RAW or JPEG?

The electrical signal generated at the time of shooting by the matrix of a digital camera enters the camera processor as an array of digitized, but not yet processed or, if you like, “raw” data. This data is then either recorded without further processing on a memory card in the form of a so-called. RAW-file, or pre-processed by the camera processor, which forms a full-fledged image on their basis and saves it in JPEG format.

That is, even if he worked on his own health, but he also puts it all on the Internet, insistently demanding attention and compliments. Having received them, he begins to drift, but not received Continue reading

RAW or not RAW
The RAW format will never be accepted. Never means “never”, and not “not in the near future”. Old photographers remember that before its appearance there were several formats that, although…

The fight against laziness and time management for the photographer
Let's not forget that many photographers are now giving their clients photographs in indecently long periods. I will not quote wedding clerks who give out albums after 9 months, when…
