Colour to B&W......

Postby big pix on Fri Nov 23, 2007 8:10 am

has anyone tried doing B&W using the RAW converter in photoshop......

........ just move the saturation slider all the way to the left, and ajust the contrast, brightness,shadows, exposure sliders to get the result you like...... very quick and very easy

....... from Russell Brown.....

This is how I did my B&W conversions in the thread I posted yesterday (Critique on B&W images). I did them in Adobe Lightroom however, not photoshop.

I slide the saturation slider all the way down and then mainly adjusted the fill light, blacks and recovery sliders. I also adjusted the contrast, exposure as well on some.

A little push on the sharpening and clarity sliders and I was done.

It is very easy but not sure I got it right :cry: I will reply to your post and Leigh's tonight when I get home (thanks for taking the time to reply).

Using the (de)saturation slider like that is a rather crude (although fast) way of getting a B&W result.

There are at least two other ways of getting B&W in Lightroom/ACR:
  • Switch it to greyscale. This is the fastest way, and you can use the grey mixer to adjust the tonality of the coloured areas from the original, or
  • use the separate channel saturation controls to desaturate everything, then use the channel luminance controls in a similar way to the grey mixer.
I usually get the best results from the last option. Although at first it is a bit slower than the grey mixer, in Lightroom you can set up a Develop Preset to speed things up.

Note that adjusting the WB significantly changes the results by changing the colours in the underlying image: for B&W work I usually use a WB that gives me the most colour separation in the image before converting to B&W, even if the colour image doesn't look "correct".

Sooo many ways to get rid of the colour! Another way ....convert to LAB COLOR mode and copy the LIGHTNESS channel in the channels palette. Tweak the levels and bingo!

A whole list of third-party options for monochrome conversion are listed at the top of this page.

Or, you could simply use a B/W CF card...
