New Cameras' Support

Minor Changes and Bug Fixes

Color is a Slippery Trickster

Origina ARW from SONY a6500: embedded JPEG vs. render using correct camera profile

“How do you know, when you think blue — when you say blue — that you are talking about the same blue as anyone else?"

Christopher Moore, Sacre Bleu: A Comedy d'Art

The goals of this article are twofold: the first is to demonstrate that out-of-camera JPEGs, including in-camera previews, can’t be implicitly, with no checking, used to evaluate color (as we already know, the in-camera histogram is misleading, too). The second is to show that it isn’t necessary that the camera manufacturer-recommended converter be specifically tuned to match the out-of-camera JPEG.

When In Doubt, Bracket!

Golden Tree. Exposure Bracketing

On any photographic forum, it doesn't take much effort to find old or new discussions on how to set the “proper” exposure while shooting, and even what exactly “proper exposure” is. The question of setting exposure was and is one of the most commonly-discussed topics on forums and blogs

Often, an experienced professional photographer will, upon hearing the question of how one should choose exposure while shooting, respond that you should “Bracket your shots when the lighting conditions are complex. Or, even better, bracket all of your shots. I do it all the time.” That’s because problems with exposure are not something that only a novice can encounter.

Color Differences Between Cameras

RawDigger. Placing a Grid

Quite often, when a new camera emerges on the market one heavily-discussed subject is if the color it records is the same, better, or worse compared to a previous model. It often happens that the color is compared based on the rendering that some RAW converter provides. Thus, an unknown variable, that being the color profiles or transforms that a RAW converter uses for these particular models, comes into play. Yet another problem with such comparisons is that they are usually made based on shots taken with different lenses, under different light, and with effectively different exposures in RAW (while the exposure settings may be the same).

Let's see how cameras compare in RAW if the set-up is kept very close to the same and the exposure in RAW is equalized.
