[QUOTE="480sparky, post: 329179, member: 15805"] Here's a screen shot of five 100% crops of the same image: [IMG]http://i214.photobucket.com/albums/cc172/480sparky/Photography%202/100crops.jpg[/IMG] All are 100% crops..... 100% meaning one pixel in each image is displayed as one pixel on my monitor. Crop meaning each one (except for the bottom one) has been cropped, or whittled down, do a manageable portion so it can be uploaded to the innernets. The top left shot has been cropped to 400x600 pixels. The next one is 300x450. 200x300 is next, and 100x149 at the top right. The original image (of a sunflower, if you're wondering), is at the bottom.... the original finished image after my editing..... 3167 x 4750. You can see that each image displays the subject equally.... it's just that some of them are cropped down more than others. Now, here's the same image, but [B][I]rescaled[/I][/B] down to 800x533 pixels: [IMG]http://i214.photobucket.com/albums/cc172/480sparky/Photography/If_Morning_Was_A_Color_Post.jpg[/IMG] Obviously, the rescaled image allows you to see the entire image as intended, something you cannot do with the full-scale image ([SIZE=2]unless you happen to have a monitor that's 3167x4750 pixels AND you have turned it to portrait orientation!)[/SIZE]. The advantage of a 100% crop is you can take a portion of an image, upload it quickly to the internet, and others can view it and/or download it much faster than the full-size original. An example might be a noob wondering what a purple line is doing in her photo, so she's asked to upload a 100% crop of the issue. Then everyone says, "Oh, that's chromatic abberation.... totally normal. Your camera is fine! Here's how you deal with it......" The reason we ask for 100% crops is if anything less that 100% is offered, data is removed and crucial details may be missing. Anything more is extraneous and wastes bandwidth. Yes, you could toss out a 200% crop, but that would make each image pixel take up 4 pixels on the screen. They only solution to that is to view the image at 50%. [/QUOTE]
