Now, this isn't my tip. I got it from my photography forum that I'm on, but it's great. However, nobody seems to know WHY IT WORKS, so can any of you experts explain it. By all logical conclusions doing this should deteriorate the image, but it doesn't.

.................................................................

I take it that you would like to produce a poster size image form your digital camera?

If so then:-

Open the image in Photoshop

Go to image>image size

Make sure that Resample is turned on, and change the Resample Image Interpolation Method to Bicubic Smoother.

Switch the unit of measurement pop-up menus from inches to percent and type 110, which will increase the image by 10%.

Now for some strange reason, which other on the forum may be able to explain, if you do this in 10% increments, it does not seem to soften or blur the image, try it.

..........................................................

The res showing on the screen shot for this was 72.

Hi Tosca.
I've used that before and it basicly boils down to pixel alteration.
See the below article:

i invented a different way too.

in Paint Shop Pro 9, i would need to resize things down a lot. they were simple things like logos. even though i was resizing them DOWN, they still became a little sketchy and distorted.

what i did was i Zoomed OUT and took a Screnshot. then i pasted the screenshot in the file i was working on. for some reason, that method resized the pics really good!


ill post some examples some other time so u can see for yourself side by side. im too lazy right now.

remember, this was with PSP9. i think photoshop does a MUCH MUCH better job resizing pics. i think i tried about every resizing option in PSP9 (except your way by doing it a 10% at a time) and this way was the best.
