Discussion
I spent saturday at a car show/drag racing event, it had a kind of "Max Power flavour" to it so not normally my scene, but among the myriad of modified Toyotas, Nissans and Volkwagens some pretty nice machinery turned up. Besides it´s impossible not to be impressed by some of the drag racing cars - the noise and the barely believable acceleration off the line is quite an experience....
Anyway, apart from sunburn
(it was the hottest day of the year so far up here in Sweden) I got some pretty nice captures if I do say so myself

I've always wondered, how do you do that Black and white image with a spot of colour thing?
It's actually very easy to do:
1 - In Photoshop make a selection of the part of the image that you wish to keep in full colour.
2 - Invert that selection.
3 - Go to Image -> Adjust -> Hue/Saturation, drag the saturation slider to zero and Bob's your uncle!

I'd take issue only with these comments:
then...
That bits a right bugger! To get it perfect takes a lot of time and a large monitor in my experience. I wonder if there's an easier way than tracing the outline using one of the lasoo tools?

You're right Steve!
Maybe I should have written that in this particular case it was very easy. The red bit of the light is so well defined that it's no probs to make a selection with the lasoo.
If your trying to make a selection of a leafy tree for example then it is indeed a right bugger!
The best option imo for making more complex selections is to use the Pen tool and create bezier curves which gives you much more control to fine tune the selection. When you're happy with the path just save it and choose "create selection from path".
It can be a bit tricky in the beginning though if you're not used to drawing bezier curves, but it's extremely useful once you get the hang of it.

Too true, total nightmare in some cases. I found drawing with the mouse was not getting me fine enough definition, it would keeps jumping by quite a few pixels. I've cured this by treating myself to a small Wacom tablet (Volito) which also comes with a mouse and cost me less than GBP 40 from dabs (inc delivery). The pen makes image editing so much easier and at GBP40 it doesn't break the bank.

A simpler way: make the image monochrome and use the history brush to restore colour where you want it.

Those are some fantasics pics! Did you do them all with your method? Never thought of doing it with the history brush!

Hi KITT and many thanks

History brush works well for convex objects, and you reduce the brush size as you get closer to the detail; if the area concerned has straight/ish lines I use the polygonal lasso instead, either by the method already described or by using the area as a mask and brushing over it.
Another method, which works very well sometimes (I think it would be good for the tail light one here) is to go to the Select menu, then Color Range. You can then choose the colour on the screen that you want to select. Holding down shift will allow you to choose more than one colour. then adjust the slider in the dialog box to get the correct tolerance so that you have selected what you want. Then press OK. It doesn't matter if there are other areas of the photo that have also been selected, as long as the bit you are interested in is not touching any of these other areas. You can get rid of the unwanted bits by doing a negative selection (hold down alt whn in the marquee/lasso tool). Then invert the selection, and desaturate.
Hope that makes a little bit of sense...

Thanks Magnus, i'll have a play with some piccies later

Simpo, I'll also have ago with your technique aswell.
Only so much I can do with PS 5 Limited Addition, and laptop touchpad
