Joe, I might be doing something wrong on the layers...here is what I did:

Original sepia photo is background layer...
I duplicate that and called the new layer color
Used magic wand to select the necklace strap and set feathers to .5
I filled the selection with red.
Set this COLOR layer to Difference which seems to make the picture all black instead of the necklace strap.
I duplicated the color layer again, put it on top, named it color2 and set it to multiply but I still ahve a black picture with the red strap.

what am I missing?

awesome! I think I had the feathers set wrong and im not sure if I was on multiply...I will try again with your suggestions on the hires verson....thank you ill keep ya posted on how I did :)

Joe, she wanted the silver necklace left as is and just wants the chain of the necklace (the black strings) to be red....

is CS3 shipping now? we bought CS2 about 3 weeks ago and were told we could upgrade to cs3 for free, Adobe had me fill out an upgrade coupon but said it will not ship until August!

wow!! Thank you all for the selection...Cassie, the subject in my picture says woof woof woooooof...which means, thank you very much! heheheh

Well I ended up getting the 17-40 and a Tamarac 28-75...the latter for doing some portraits.  I of course will have to skip on the 500mm telephoto for a few years.
 
I will be test driving them this weekend.  Look for a portrait of my daughter, and who knows what else I will come up with on the wide angle.
 
Oh the Tamaron is also a macro, a wide angle macro...most cool..about $300

Thank you all for your input!!!

maybe I will have to buy both! heheheh

heheh I dont want to start a debate, its just I have not used a Sigma before. 

I have the Canon Rebel XTi which is the same as the 400D in Europe.    So the Sigma lens is better than a Canon Lens? 

I have that stock lens, the one I mentioned above...so I wanted something a bit wider for those specialist wide angle shots...  I dont want the wide angle for portraits...I do want a nice portrait lens as well.  I am thinking of a fixed 35mm and a fixed 100mm

My site seems to be up now if anyone wants to look :)
http://www.chuckcondron.com

ya it seems to be down...its hosted with godaddy.com maybe they are having issues, I trust it will be back sooooon

They did not give a reason, just referred me to a faq.  The only thing I can think of is like someone said,  noise, but I use the equipment they refer to, and I didnt have any postwork taht I remember on the shots..   so who knows...  I think I would rather just have my own site, see if I can make it known and just sell when someone is compelled to buy.
 
http://www.chuckcondron.com is the site.  I do not have every shot up just yet, nor a add to cart...just a simple site...

I got word back from the site I tried...Stockxpert.com that my work did not meet their standards.   I uploaded some of my highest rated pics from this site.  Not sure what they want but if they didnt like it then ***k em heheh
 
I do have my own site but am not sure how to get it known.  I made it myself and could easily add the "add to cart" feature, but who would even find it? 

I am timid to send my photos to those sites...some seem to have a group of admins that determine if they meet their standards.  I think if I was rejected, I could plumate into a deep depression heheh
