Fine Art Media vs Conventional Media

There is a distinct difference between conventional photo grade paper and fine art paper. Fine art media is not only more substantial and richly textured, it's long-lasting. Fine art media is typically made from 100 cotton (except canvas which is usually 50 cotton & 50 polyester). It's also acid-free and buffered against atmospheric acids. (Buffering neutralizes acids in the paper or environment using an alkaline substance such as usually calcium carbonate.) The media will last for centuries...

Hard to Meter Scenes

Occasionally it's not convenient or even possible to meter a scene. Neon street signs, spotlit circus acts, fireworks, moonlit scenes, and many similar situations are all difficult and sometimes impossible to meter. In these cases, it's easiest simply to experiment, using the exposure compensation control on your camera (see Topic 0.0). After taking a picture at the suggested exposure, you use exposure compensation to take other exposures both lighter and darker than the suggested settings....

CMOS image sensor facts may drop

Here are some things you might like to know about CMOS image sensors CMOS image sensors can incorporate other circuits on the same chip, eliminating the many separate chips required for a CCD. This also allows additional on-chip features to be added at little extra cost. These features include anti-jitter image stabilization and image compression. Not only does this make the camera smaller, lighter, and cheaper it also requires less power so batteries last longer. It is technically feasible but...

Sensitivity

The speed, or sensitivity, of a silver-based film is given as an ISO International Organization for Standardization number that appears on the film package. The higher the number the faster or more sensitive the film is to light. If you've purchased film, you're already familiar with speeds such as 100, 200, or 400. Each doubling of the ISO number indicates a doubling in film speed so each of these films is twice as fast as the next fastest. Image sensors are also rated using equivalent ISO...
