We've been fans of Aaron Johnson's comic strip 'What the Duck' for years. 'WTD' is one of the best satirical comic strips in the world, and it's published here every week, as well as being included in our weekly newsletter. Barbed, topical and always amusing, we hope you enjoy WTD as much as we do. Click through for this week's strip.

The Phottix BG-5DIII battery grip is a budget-friendly alternative to Canon's BG-E11 battery grip for the EOS 5D Mark III, allowing you to double the battery life and enhance handling when shooting vertical format images. Can it do the same job for less cash, or should you save up for the Canon-branded accessory? Find out in our review.

Video sharing service Vine has generated a lot of buzz in recent months. Vine allows you to share videos of up to six seconds in length as either a single continuous take or as a 'collage' of short duration clips. Art Director Jethro Ames saw Vine as a challenge and decided to push his limits to see what he could do with the app. The result is a series of imaginative timelapse videos that are perfectly executed down to the last detail.

In a brief note on its Japanese website, Sigma has announced that the Sony and Pentax mount versions of its highly-regarded 35mm F1.4 DG HSM 'Art' lens will go on sale on 31st May. It's also announced that the Nikon-mount version of its 120-300mm F2.8 DG OS HSM 'Sports' telephoto zoom will be available at the same time. We gave the 35mm F1.4 our Gold Award when we reviewed it back in December, for its combination of exceptionally good optics and solid build at a price rather lower than the camera manufacturers' equivalents.

Canon has patented a color-sensitive multi-layered sensor design, showing the company is still pursuing the technology. Like Sigma's Foveon chips, the multi-layered design allows each of the sensor's pixels to capture color information without the need for colored filters. The patent, discovered by the Japanese Engineering Accomplishment blog, suggests a system to promote resonance within the sensor, in an attempt to make the lower layers of the sensor more sensitive.

If you've never had the chance to stand in the front row and shoot a live concert, Montreal-based photographer Pierre Bourgault has the next best thing. He attached a GoPro camera to the top of his Canon DSLR and recorded a seven-minute video of his shooting experience at a Dead to Me concert. He then overlaid the actual photos taken at the show, which you can view after the break.

Leica has placed a teaser on its Facebook page for a new 'Mini M' camera to be launched on June 11th, that apparently will slot into its range between the M rangefinder and the X2 fixed-lens compact. It's given no other details, but we think it could make sense for the company to produce a full-time live view version of the M Typ 240, using the same sensor but with the expensive rangefinder assembly removed. This would result in a 24MP full frame mirrorless camera that would be able to use almost any manual focus SLR or rangefinder lens ever made, without a field-of-view crop. 

Fujifilm has updated the firmware for its X-Pro1 and X-E1 mirrorless cameras, to improve the autofocus speed with the recently-launched XF 55-200mm F3.5-4.8 R LM OIS telephoto zoom lens. Versions 1.05 for the X-E1 and 2.04 for the X-Pro1 are available to download from the Fujifilm website.

We just published the DxOMark Mobile Report for Samsung's new flagship smartphone, the Galaxy S4 on connect.dpreview.com. DxO's imaging experts have analyzed 14 aspects of mobile imaging including detailed image quality assessment, flash performance, autofocus reliability and more to calculate a final score. This report will be integrated into our full review once it is finished but for now click through to find out how the Samsung Galaxy S4's camera performed in the DxOMark lab tests.

We've just added three studio comparison pages to our previously-published preview of the Pentax MX-1. The MX-1 is Pentax's flagship compact camera, and something of a departure for the manufacturer, offering a fast F1.8-2.5 zoom lens, full manual control and a high-class, metal body, to compete with more established peers like Panasonic's LX7. Click through to go to the new pages in our preview, and see for yourself how the MX-1 compares to its rivals.  

Much of the fallout surrounding Flickr's massive updates this Monday continues to center around the legacy 'Pro' accounts and a contentious statement from Yahoo CEO Marissa Mayer: 'There’s no such thing as Flickr Pro today because [...] there’s really no such thing as professional photographers anymore.' She apologized today for her 'misstatement', and it appears that existing Flickr Pro account holders will still be able to take advantage of unlimited storage.

Animated flipbooks have been around for nearly 145 years. With just a little thumb action, these books allowed you to view a few seconds worth of animation. Now, a new concept camera known as the Gifty allows you to record video and print a flipbook instantly. The only problem: you can't buy one yet. 

If you've ever wondered who to thank (or blame) for those 8-bit animated graphics that remain prelevant even on today's high-bandwidth Internet, Steve Wilhite is your man. He was honored for that achievement at this year's Webby Awards and took the opportunity to once again remind us how 'GIF' should be pronounced. (via New York Times)

We've just posted our review of the The Olympus PEN Mini E-PM2. The E-PM2 is an entry-level Micro Four Thirds system camera, with a 16MP CMOS sensor and full 1080 HD video. It's one of the smallest mirrorless cameras on the market and boasts 8 frames per second continuous shooting. This second generation 'Mini' is effectively the image quality 'guts' of the OM-D in a compact, lightweight, novice-friendly form. Click through to find out what we think of it.

When homes are damaged, often the most important items cannot be replaced. For victims of fire, floods and other natural disasters, family photos are among the worst things to lose. Operation Photo Rescue brings together victims with professional photo editors to turn damaged images back into clear memories.

Flickr fans may find the lure of a free terabyte attractive, but they might be put off by the accompanying advertisements that support Flickr's new free account model. A major update to the photo sharing service has completely revamped the look of accounts and restructured the way users may pay for Flickr in the future. We take a look at the changes on connect.dpreview.com.

A cover image in the latest issue of the New York Times' monthly style magazine, T, has led to an interesting discussion about the newspaper's policy on photo retouching. While editors forbid any image manipulation beyond, 'minor color-toning and brightness' in news stories, retouches and removal of blemishes are allowed in the style magazine's fashion photography. Does a newspaper risk credibility by allowing retouching on editorially-branded content? Click to read more and share your thoughts.

At last week's I/O developer conference Google announced a number of upgrades to the photo section of its Google+ social network, including features such as 'Auto-Highlight', 'Auto-Enhance' and 'Auto'-Awesome'.

Lindsay Adler and Erik Valind, both working professionals and educators, have written a beginner’s guide to photographic lighting with an unusual conceit at its core. By structuring a book around a list of common challenges - what they call the 'top ten worst situations' - they've created a digestible, useful 'lighting 101' guide. In this short review, Adam Koplan takes a look at their book 'Shooting in Sh**ty Light: The Top Ten Worst Photography Lighting Situations and How to Conquer Them'.
