Converting JPEG to TIFF... I was wondering since I have hundreds of pictures already stored on my computer in JPEG format, if I take the pictures I really like and open them up in Photoshop and then save them (without any changes or manipulating) to TIFF, would I retain a high quality image? In other words, is it worth me changing my JPEG pictures to TIFF format? I have all the original pics that have not been edited in any way. They have all just been saved on the computer as a JPEG. Should I change them to TIFF then edit them or just forget about changing the format? Any help will be greatly appreciated. Thank you

Hi Michael I'm not an expert, but I believe that you would only need to change the format, if you are going to edit your photographs. If you're using Photoshop, duplicate the original and save as TIFF, PSD or RAW and make your changes. Especially, if you intend your photographs for print. Each time you edit/save an image in JPEG format, a small portion of the image information is lost. Hope that helps.

AS long as you aren't opening and resaving as jpgs, your images are fine as they are. Mary is correct, you only need to change the format if you are going to edit the photographs. Jpg format is a "lossy" compression format, which means each time you resave a jpg, you lose more information. Your images will degrade each time you resave it as a jpg. With tifs, you can resave as many times as you like without the quality of your image degrading each time you save. You can compress your images somewhat, but it is a lossless compression. Each has its advantage. JPG allows you to compress your files to very small file sizes, but will lose info each time you resave as a jpg. With tifs, you can save as many times as you like, but your file sizes will always be bigger, using up your hard drive space. Since your pictures are already jpgs, it doesn't make sense to resave as tifs unless you have the time and unlimited hard drive space.
