On the other hand I doubt advanced functions like noise reduction, local contrast or edges could be obtained through traditional film photography — and it seems quite easy to fell on the "too much" side of photo editing. There is no doubt that digital files allow much more processing flexibility than traditional silver halide film. But in this ...

One big one you can do digitally that was very hard to do with film is color correction at more than one place along the dark/light range. Unless you were doing very complicated, time consuming, and difficult masking, you could only color correct a photographically processed (as apposed to digitally processed) image at one color point. Color enlargers had ...

As someone who regularly works in other spaces (most frequently Lab) I'd say not to worry about it. Since your rationale for going to another space is to make changes you're expecting that your RGB output will not be identical to your RGB input. Any noise should be well within acceptable boundaries. HSV is by no means perfect and it could theoretically be ...

Both have their usage: HSV / HSL colour models offer a quite useful separation of hue and saturation which is really important for creative operations such as colour correction and colour pickling for instance (as a matter of fact most colour pickers offer a way of adjusting / defining your colour through a HSV colour model). However the way those models ...

I use GIMP 2.8 to correct pictures with lens distortion (Fisheye) effect. This is a free and very extensive software, easy to use. Click in file on open and add the photo that you want to correct. In Filters, click on distortion and choose lens distortion. In "General" you can set the degree of correction with the slider and check in "example" click "OK" in ...

To edit Canon's CR2 RAW files, Canon's Digital Photo Professional will run under wine. The big advantage is that it provides the same results under Linux that it does under Windows. Canon's demosaicing is very good. I have experienced no crashes. Adjustments are available for brightness, white balance, "shot settings" and "picture style", overall contrast, ...
