Reworking old photographs, here is a sample of a photo from 2006 taken with a Canon EOS 5D with a Sigma 50mm EX DG Macro lens. The location is the confluence of Cherry Creek and the South Platte River in lower downtown Denver. Back in that period, the Qwest building was the predominate landmark in night photos of Denver.

Master photo taken with a Canon EOS 5D. 12 megapixels.

I worked this photo in Adobe Photoshop using the Super Resolution function and was able to convert a 12 megapixel original to a 51 megapixel image. Again, I’m quite impressed as to how well I was able to increase the resolution of the image to the point it would print quite nicely at 24″ x 36.”

It’s difficult to see any fine detail with the original scaled to an internet image, so I did a 100% crop at approximately 800 x 600 pixels on the original raw file and the converted high resolution file. My sample crops are of the graffiti covered wall in the left-center part of the frame. A very small slice of the image.

This is the 800 x 600 crop of the original 12 mp raw file. Notice the difference in field of view between this and the crop of the 51 mp high resolution image.


Here is the 800 x 600 pixel crop of the 51 megapixel high resolution file.

I’ll be working on a write up for workflow for those interested. I’m still learning how to best use the super resolution tool and it involves interaction between Lightroom, Photoshop and DXO Photo Lab 4. The idea would be to get it down to the fewest steps if this is going to be a production project for older images in my portfolio.

Stay tuned.
