Again higher ISOs and the colour skews they seemed to enforce made things trickier still. detail around 50) is good for color noise reduction, but leaves luminance NR behind, so Neat Image. Of the eight “usual” presets for white balance on offer (daylight, cloud, tungsten, etc.), I found none very inspiring and resorted to using the custom white balance setting when lighting issues became tricky. I have (among others) Sigma SD14 and I now also GH2. The auto white balance setting performed okay in daylight but encountered problems indoors. Sigma has gambled a bit by adding JPEG shooting to the SD14. Layout and working of a photodiode array.

JPEG files offer the same resolution options in basic to fine quality, plus a super-high, interpolated resolution of 4608 x 3072. mented into Sigmas D-SLR SD9, SD10 and SD14, as well as into Polaroids x530.

And, at the extended ISO 1600 mode, it’s very poor indeed.Īdditionally, the higher the ISO the less accurate the colour becomes with greens and reds suffering most. The SD14 produces X3F-RAW images in high, medium and low resolutions (2640 x 1760, 1776 x 11 x 864). Noise issues are not significant at ISO 100 and just starting to appear in shadows at ISO 200 by ISO 400 it’s noticeable with evenly spread noise speckles and, at ISO 800, noise becomes obvious. Switching to high quality JPEGs is fine, though jaggies become evident but go higher to the double-the-resolution SuperHI boosted mode and you loose detail as well. Use the lossless RAW (but frustratingly there’s no RAW+JPEG mode) mode and you’ll be okay.

Once you build a set of noise profiles for a specific device yourself or download a ready profile set for your camera or scanner from the profile library, you can use the the Auto Match function in Neat Image. However, shooting in the wrong mode can compromise the sharpness and detail it can record. The user guide can be opened from the main Neat Image window by pressing F1 or downloaded separately.

In terms of image quality, I had Sigma’s excellent 17-70mm F/2.8-F/4.5 wide-zoom lens and this is an excellent optic indeed.
