People are usually afraid of working of plain Jpeg on their PCs after they collect them in that format from their digital photography apparatus, and are inclined in directly transforming them to tiff.
If you want to edit your pictures, the truth is there are many more stages you have to go though before editing the format. The image is stoked onto your hard drive in a compressed format, named JPG. The image that is read by the virtual memory is uncompressed. Format issues can only arise after editing what you want and saving the final image. When you save the image, if you choose the option JPG, the memory image will get compressed using the JPG algorithm, but the image will still remain uncompressed in computer’s memory and it will reflect the original image along with all the processed changes you brought to it, without losing any information through the saving process. What you have in the computer memory is not affected by a save during editing, as long as you use a different name for the new file.
The main idea is that you should make intermediary saves while you work, so you can get a sort of restore point, from witch you can continue work in case something goes wrong. These intermediary save will always be done under a format that is especially made for editing, that saves both quality and allows changes to become editable. The best thing is to choose the format that is recommended by the editing software you are currently using. Failing to do this will return an intermediary save that acts just like another image. Only when you are done editing you can same the image in a conventional format like JPG for online photo sharing, TIFF for images that are meant to be printed at high resolutions and so on.
Some people believe that if you crop in any way an image you will lose quality. Cropping results may turn up better or worse than the original, but it all depends on the functions used There are shrinking algorithms that eliminate extra pixels, and enlarging ones that make the pixel dots bigger. photo printing services
