There are a bazillion (at last count) ways to convert to black and white, but one thing I like to do is insert another hue/saturation adjustment layer BELOW the desaturation layer.

So, create a new adjustment layer, add a hue/saturation layer, and then just click OK without making any changes (your image still looks the same so far).

Then create a 2nd hue/saturation layer, and drop the saturation to 0, as in your tutorial (or whatever other way you want to change to black and white), and click OK… now you’ve got your B&W image.

Now go back down to the 1st adjustment layer you created and open it up (double click the thumbnail on the layer palette)… now slide the HUE slider around, and you’ll see the tonality of the black and white image change…. it’s sort of like using a lens filter with black and white film… you can use the different settings to accentuate different parts of the image. =)

You are absolutely right! Some of the Canon digital cameras have this feature. Don’t know why they do not advertise it more; a quick search on the Web should convince them that it is a really popular feature.

As you also mention, it is more flexible to do it in post processing, allowing a specific object (or part of an object — not necessarily ALL the red objects, for example) to be chosen, or as in the sailboat example, just one object irrespective of colors.

The only downside with in-camera is that you can only specify one colour (although you can add a tolerance), but does mean that if you choose red, then all the reds in the frame will be coloured.

Also cannot do the sail boat example above in-camera.

Try the Saturation slider.

I am a bit of a novice in photography editing. However whilst reading this tutorial I couldn’t help noticing how fantastic the effects of colour accenting were. Is there a way to do this with iPhoto?

Thanks,

Sam
