This text is an analysis of a video I did some months ago how to process photos of our Milky Way in RawTherapee. You can find the picture here . The photo was taken by wiegemalt.

Editing: Step 1: Fixing lighting The first thing someone notices when opening the picture is the extreme noise due to high ISO used (1600 - check the picture on the right). The first thought is to de-noise the picture, however, if you do that you are going to loose the details of the night sky. The main reason for the high noise is the additional exposure Rawtherapee adds when the 'Auto' button is pressed. In particular, the RT adds +2.4 EV to equalize the picture. This is Wrong! What we want is to keep the noise down and at the same time bring the stars up. That's why we are going to play with the Tone Curve of the RT. To adjust the light properly we increase the cont...

At the very early stage of the career, the developer should learn the basics: how to structure his code, how to write small functions, what is desirable and what is not. I can suggest two books for people starting in software development: "Code Complete: A Practical Handbook of Software Construction" from Steve McConnell and "Clean code" by Robert C. Martin. The first one presents the basic rules on how to write good code, and the second one explores in greater depth the best practices for writing good code. A also strongly suggest to learn about the design patterns that exists in the software development. There are two well known books, the Design patterns : elements of reusable object-oriented software by the gang of four (Erich Gamma,...

Every summer I visit the old city of Rhodes in Greece. Every time i feel amazed from the liveness  of the city. People everywhere, shops, restaurants, and of course bars. Full of night life, crowded from young and old people. Here are some impressive photos: Rhodes, Greece, entry of the old city. Sokratous street, old town, Rhodes, Greece during the night. Full of life! Old medieval castle of the old town in Rhodes, Greece. Impressive also in the night. Old town of Rhodes, Greece view of the clock in one of the many small streets. Even in the smallest streets you can find open shops during the summer. In Rhodes, Greece.
