This first image was taken on my first visit to the Bradbury Science Museum in Los Alamos, back in 2013.
This is the .jpg I have saved from then. At the time, I didn't have Photoshop or Lightroom. I used a Canon Rebel XTi and an 18-135mm f/3.5-5.6 IS zoom lens. Clicking the "get info" on the image says it was 1/60th of a second at f/5, with the lens zoomed to 60mm.
The XTi has a 10.1 megapixel APS-C sensor. It was Canon's entry-level DSLR in 2006, while the 18-135mm IS zoom was the kit lens that was bundled with the more upmarket two-digit "prosumer" Canons.
Yesterday I cropped the image and used the "auto" button in Photoshop for exposure and color correction. The result is below...
The image below was taken on this year's visit, five years later. I was using a Micro Four Thirds camera, an Olympus OM-D E-M5. The lens was the fantastic M. Zuiko 12-40mm f/2.8 Pro.
Unlike five years ago, I do have editing software now and shoot RAW instead of JPG. The image below is converted from the raw camera output into JPG by Lightroom, with no corrections applied.
That's 1/80th of a second at f/2.8 with the lens zoomed all the way to 40mm.
Again, I cropped it and just poked the "auto" button in Photoshop for exposure and color correction.
The
E-M5 has a 16MP Four Thirds size sensor, and was introduced six years after the XTi, in 2012, as a "prosumer" grade camera. The 12-40mm f/2.8 Pro lens is an extremely well-regarded piece of glass; it retails for $999, generally, although if you want to gamble with non-warrantee gray market imports, it's
cheaper. If I'd bought both brand new...well, let's say there's a reason I shop the used racks.
This was with the E-M5 and 12-40mm f/2.8 Pro, too...
