Viewing images/photographs on a computer monitor

This site is optimized for monitor resolutions of 1024x768 or larger. Scrolling may be necessary to view entire photographs if you your display is set below this resolution.

Contrast and brightness

In order to view my photographs with the contrast and brightness I have intended for them, adjust your monitor's contrast to 100% and then adjust the brightness until you can see each individual section of the gamma bar (that is located in the top section of each page), including the darkest zone on the left. By doing this should allow you to view my photographs with optimal contrast and brightness.

Color and gamma

Color rendering is quite tricky, as only few use calibrated good quality displays; in general you get more value for the money, and Apple Macs have inherently better color rendering (support for the display ICC-profiles and more accurate factory profiles) than PCs, laptops of which are usually the worst. Furthermore, only few browsers (e.g., Safari) support embedded ICC-profiles in images. To solve the latter dilemma, the Fine Art photographs shown in these www-site are converted to sRGB (1968) profile, which is the (old) default colorspace of PC and other (usually uncalibrated) computer equipment.
In practise, what you see on your display is due to variations in brightness, contrast, and color. Macs and PCs operate in entirely different "gamma" ranges, althought today the industry is working to make the differences smaller. Images that look right on a normal Mac (1.8 gamma) will look dark on a PC (ca. 2.2 gamma). In other words, a photograph balanced for a PC will look washed out on a Mac. My photographs are adjusted in a Mac environment but using 2.2 gamma, and the website is built for the Mac, so it runs best with Safari, Mozilla and Netscape, but worse with the MS Internet Explorer, which also has the worst CSS-support.

Metamerism

In everyday life, how we perceive the colors (spectrum thereof) depends highly on the ambient light (e.g., the color temperature (K) and the spectrum of the light source). Regarding printed photographs, under tungsten bulb-viewing (especially strong halogen lights) they become yellowish and warmer, but under normal fluorescent light they become bluish and cold. Similarly, also monitor displays are severely affected by ambient light and depending on the type of the display (CRT/LCD). Also, the overall brightness of the room affects: images appear lighter as the room becomes darker. what is more, CRT monitors have a warm-up period (up to a half hour) in which the screen (and the images) steadily becomes lighter.

Web vs. in person viewing

Viewing Fine Art photographs over web is still a struggle at best. The images are not viewed at high resolution on calibrated high-quality displays in well-controlled surroundings. Yet, I hope that they give you, the viewer, an anticipation of what the actual large-format prints are like - sure to leave you speechless.


Thank you for viewing my work.
