Our Silver B&W Camera is for B&W photographers. It gives tools to control how color is transformed to a grayscale image.
(And of course you can take great color photos also, so even if your not in to b&w photography you will like the rich features of Silver B&W Camera)
Image above has five quick selection buttons at the bottom of screen to set the mode of the camera.
At left is colorful button for color photos.
Next to it is a grayscale button for very natural looking b&w photos. It approximates the way human eye is sensitive to different colors.
In the settings you can select the startup mode to be color mode or this natural b&w mode.
The last three buttons select a single channel of color and uses it to create the b&w image.
Digital camera is sensitive to three colors – red, green and blue. So the sliders at the upper right corner correspond to these colors (as do the quick selection buttons). You can adjust each slider between 0 and 100. Zero means that this color is ignored and all other values indicate the relative amount of that color in the b&w transformation.
The highest value color looks lightest and the lowest value color darkest in the transformed image. So if you set red to some value greater than zero and the green and blue to zero then pure red is transformed to white and pure green and blue to black. (You can also set this mode by touching red quick selection button.)
Real targets you photograph in real lightning conditions never have pure red, green or blue colors so red would not be really white but instead have somewhat darker shade. Green and blue would not be absolute black but somewhat lighter shade of gray.
Please note that the sliders are relative in nature. For example when only one slider has other value than zero then the actual value is not important – all values create same result. Also if two sliders have non zero value and they have the same value it is not important witch value it is – all values yield the same result. And finally if all sliders have same value, then the result is same regardless the actual value.
Only exception is when all three sliders are set to zero, then the camera is in color photo mode.
When the non zero values of sliders differ, then they indicate the relative lightness or darkness of that color in the transformation.
And finally, with relative we mean that the values do not actually change the overall exposure of the image. It stays about the same if the scene contains about average amount of each color. If you take a photo of red wall and turn red channel to zero then your photo may look a bit dark. But that is a special case.
