have two copies–the edited and finished TIFF, and an edited and finished JPEG. Good luck!
