There are several web pages and YouTube videos extolling the advantages of using Photoshop’s LAB mode for colour correction, but the following are a couple of tweaks that could be incorporated in every photographer’s workflow, and are suitable for almost every image. LAB level and curve adjustments are the best way to make colour alterations, …
[nextpage title=”Introduction”] Sony Ericsson K800i mobile phone v Canon 350D v Canon 5D Mark II [published july 2006] Everyone needs a day off. What better to refresh a palette jaded by the testing of $2000 optical exotica than to put a free camera phone through its paces. Seriously, though, the 3.2MP Sony Ericsson K800i is …
Many professional and amateur photographers have abandoned Canon lenses in favour of Olympus, Leica, Zeiss (and even Nikon!) lenses for their Canon digital cameras. Given the fact that a (frequently expensive) adaptor is required, and that the user is robbed of autofocus and required to deploy stop-down metering, some have rightly wondered: is it worth …
Photography is part art, part science; choosing and using lenses similarly blends subjective and objective views. The ultimate merit of a lens is arguably best measured by its ability to become invisible, to deliver unadulterated reality to the film plane.

You may have noticed and/or been confused by the convention used here in which lens performance is addressed by ‘Zones’ rather than the more commonplace ‘centre, edge and corner’ designation. At the risk of treading on the toes of Ansel Adams of Fred Archer, I feel that this, more empirically explicit, system is helpful. Here’s …
12mm Rectilinear v 15mm Rectilinear v 16mm Fisheye How useful is that Sigma 12 -24mm! A bit squishy, flarey, and prone to wild sample variation, but uniquely useful for interiors and landscapes – and uncommonly free of Sigma Jaundice. How to scratch the upgrade itch, then? I would suggest that the Canon 14mm L and …
