Best way to make a large print from a small file? (Page 2): If increasing an image by that big amount, use a dedicated program like Resize, or similar, but don't expect miracles!

I'm thinking of resampling it by 100 pixel increments, using Automatic in Photoshop CC, up to 1800 on the long side, then printing at 100 pixels/inch.

Anyone got a better recipe?

Interesting. Yours is the second reply arguing against incremental resizing. Not long ago, I seem to remember, it was fashionable.

"Print it and see" is the usual fall-back option. Saving paper and ink never trumps pleasing the customer.

Heyho,

Alan.

Incremental resizing wasn't just "fashionable", in early versions of Photoshop it was effective. But since then Adobe has upgraded so that it isn't necessary or effective.

Thank you for that. Can you point me to that Adobe upgrade?

i'm not sure which version of Photoshop first had that upgrade, but any recent version has it.

About 6 months ago I had to resize a standard APS-c image to print to a 9' image for a large format wall graphic. I did in house tests by trying incremental steps, and then just going for it in one step. There was virtually no difference, so I went in the end in one step resizing. I was using the latest Photoshop CC release at the time. By the way, the image turned out great.

Yup, I have an 80" wide print from a D-7000 16mb aps-c sensor that actually looks sharp at less than 1'. A lot of it (actually the majority) depends on just how sharp the starting image is. To me, it just proves that the pixel count war has gone past it's useful stage, and is now more about marketing.

It’s such a highly textured image that I think it’ll look fine blown up to 13x19.

Adobe is made of soft clay... There are two programs dedicated to excellence in upsizing. On1 [historically called perfect resize] and Photozoom by BenVista. Both use special algorithms and at large % resize leave other programs wanting. Most any edit program will do smaller % resizing OK but fail at hi %.

Photozoom 6 is not current, 7 is. But for $20 you can get 6 from Ashampoo.
https://www.ashampoo.com/en/usd/psr/partner0106/partner-software/photozoom-6

examples are given in an article by Ashampoo addressing Photozoom 6: "Even extreme enlargements of more than 800% that would render useless results with other applications are now possible. This helps restore even the smallest details in your photos. PhotoZoom #6 can enlarge your images up to 300.000 x 300.000 pixels, far beyond any digital camera!"

This software will resize a photo with excellent results IF you're starting out with an image taken with a 8-10 MP camera and is excellent quality. ON1 Resize 2018. They may have a trial and if so, try it.

I bought a program some 15 years ago called Genuine Fractals. Not that I had any real use for it. It just sounded like a really interesting approach, and it had the word "Fractals" in it. Doing some large prints in the last year I remembered it. Naturally the old program was unusable but I did contact them and was directed to the updated resizing application in ON1, with a discount, as it was an upgrade.

If you use Photoshop CC 2018, there is a new Image Size resample filter called "Preserve Details 2.0" and it works really well! It's not enabled by default however. To enable it, go to Edit, Preferences, Technology Previews, and check "Enable Preserve Details 2.0 Upscale". The option will then be a available as a resample filter when you go to Image, Image Size.

Photoshop is very effective, but I am a fan of ON1 resize for the simplicity and results. The ON1 system is very well thought out and getting better every year.

Upscale in ps 9% at a time. I don't remember why, but that is what I was taught.

You must have been taught that long ago. It no longer applies. And it was 10%.
