Walker Evans’ famous photo book “American Photographs” was first published in 1938. Since then, the book has been released in new editions every 25 years or so. Although the photos contained within its covers have remained the same, the processes and technologies used to print the photos have evolved over time, causing each edition to be every so slightly different from the others.
A few weeks ago, we casually remarked that the best cameraphones today can probably snap better photos than top-of-the-line compact cameras from over a decade ago. Turns out that it’s true.
Earlier today, Apple announced its new iPhone 5, which features a camera that’s nearly identical to the one found in the 4S. Soon after the announcement, Apple put up the official product page for the phone, which includes a gallery of sample photographs shot using the iPhone 5. Unfortunately, none of the shots show low-light environments, which would have allowed us to gawk at the power of the camera’s new and improved noise-killing processor. For now, we’ll just have to settle for these generic shots showing what the 3264×2448 images look like when they pop out of the camera.
Nokia’s 808 PureView phone packs a hefty 41-megapixel sensor, but how do its megapixels compare to a “real” 40+ megapixel camera photo? Spanish website Quesabesde decided to find out by putting the phone head-to-head with the 40MP Pentax 645D medium format DSLR. They shot the same scenes with both cameras, and blew them up to examine the quality. The article is in Spanish, but a little Google Translate magic does the trick.
UV lens filters are a popular way to protect the front element of lenses from damage, but you should make sure you invest in a high-quality one unless you want to make a huge sacrifice in image quality. Reddit user EvilDoesIt shot the photos above comparing a cheap filter with a pricier one:
The top one is a $20 Quantaray UV filter. Bottom is a ~$70 B+W MRC UV filter. This is a more extreme example, but it shows the difference between a nice filter and a crappy cheap one. Both these shots are unedited JPEGs from my Nikon D7k with a Nikkor 17-55 ƒ/2.8 @ 1.3s ISO100.
I do realize that the top pic can be easily fixed by adjusting levels, but in my opinion, it’s always better to get the best picture you can get out of your camera before editing. [#]
His last sentence is a gem: to achieve the best images, you want to make sure you’re squeezing out the best image quality you can from each step along the way.

Camera rating business DxOMark has published its in-depth sensor review for the Canon 5D Mark III. For Canon fans, there’s both good and bad news: while the camera boasts the best sensor seen in a Canon DSLR so far — besting the sensor found in the 1Ds Mark III — its score of 81 is far below the Nikon D800′s 95. DxOMark does, however, point out that the two cameras focus on different strengths:
The duel between the Nikon D800 and the EOS 5D Mark III would most certainly take place except that the different sensors each one has adopted makes it difficult to do a head-to-head comparison. Both sensors offer different advantages —in principle, sensitivity for the Canon and definition for the Nikon. With its 36 megapixels, the Nikon D800 clearly has concentrated its efforts on fine detail reproduction.
For its part, the Canon EOS 5D Mark III chose to make a grand compromise: with its 22 megapixels, it offers both higher definition and in theory, higher sensitivity.

Turns out the 36.3 megapixel sensor inside the new Nikon D800 isn’t just a megapixel war marketing tactic: the sensor has been given the highest score ever awarded by camera equipment rating service DxOMark. Calling it a “complete success in every sensor-related respect”, the lab states that the D800′s sensor has become the new sensor of reference by which all other camera sensors will be measured. Furthermore, it boasts an “unmatched quality-to-price ratio” by being the cheapest (by far) among the 8 top cameras. The sensor is even comparable in quality to the best medium-format sensors out there, and even outperforms them at higher ISOs. Check out the full review for a more detailed analysis of the sensor and how the D800 stacks up against competition.
Nokia has released a set of sample photographs in order to show off the camera quality of its new 41MP 808 PureView camera phone. The 33.3MB ZIP file contains just 3 untouched JPEG images — the largest of which (seen above) is a 5368×7152, 38-megapixel photograph that weighs in at 10.3MB. The quality is quite impressive, given that the images were captured with a phone.
