Is Editing Digital Photography Images Safe for Image Quality?
Some say that after you have your high quality, high resolution pictures and you want to put them on your hard drive and work on them for a little bit, it’s best to transform first the Jpeg files that come from you camera to tiff or other appropriate format, because working on jpegs might cause you to loose quality and color.
But transforming from JPG to something else has no relevancy as a first step of editing digital photography. The image is stoked onto your hard drive in a compressed format, named JPG. But the Pc’s virtual memory will unravel the image when you open it. Format issues can only arise after editing what you want and saving the final image. If the editing programs remains open, and you make a tiff save, the computer will use tiff compression methods to save a copy on the hard drive, but the original uncompressed image in still unchanged. The only quality changes are visible in the saved JPG, with because of the compression it’s normal to have less information.
It’s normal to make intermediary saves when changing a photo’s appearance because you never know what could go wrong. But when making these saves, be sure you make them under a digital photography format that does not only allow you to keep the image quality but can also save the image layers you might be working on. So this basically means you should save the intermediary images in the format that is specific to your photo editing software. This way, all changes become editable and reversible when you open the saved image again. Only at the end save the image in as a standard picture file, JPG, TIFF, GIF, depending on its purpose.
It’s a myth that circulated for a while and says that if you want quality pictures, the cropping is not allowed. Rotating and resizing the image will produce the generation of a new image, based on the old one, and the result will be better or worse depending on the algorithm used. Some algorithms eliminate extra unnecessary pixels, and others will simply enlarge existing pixels. photo printing services
