A few black and white experiments

In the same picture series as for the previous posts, some of the shots were not really convincing on the colour side of things… But for a few of them that showed nice geometrical patterns, I decided that I would try to convert them into black and white.

The first results of the convertion are the following:

Un toit à Saint-Malo

A roof at Saint-Malo

Un rayonnement du passé

Technically, nothing impressive is involved :

  • a mix between Red/Green/Blue chanels performed from the RAW file (with UFRaw)
  • some tweaking on the contrast as well
  • small sharpness enhancement
  • a quick framing

Of course there is much more information about this on a MeetTheGimp podcast.

When posting one of my pictures, I usually say that some post-processing was done. This is nothing but very classical stuff, that I believe are common to most photographers.

However I’ve been advised to give a glimpse of what those modifications were. And that’s why this post will explain and illustrate, for a very simple case, how, starting with a picture coming out of my camera, I get one that suits me enough to post it here.

Île et sillage au large de Saint-Malo (version finale recadrée)

Island and wake in front of Saint-Malo

Long story short, the post process I usually do, and that I will show here have basically two purposes:

  • improve color and contrast
  • re-frame the picture
