2019: A photo challenge
1st of January, time for good resolutions. For me, this year, I would like to take a photo challenge. 52 photos in 52 weeks, this should not be too easy. But 52 photos according to pre-set constraints ; this could be a serious personal challenge. I believe that the rule of the Dogwood 52 week…

Zero digital noise photography
A few years ago I had written about Guillermo Luijk’s technique to remove completely noise from digital photos. We know that this is a difficult task, but his solution is relatively simple: Shot the scene in a correct exposure according to our usual workflow; Repeat the shot now reducing shutter speed by 4 f-stops that…

Photoshop CS4 vs. The Gimp v2.6
Newsrooms are full of weird coincidences. For example, we just learned that two products often presented as direct competition were launched this Fall. To my right, here is Adobe with its boxing champion, Photoshop, loaded up to version CS4. To my left, Linux and its community of free developpers pushing the challenger on the ring,…

One photo, three images
Here is an interesting case (I think) of how I work on the photos I shot. Usually, I think of it as development of the digital image. Like for its argentic/analog counter-part, I have to work a little on the image to make it printable, but I also have to prepare a correct framing of…
