Thank you to all the positive responses so far. The pictures I am trying to cut the image from, all have a plain white background. Only a tiny percentage have any small detail (like hair) protruding from the main subject body.
Are the subjects colored? Do any contain brilliant green? (I’m thinking of using the green screen technique to remove the background easily.)
They are commercial products for inclusion in a budget "bargain of the month" type mailshot leaflet. Not absolutly sure what you mean, but yes they are colour photo’s of coloured items, green will be of course in there somewhere, perhaps if you give me an idea of what you mean, I can try a few and see what I get.
After following the thread, it sounds like you want to raplace the background with something else, or *not* transparent GIF for the web.
Yes, I have read you mentioned the background is mostly WHITE and some hair sticking out etc..
In general, it will require quite a bit of Photoshop skill to be able to remove or replace the background. Here is few things you may need to look at.
1. FORGET about the transparent as it doesn’t seem to be the real question you need to be answered.
2. What you really need is MASKING skill, and there are several different methods of Masking. Most people use Channel, combiation with Blending which I don’t use.
a. Masking may take months or years of practicing to master the technique
b. If you have mastered the Masking technique, then I can say that within around 1-2 minutes you should be able to replace the background for "displaying", and similar for small print (like 4×6" print).
For larger print like 8×10" and larger then it may take 5-10 or 15+ minutes depending on the print size and difficulty. And this may require years of experience
3. You should be able to find plenty of videio tutorial about Masking, but most of them is often for showing off, almost useless for real use. But some will give you some general information about Masking, then you will need lot of practice to develope your own skill.
I don’t use the technique (many years ago, I started with similar then got stuck at some point and I had to find other way), not because they are not good enough but because I have developed my very own technique which I have been using for so many years to be able to switch. So, if you want to learn more about masking then I would suggest to get a hold of a Lynda Video Tutorial called Channels & Mask which is pretty good.
Why only pretty good? because even it gives lot more detail and different methods for different problem, but it still only teaching the very basic technique which is good for displaying and probably small print. Yes, it should be able to impress most people, and can be useful for anyone who wants to learn Masking. But it will require more work, more fine-tuning technique for large print.
-My advice
Point your browser to some forum like www.dpreview.com (the Retouch forum) there you can READ (there may be some good forum but many won’t allow unregistered to read or doing anything), and if you register you can POST your question, or post your photo asking other member to share their workflow.
I use to monitor the www.dpreview.com for many years, but I haven’t visted for 3-4 years to know what has been going on lately.
