Large print from cropped 8MP sensor (Canon 30D)

[Ransome]

Hello, first post here.

I've been a long term Photoshop (elements) user, but rarely use it. I primarily use Aperture. I have a shot that I've printed successfully in 20 X 20 on aluminum and would like my next print to be bigger, 30 X 30 would be ideal. I have a JPG Aperture export that measures 2318 X 2318 pixels. I was talking to a person at an art show this weekend, discussing my goal for this photo and he mentioned a feature of Photoshop that can take this image and basically adds more pixels. It's a 3 second motion shot in low light, so I'm not too worried about losing sharpness. Can anyone guide me to the capability that will do as described above?

Here is a 1024 X 1024 export of the photo. Thanks in advance.

You are talking about "image resizing with resampling". For a general introduction, read this:
http://help.adobe.com/en_US/photoshop/cs/using/WSfd1234e1c4b69f30ea53e41001031ab64-7945a.html

If you can't be bothered with all the introductory material, scroll down to the section on "resampling" and "change pixel dimensions of an image".

I have a problem with some of the technical details in Adobe's article, but still, it's a decent, concise introduction to what you need.

If you don't like the results you get with native Photoshop resampling algorithms such as "bicubic", there are two commercial products you should look at:

PhotoZoom Pro:

and,

Perfect Resize (aka, "Genuine Fractals"):
http://www.ononesoftware.com/products/perfect-resize/

That being said, good, specialist printers will have available and be intimately familiar with all three of the above methods as well as software called a "RIP engine" directly connected to their printer and optimized for it.

My recommendation is that your very first step should be for you to discuss this with your printer, and then have them print a crop of a small area at the intended magnification (say, winding up with an inexpensive 8 x 10) for you to evaluate their resizing method.

HTH,

Tom M

Tom,

Thank you for this information. I will definitely read the material, I just needed to pointed in the right direction. More to the point, I have to get off my butt and learn this product. My daughters just starting in LR 4 and if I'm not careful, she will pass me up quickly.

Best,

Tom,

Thank you. I've resized before, just never used the scaler tools. I think this will work.

Best,

Ransome
