Canon 12x IS USM (S3 IS built-in Lens) -- 36-432mm (35mm EQ)

I've had a program/filter in the past that was Photoshop friendly that would upsize my images and still give me great detail and resolution.

I've forgotten the name.

But, I don't need that one... if you folks have a different suggestion for me.

I have a friend's 4 x 6 inch photograph. She wants to make a larger canvas out of it.

What do you recommend, please?

Are you saying you have a 4x6 print(?), or, if already digital, we need to know the dimensions in pixels to give a meaningful answer ...

And, what size canvas are you printing?

Thanks, Gen.

I've scanned the physical print with the best scanner I have. It's now digitally 999 x 775 pixels.

She wants to go something like 10 x 12".

Check with the place you're printing, but I think you can get away with a lot lower resolution on canvas.

If you still have Photoshop, the simplest path is to try upsampling using the Bicubic Smoother setting to 200% (should give you enough resolution to print at 150 ppi).

One of the new editing programs (Aurora?) for which I see a lot of ads has an new ai-driven upsampling feature which looked pretty good in the demo sample. If you're interested I can try and track it down (later today) ...

Thanks again, Gen!

I'll try it and see. She's going to print it (different state). I'm going to send her the file.

I had something that was specifically an upsize tool... wish I could remember it. But, that was two computers ago. *sigh*

Unfortunately, this is the image (after I removed the telephone pole out of the top of her head).

Missed focus makes it even harder.

Any ideas?

Sean Bagshaw recently posted a YouTube episode comparing multiple ways of up-sizing images (here). Gigapixel AI was his favorite, but it takes a long time per image unless you have a moderately high end video card and recent powerful CPU. It does perform a bit of sharpening, and my experience with it is that the artificial intelligence aspect seems to help (although producing artifacts in some images). A recent 25% off sale may still be active (check website of Topaz Labs, which sells it). Maybe try the Photoshop method Sean reviewed before deciding to spend money.

Sent you a PM with results of doing some work on the version you posted.

Might have been Genuine Fractals? That's one reason I keep old computers/software around ...

BoB! That's amazing! You're such a sweetheart to use your time on my image!

Thank you bunches! I'll look into the cost...

Gen, Yes!! That was it! Genuine Fractals. I wonder if I still have a CD somewhere...

I think what is left of Genuine Fractals is now part off ON-1.
