Photography Question

Photo resizing!


I have been very frustrated in resizing my digital file to print a quality 11X14 and 8 X 10s. I use photoshop 6.0 and elements 2.0. I know how to request a file to be an 11X14. However, when I try to save it, it will not save. Only when I use the crop tool it seems to save it, but then I must crop out things that I want at both ends or even top and botton of my photos. I want to print the whole entire photo at 11 X14, what do I do? I don't want to crop anything out. I use a reble XT 350D 8 megapixals, and the normal file size is 3456 X 2304 and X 24b whatever this last number means. What does this number represent? So what does a person do? Is there not a way to print the complete contents of a photo file without having to crop anything out? I hope this is not the case, otherwise, this sucks big time, there has got to be a way. As you can see, this is very frustrating indeed and I need someone who knows how to do this to advise me, help me please! :-(

  Lani, you must understand that the ratio of width to height on an 8x10 (0.8) is different than on an 11x14 (0.785). This effectively means that if you want to print the same original image in both sizes, you will necessarily lose some portion of the image. Think of it like trying to make that 11x14 into a square 8x8 print - or even an 11x11 square print - you can see that the different ratios necessitate some image cropping someplace. Of course, the difference between 8x10 and 11x14 isn't that dramatic, but I wanted to give you an obvious example.

As for the 24b number, I'm not a Canon user but I'll wager that just refers to the color depth of 24 bits (8 bits perchannel of red, green and blue). This is the normal way color images are stored and recorded; each individual pixel has a theoretical limint of 16.7 million colors this way. There are devices that can capture at 14 or 16 bit-per-channel color; then the file sizes get larger and other things can be done. The point is, Photoshop can handle those 16 bit-per-channel images and so it must be indicating that yours are 24 bits "deep" (as they say).

Hope that helps
