I've read several tutorials but still remain unclear as to how I would go about creating the effect whereby a colour photo is made black and white all except for perhaps an entire bouquet of flowers containing multiple colours. I have read how to make a photo black and white except for one single colour, but our bouquet of flowers would include all kinds of different colours. I guess I could draw around the bouquet using the lasso tool, but I can't see how I could accurately draw around anything using a mouse. Is there an easy way to do this, and any tutorials I could follow. Photoshop CS2 and Photoshop 6 are the versions I use. Any constructive help and advice would be gratefully received.
