Sigma SD1 DSLR Review
George Schaub  |  Sep 30, 2011  |  1 comments

The SD1 is Sigma’s new flagship SLR system. It uses a brand new sensor with Foveon technology and a nominal resolution of 14.8 MP. This means that the camera is able to record RGB information for every single pixel. Standard digital cameras use sensors with the “classic” Bayer pattern, which means that every single pixel detects only one color information (red, green or blue) and then must undergo color interpolation.

Sigma’s 24-60mm f/2.8 EX DG
Wide Zoom For Film, Moderate Wide Zoom For Digital
George Schaub  |  Mar 01, 2005  |  0 comments

Note the "EX DG" appellation in this new Sigma lens. This signifies a lens that you can use for both film and digital photography, as opposed to Sigma's "EX DC" branding, which can only be used with digital SLRs. The difference is in the image circle each projects. Use a "DC" lens on a film camera and you'll have serious...

If you enjoy exploring the fascinating world of close-up photography you should consider a ring flash as an essential part of your creative kit. A ring flash mounts around your taking lens and eliminates problems associated with standard shoe-mount flash and even off-camera flash, mainly the inability to down-angle the...

Sigma’s Fisheye Duo; The Sigma 4.5mm f/2.8 EX DC HSM & 10mm f/2.8 EX DC HSM (Motor-In) Lenses
George Schaub  |  Aug 01, 2008  |  0 comments

If you ever want a unique point of view try a "fisheye" lens. Like looking through a door peephole (which in fact is a "fisheye" type) this order of lens sacrifices linear correction in favor of a very wide angle of view. Originally made for creating "full sky" images when pointed straight up, they had long ago been adopted by photographers for...

SilverFast Ai Studio 8 Scanner Software Review
George Schaub  |  Jun 07, 2016  |  1 comments

Digital Ice and similar dust and scratch cleanup tools for scanning color negative and non-Kodachrome slides was a boon for those looking to archive/digitize their film files. This software/hardware solution worked with numerous scanners by isolating the offending dust and scratches on a separate infrared channel that it then dumped when the final scan was made.

Software Updates And Opinions
George Schaub  |  Jun 22, 2011  |  First Published: May 01, 2011  |  0 comments
Image processing has always been an important facet of photography, even in these post-film days. Indeed, even working from film, most photographers now go the scan route so that all images get poured through the digital funnel as they make their way to print and online. While we often run processing technique articles that concentrate on Adobe Photoshop, the reviews here feature other products that pose an alternative to that most impressive program and that might just handle many of your conversion, manipulation, and editing needs. It is rare these days that one software package can do it all, and many exciting programs are available that offer unique ways for you to work your images.
