I've been looking at some pictures I've taken on a HDTV and coming from a 4:3 camera, there's a little bit of vertical black strip thing happening with most pics.
That leads me to want to crop them to fit the 16:9 display it has...
But then if I want to look at a picture on a computer monitor, that's 5:4 or 8:5 (e.g. WUXGA)
And then there's the size of paper - different ratios again!
Sometimes a picture is only right in one size but sometimes there's a desire to fill the entire screen (or piece of paper..) because the subject is well centred and it's just a matter of how much ... trimming to remove.
Ideally I'd like to create just one set of jpegs or "to print" picture files, but I'm starting to wonder if that's too naive on my part.
What do others make of this conundrum?
Are there any software packages (or file formats) that allow you to store a "recipe" for rendering a picture from a raw file that contains different instructions depending on what the output device is?
I really try to compose in the camera, and when I work on an image I try to make every pixel contribute to the over-all effect. As a result, I don't like cropping good information out of an image. (Of course, if I am printing to a certain aspect ratio, I have to go back on this principle. If I know ahead of time that I will have to end up with a 3:4 or 4:5 aspect ratio rather than my camera's 2:3 I will try to shoot with lots of extra around the image so that what I wanted will still be there after the crop.)
When it comes to producing images for the web or peopl's monitors or TV screens, if they are images that are already worked on, I leave them at 2:3 and hope that they will be shown to "fit the screen," meaning that the longer dimension will just fit the screen. This of course will leave black borders on the other 2 sides, but I find that preferable to cropping out part of the image or "stretching" the image to fit the whole screen.
On the other hand, if I am doing a digital slide show for specific output, I will find a complementery, nondescript border for all of the images, that will fill the screen in that format, if it is different from my camera's aspect ratio.
