Before I do anything with my photos, I convert them from jpeg to tiff. I have two 24mb digital cameras and the resulting tiff files are easily handled by Photoshop Elements. However, I have recently had a problem with very slow opening of the iPhone tiff files, as well as problems with editing them. I finally looked at the file sizes and realized that the tiff conversion is creating 2G+ files. Since I've never had to deal with this before, I would appreciate some help in understanding how to keep the files a managable size without compromising quality. Thanks.
