seashore.sourceforge.net reports: [edited]

Seashore is an open source image editor for Mac OS X's Cocoa framework. It features gradients, textures and anti-aliasing for both text and brush strokes. It supports multiple layers and alpha channel editing. It is based around the GIMP's technology and uses the same native file format.

However, unlike the GIMP, Seashore aims to serve the basic image editing needs of most computer users, not to provide a replacement for professional image editing products. Also, unlike GIMP, Seashore has an all-new Cocoa UI that will fit right in on Mac OS X. Seashore was created by Mark Pazolli who led the project until the end of 2009.

Sony SLT Alpha A55

Digital Photography Review has published an in-depth review of Sony's latest 'mini-DSLR'.

Excerpts from the conclusion follow:

The A55's 16.2MP CMOS sensor is new, and in collaboration with the camera's image processing, it offers excellent image quality. JPEG image quality is promising, and - for normal viewing magnifications, remains useable up to ISO 12,800.

At lower ISO settings the A55 is able to resolve almost the same amount of visible detail as the Canon EOS 550D, which is currently the highest resolution camera in its class. Dynamic range is excellent too, at almost 9EV, which matches the best of the competition.

In use, the A55 feels like a cross between a good midrange DSLR and a high-end 'bridge' model, but its focus system and large, high-resolution viewfinder surpass our expectations of both types of camera. Because the A55's EVF is so large, it easily matches most optical viewfinders for clarity.

First Digital Camera

pluggedin.kodak.com reports: [edited]

In December of 1975, after a year of piecing together a bunch of new technology in a back lab at the Elmgrove Plant in Rochester, we were ready to try it. “It” being a rather odd-looking collection of digital circuits that we desperately tried to convince ourselves was a portable camera.

It had a lens that we took from a used parts bin from the Super 8 movie camera production line downstairs from our little lab on the second floor in Bldg 4. On the side of our portable contraption, we shoehorned in a portable digital cassette instrumentation recorder.

Add to that 16 nickel cadmium batteries, a highly temperamental new type of CCD imaging area array, an a/d converter implementation stolen from a digital voltmeter application, several dozen digital and analog circuits all wired together on half a dozen circuit boards, and you have our interpretation of what a portable all electronic still camera might look like.

It took 23 seconds to record the digitized image to the cassette. The image was viewed by removing the cassette from the camera and placing it in a custom playback device. This playback device incorporated a cassette reader and a specially built frame store. This custom frame store received the data from the tape, interpolated the 100 captured lines to 400 lines, and generated a standard NTSC video signal, which was then sent to a television set.

Nikon D3100

Digital Photography Review have published a preview of Nikon's major update to the entry-level D3000.


"The D3100 is built around a 14.2 megapixel CMOS sensor (quite possibly the one seen in Sony's NEX cameras), bringing not only live view but also Full HD video capture to Nikon's entry-level model. This not only makes it the company's second-highest pixel-count SLR (after the D3X) but also makes it the first to offer 1920x1080 movie recording."

Price (Body + 18-55mm VR Lens): £580
