The QSN file. I shutter to think what would happen should the QSN fall into the wrong hands.
Therefore, we have hired 3 very prestigious detectives to guard it.
Sheerluck Holmes.
The Pink Panther's cousin, The Cyan Cougar; and James's indefatigable brother, Treasury Bond.
We wish them luck!
The qsn files are somewhat misunderstood adjuncts to Qimage Ultimate's performance.
Let me set up a situation which is subtly handled by Qimage in a way you never knew.
I have images sent to me from folks who wonder what settings will get the best from the image from their "new" camera which has triple the resolution of the old camera. They look awful, noisy, grainy and soft.
QSN to the rescue.
To simplify, the qsn file is a custom file of 2 essential presets + some non essential ones.
Preset 1 is pre-sharpen. Based on the emails I get, it needs some explanation.
1) Raw images are inherently soft. They come that way. We use a preset of DFS sharpening ( a little) just to get it looking reasonable.
This is applied to all your shots from that camera.
Think of it as putting on your socks every morning.... just looks presentable; that's all.
When finalizing your processing in the Editor, you can apply the final touches of DFS if needed.
Each image is different. Contrast, lighting, content, and inherent noise, all different from shot to shot.
2) Camera noise. Usually worsened when too many pixels are packed on to a too small sensor.
We have Granular noise and Chroma noise.
The adaptive Noise reducer in the qsn file is one of Mike's wonderful applications that goes unheralded.
The video hopefully will explain it all. So I wont go into detail here.
My Canon 20D and my 50D are excellent examples of more pixels, more noise with it.
Remember to make full screen for HD, and enjoy
