Resize Question
Aug 7, 2015 09:50:23 #
A question was raised again about resizing photos without losing data.
Image 1 = my original cropped to a 3:2 format or 4x6/8x12 print format.
Image 2 = Image 1 put into a 5:4 format for printing 4x5 or 8x10 prints without losing any data. This was done in PSPx6 with the "Canvas Resize" option.
Image 3 = Image 1 put into the 5:4 format for printing 4x5 or 8x10 prints without losing any data. This was done in PSPx6 with the "Resize" option. The sample I used will be difficult to notice the differences, but this image was "stretched" vertically to fill the white spaces that exist in the Image 2 sample.
The Image 1 was 4000 pixels wide by 2667 pixels high. For this to print at 4x5 or 8x10 proportions I divided the 4000 by 5 (5 inch) and multiplied the result by 4 (4 inch) to get the final pixel height of 3200

Some images will be difficult to tell how you stretched it, but other images will show very plainly. It will all depend on the content.

For many object it will be barely noticeable, but be very careful if there are people in your photo. Stretching top to bottom may not be too bad, it will make everyone look slimmer than they are and especially the ladies may not object to this. But it will also stretch the faces and make them look like caricatures.
Stretching sideways will make people look fatter than they are, and again, especially the ladies will not thank you for that, and I'd think many gentlemen won't either.
Much better to make a plain background document of the size you need and superimpose your photo on that. Yes, you'll have white space, but not distorted bodies.
For many photos, I have superimposed the photo on the white space so that three sides "touch" and used the white strip on the fourth side for the "story" about the photo. This could even be done for photos that will be frames, and instead of cutting off the white space, hide it with a mat. The story could be written on the dust cover, but if the photo is ever taken out of the frame, it will still be there.

Wahawk,
I think you will find using Paint Shop Pro X-1 thru X-7 the "Resize Tool will provide the best image if you first save the out of camera image in .pspimage format and work on that file. Then you can crop the image to print size, and apply the Resize Tool to maintain the high dpi values from the original file.
You will be able to apply a tiny amount of Unsharp Mask to recover some of the sharpness lost in the resizing operation.

There was a topic last year where stretching the image wasn't feasible, and a similar suggestion to Morning Star's was made about writing something about the shot in the white space.
It worked great because the subject was something like a winning baseball team, so they could print the date, team name and so forth.
This is a 3:2 image that can't be printed as 8x10 without losing some of the pic, or stretching the image as Wahawk demonstrates.
The outside dimensions, including the white space, are now 8x10.

How about showing your image in a 'stretched' version and see how much different it looks??

For 8x10, actually not that bad if you don't know how the mountain should look :)
Original on left, re-sized on right.

Differences are subtle if you don't know the real view but are very significant if you see the original or actually know the view!!
Thanks for adding your examples.

I just saw another question about this. They were asking about taking an image like my first one and turning it into a vertical without losing any information or parts of the image.
I took my Image 1 above that is in a 3:2 format (4x6 or 8x12 prints) and resized it to be able to print an 8x10 vertical without losing any of the image!! But WOW!! Look at the distortion!!

A very interesting exercise in correcting a very common mistake that all too many "photographers" make. Seems like too many people want to just go shoot pictures & FIX them later on & spend hours tweeking exposure, sharpness, composition, etc. at their computer.
If you consider what size prints you may want BEFORE you press the shutter button, the resize question would not exist! Composition (as it relates to print size)is probably the most overlooked element in photography.
Seems like folks are more interested in how to use Photo Shop than how to take a good photo. Back in the day, we had questions about how to take a good photo, NOW the questions are about how to FIX a bad photo.
Sorry, didn't mean to get off topic.

It also happens frequently, that I want to print a 4x6 AND a 5x7 of the same image. And it happens equally often, that I don't decide that till after the shutter release button has been pushed.
So instead of pulling out my hair afterwards, I take all photos at the largest resolution and aspect ratio my camera allows, and take in a bit of extra space around the subject so that I have space to crop.

You must have skills I never knew existed, if you can compose for an 5X7 or an 8X10 in the camera viewfinder, before you press the shutter release.
My cameras (one full frame, one crop frame) have sensors with the 2:3 aspect ratio, as in the original 35mm format. I always compose for that ratio, and I don't think I could figure out how to frame an 8X10 or a 5X7 if I had to. Do some cameras have guidelines in the viewfinder that show these aspect ratios?
My biggest frustration is trying to find a shop that will print large prints in the original 2:3 aspect ratio. I recently went to print three different photos at 16X24. One shop could only do 18X24, and the other 16X26. I don't get it, but that's what I had to deal with. So, besides resizing, I had to figure out where and how to crop the original 2:3 ratio.
I must take issue with your assertion that:
...If you consider what size prints you may want BEFORE you press the shutter button, the resize question would not exist! Composition (as it relates to print size)is probably the most overlooked element in photography...
I always consider composition before I press the shutter release, and, as I noted above, I still have to wrestle with resizing, cropping, etc. to get my images printed.
