Preserve Your Privacy by Pixelating Photographs with PhotoHide

Hiding or censoring part of an image through obfuscation is as easy as selecting the area in Photoshop and applying the Pixelate->Mosaic filter, but what if you don't have an image editing program at your disposal? If you're seriously paranoid about your privacy on the Internet, there's a new service called PhotoHide that helps you quickly add these pixelated areas to any photo. Everything is done through the web browser, and you can download the final image once you're done.

World’s Largest Indoor Photo Weighs in at 40 Gigapixels

Photographer Jeffrey Martin, founder of 360cities, recently use a Canon 550D and 200mm lens to shoot the largest indoor photograph ever made: a ginormous 40 gigapixel photograph of a 18th-century baroque library in the Strahov Monastery in Prague, Czech Republic. Over 5 days of shooting with his robot control camera, Martin collected 2,947 separate photos that went into the resulting panorama. The RAW photos then took a day to batch process, 111 hours to stitch, and 20 hours to Photoshop, finally ending as a single 283 gigabyte photograph.

Debate Over Fabienne Cherisma Photos Rekindled After Award Given

During the aftermath of the devastating earthquake in Haiti, a number of images that became widely discussed were of 15-year-old Fabienne Cherisma, who was shot and killed by police after looting two plastic chairs and three framed pictures. One of these photographs (shown above), captured by photographer Paul Hansen, was recently chosen as the best International News Image at the Swedish Picture of the Year Awards. There was soon a good deal of discussion in the Swedish media over the ethics of such an image.

Pinhole Cameras Made with Photo Paper

Photographer Thomas Hudson Reeve shoots pinhole photographs in a pretty interesting way -- rather than using photo-sensitive paper or film inside a separate camera, he creates the camera using photo paper itself. The resulting photograph is exposed onto the inside of the photo-sensitive camera (which he calls the "PaperCam"), and creates a pretty surreal look when opened up and developed.

Use a Field Notebook to Jot Down “EXIF Data” for Your Film Photos

One of the big advantages of digital photography is that EXIF data is embedded into your images, allowing you to easily learn when and how (and more recently where) a particular photograph was captured. If you still enjoy shooting film, then a solution is to jot down notes about your photography while you're shooting.
