Twitter and Dropbox aren’t really known as premier destinations for sharing photographs online, but both companies are taking steps toward changing that. Both companies unveiled new features today that are geared toward making photo sharing and viewing through their respective services an easier and more enjoyable experience.
Last week, we pointed you to a piece by the New York Times on how Fujifilm is attempting to kill moiré without killing sharpness by designing its sensors in a way that eschews the traditional anti-aliasing filters used in digital cameras. Photographer Martin Doppelbauer disagrees with Fuji’s claims: he has published a piece arguing that, “digital cameras without aliasing filters are cameras with a built-in design flaw“:
To omit an alias filter in front of a digital image sensors is like building a sports car with no brakes. Of course, the car accelerates a little faster due to the lower weight and the cornering ability is also better due to the smaller unsprung weight – but ultimately it lacks an essential functional element.
For analog cameras, an alias filter is not required: Film has no sharply defined limit of resolution. It loses contrast and resolution gradually with increasingly higher frequencies. You could say, the low-pass filter is already incorporated in the film itself.
[…] By omitting the alias filter, the recorded image information […] does not increase! Even though images of cameras without aliasing filters may appear sharper and crisper: Images of cameras with a proper alias filter can easily be re-sharpened to achieve the same visual impression – without side effects.
So according to Doppelbauer, the recent fascination with removing anti-aliasing filters is more based in marketing rather than science.

French optical filter company Cokin has launched a new line of lens filters under the brand name Pure Harmonie. The new filters are unique in that they’re the thinnest and lightest in the world — the UV filter in the set measures only 3.3mm (~0.13in) thick!
The Brazilian advertising agency Y&R recently came up with an extremely clever series of photographs for Colgate to promote the company’s line of Total dental floss. Check out the three couple portraits in the post and see how quickly your eye is drawn to the weirdness.
Reikan Technology, the company behind the FoCal automatic lens calibration tool, tells us that it has released a new web-based tool for researching the performance of camera and lens combinations.
Have you always wanted to see what the world looks like from the top of the Burj Khalifa, the tallest manmade structure in the world? Dubai, UAE-based photographer Gerald Donovan was recently given the opportunity of shooting a photograph from the peak of the massive skyscraper. Not just any ol’ photograph, mind you, but an immersive 360-degree panorama that makes you feel like you’re actually there!
It seems camera companies are trying to target Japanese anime fans these days. In September 2011, we wrote about how Leica had teamed up with the designer of Gundam (not to be confused with Gangnam) for a limited edition mech-themed V-LUX 30 digital camera.
Now Pentax, the king of bizarre special edition cameras, has forged an anime partnership of its own. The company has announced a limited edition line of Q10 mirrorless cameras that carry Neon Genesis Evangelion branding and colors.
This is probably the most beautiful video you’ll see today, this week, and perhaps even this year. Titled “Full Moon Silhouettes,” it’s a real-time video captured by photographer Mark Gee at Mount Victoria Lookout in Wellington, New Zealand. Gee writes,
People had gathered up there this night to get the best view possible of the moon rising. I captured the video from 2.1km away on the other side of the city. It’s something that I’ve been wanting to photograph for a long time now, and a lot of planning and failed attempts had taken place. Finally, during moon rise on the 28th January 2013, everything fell into place and I got my footage.
The video is as it came off the memory card and there has been no manipulation whatsoever. Technically it was quite a challenge to get the final result. I shot it on a Canon ID MkIV in video mode with a Canon EF 500mm f/4L and a Canon 2x extender II, giving me the equivalent focal length of 1300mm.
If you liked this one, also be sure to check out this video we featured earlier this month of a man slacklining in front of the moon.
Thanks for sending in the tip, Sam!
Nikon just overhauled its entire compact/superzoom lineup, so we thought we’d give it a go at a broad overview. New camera models are the Coolpix P520, L820, AW110, S9500, S9400, S5200, and S31; and all of them are trying to compete with your smartphone by offering a mix and match of great zoom, Wi-Fi connectivity and GPS.

There’s a new photo sharing app in town called Reactions. That news isn’t particularly unique or exciting in itself, but the developer behind the app is rather noteworthy: it’s legendary hacker George Hotz (AKA “geohot”).
