Help! I need some advice manipulating jpg and camera raw images in CS3 on Windows XP because I lack the necessary experience.
I’ve taken some photos of stains left by autumn leaves on a concrete pavement, and I have two problems with the images: first, there isn’t a large contrast between the colours of the brown stains and the grey concrete slabs, and second, the edges of the leaf stains are ill-defined. What I’m trying to do is separate the leaf marks from the concrete so that I can then treat them as separate objects, but I think there’s probably a better way of doing the job than anything I’ve found so far, which is that I’m not having much success with the Quick Selection or Lassoo tools: I always end up with too much or too little selected. Can anybody advise how they’d go about doing this sort of job? A couple of thoughts I had: is it possible to select parts of an image based on colours: in other words, use a colour dropper to select the greys of the concrete but not the browns of the leaves, or the other way round? Is there a technique for temporarily radically changing the colours of the images so that sections become easier to select?
Thanks for any hints you can offer.
