UK prices – a steep climb ahead

This is a very short post. I’ve been talking to a few directors of importing companies in the UK over the last few days, as people return from holidays which many in the photo industry take in early January. The word is this: while prices right now, and at Focus on Imaging 2009 Feb 22-25 show, may remain low and even be cut to liquidate existing stock, the rises which will hit us in mid-2009 will knock the wind out of you.

Sekonic's camera calibration

The Sekonic Digitalmaster L-758D meter offers the solution to variable ISO/EI ratings, and apparent sensitivity and contrast curves variations found in DSLRs. With a USB interface to link it up to a PC/Mac calibration program, the L-758D can remember three different cameras, two types of lighting (ambient or flash) and two measuring methods (incident or reflected) plus a range of ISO values for each of the cameras. There are twelve basic ‘profiles’ that can be stored, and within each profile a range from ISO 3 to ISO 8000.

Tilt-shift with full frame DSLRs

After just a short while working with full frame, high resolution DSLRs the need for tilt lenses has really come home to me. Most lenses deliver their best results at fairly wide apertures like f8, it’s easy for detail to begin to look soft and lacking impact if you are forced to stop down to f22 to get everything sharp. Tilt adaptors and tilt lenses solve the problem. This article is repeated here after originally appearing on dPhotoexpert (and similar instrument images, in my first D3X test report for the British Journal).

Canon EOS 5D MkII, Nikon D3X, and Sony Alpha 900 compared

This set of full size shots was taken with the still life left set up, because the Nikon and Canon cameras were not here at the same time. The report originally appeared in December 2008 on photoclubalpha. It compares the A900, 5DMkII and D3X using the converters supplied by the makers – Image Data Converter SR2, Digital Photo Professional, and Capture NX2. Each small image in the article can be clicked to open a Level 10 quality full size JPEG – beware, the largest is over 13MB of data.

Exmor 'R' debuts in Handycams

Sony’s new back-illuminated CMOS sensor design makes its first appearance – along with technology borrowed from the Alpha system – in a new HD Handycam video model, the HDR-XR520VE/500VE. Hopefully presaging future DSLR developments, the range also includes models with built-in GPS tracking to record the location of shots as you film.

Expodisc white balance with the KM Dynax 5D

The custom white balance function on the Konica Minolta Dynax 5D could not be quicker to use; turn the left hand top dial to the custom symbol, press the button in the centre of the dial, press the shutter after aiming the camera at your white or grey target. Custom WB is now set until changed with a new reading, or returned to fixed or Auto WB.

Sony Alpha 900 and Nikon D3X raw file noise comparison

Like Mike Johnston writing in The On-Line Photographer, I’m aware that any attempt to line up one or more cameras and show comparison images or make judgements is on to a loser from the start. And any webmaster who puts an external link in the first half dozen words of a new post is losing the plot too! But here, for what it’s worth, is the first line-up of results processed using the same software from A900 and D3X uncompressed raw files converted without sharpening or noise reduction.

Full frame demands inclined planes

After just a short while working with full frame, high resolution DSLRs the need for tilt lenses has really come home to me.
