Color management in Firefox
I’ve bought ColorHug to make color profiles for my monitors. ColorHug is a great device for the price and it works without problems on GNU/Linux. Using it together with dispcalGUI I could easily create the color profiles. Making a color profile is one thing while applying it is another problem. My experience with color management […]

Sensor cleaning
My digital camera sensor got dirty enough and it was no longer possible to clean it just by softly blowing air to it. So I looked for a more powerful cleaning solution. After some searching I decided to try Pentax Image Sensor Cleaning Set O-ICK1. It looked simple and didn’t require any liquids. Does it […]

Is it safe to use old flashes on modern cameras?
Sometimes the possible consequences of connecting old flashes to modern electronic cameras (both digital and film) through hot shoe are discussed. The problem is high voltage (up to at least 300 V) of those flash units on their contacts, exceeding the standard limit of 12 V. I’ve never heard about a destroyed camera from direct […]

Printer calibration
Some time ago I’ve finally managed to get my Epson R220 printer somewhat calibrated. Standard Gutenprint drivers suffer from strong green cast on this printer and I wasn’t successful to get it corrected directly in Gutenprint. Trying to play with the driver color settings has led me only to other problems, replacing one kind of […]

Scanning films with flatbed and film scanners
Film scanners are often claimed to be superior to flatbed scanners when scanning 35 mm films. The harder thing is to find actual facts supporting such claims. Actually it’s possible to find samples suggesting there is no significant difference between the scanners. And even Minolta was able to find the only relevant argument for film […]

Damaged films
One of the main advantages of digital photography over film is that all the process is in your hands. With film at least its development is usually left to a laboratory. And this is a problem, I’ve experienced a lot of troubles with it: scratches, sticked garbage, fingerprints, even exchanging my roll of film with […]

Scanning software
Scanning software should deliver maximum information in the best possible form. It’s not necessary to avoid further processing, but it’s important to keep it possible and to perform processing steps that can be made automatically without losing important information. Choosing right scanning tools is important as mistakes in this process may result in the necessity […]

Scanning print films with Epson 2480
I’ve switched almost completely from using a compact digital camera to using a film camera this year. I scan my 35 mm negatives with a low-end flatbed scanner, namely Epson Perfection 2480 Photo. It is possible to obtain reasonable results using that cheap device, but it’s not easy. I’ve been learning a lot during the process […]

Film sensitivity
When I scanned photos from the Fuji Superia 400 film I was very unhappy with grainy shadows. The grain seems to be really worse there than in brighter areas even when considering the effect of higher noise visibility in dark areas. I couldn’t get rid of it even when I tried to significantly overexpose. By […]

Moonlight photography
I’ve finally managed to process my photos from the last winter. You can look at samples of my photos taken under moon light. They are not good photos but they show how moonlight photography can look like. Note the photos are somewhat shaky because I forgot the remote control at home and had to hold […]
