Hi
Most BW film shooters often use filters (yellow green, yellow etc) to improve the shades of grey (gray) in a BW film.
Shooting without filter makes the image flat ..
SO my question is,
if i convert a COLOUR digital jpeg image in PhotoShop through Image>Mode>Grayscale,
how do i boost the tones of the image (much like using those special filters for BW photography)
thanks for sharing =)
I think you may have confused certain terms and concepts
1 Tones refer to shades/strength of grays between white an black. Tones refer to brightness, lightness, and darkness of the subject, and is determined by illumination.
One does not "boost tones". Tones can be changed by filters.
One can change contrast bewteen tones - increasing the contrast or decreasing the contrast.
Flatness of an image per se is due to a problem of illumination, of little contrast. However in B&W photography, contrast can be changed by appropriate use of filters. By "changing tones", contrast can be changed.
2 My next comments are to be taken with a pinch of salt. I am not a digital guru. But this is how I work my color images to B&W.
As mentioned by cyber_mOnkey, I go to the channels to first see the effects of using different color filters. It may be red, green or blue. Then I go to channel mixer and change to monochrome, select the filter I want to use. Then go to curves to change contrast. And finally, dodge and burn if I think it is necessary.
I do not use layers. I did not find it advantageous to work in layers. Perhaps one day I might change my mind. But I always work with a duplicate, not the original file.
