    Thanks!

    Extraction was done in Photoshop but the process was fully manual. Did not use the extraction tool or any other software. Just paste the original onto the background and then slowly delete the unwanted background in the original picture.

    Agree that the lighting does not match but the main purpose here was to demonstrate the extraction.

    Slowly delete?...wah, surely you don't mean slowly with a brush and paint mask away?..
    How long did it took?

    Nicely done and all it took was 5mins? that is impressive time saving of 40mins per image. I just compared it to what Roy had taken using PS, anyone tried using Fluid Mask?

    btw, where to get a trial copy of Corel Knockout2?

    TIA.

    I tried out the Fluid Mask Demo a while back and found it excellent at removing objects with poorly defined edges such as hair or fur.

    Still no news on the Windows version as yet though unfortunately.

    I visited the Vertus site to check WIN availability and it states:
    Windows Availiable in 2005
    Windows 2000® or above
    Processor speed 750Mhz or higher

    Does this means it's available now, also is Windows XP Pro considered higher than Windows 2000®?

    Still couldn't locate the trial for WIN.

    the hair subject as demostrated by roygoh can be done in less than 5 min in photoshop.
    use select colour range to remove away the unwanted colors/parts..
    will be even easier if u cut the image up..
    imagine

    1st min:
    select top half of image, control + J to duplicate into new layer. select colour range, and delete the sky and tree

    2nd min:
    cut and control J the bottom portion, select the sand colour. use deselect to remove any accidental selection of the hair portion. area select to include the black parts. press delete to clear sand area

    3rd min: press control E twice to merge layers down, use magic wand to select transparent area, inverse the selection, cut n paste into new image

    done..

    *edit :
    Good part about using colour range selection is that if u choose to select blue, and the hair got blue tinge, then it'll select a percentage of the hair... meaning if u dump into say green background, that percentage is visible in the hair.

    Give it a try, play around a bit.. select by colour range is very powerful and very easy. make your own job easier by isolating areas.. or removing similar colours away from the important area.
    sometimes it's easier to select the person then inverse selection to delete the background.

    I would like to see how it performs under truly messy backgrounds. these single colour/distinct backgrounds are just too easy for photoshop..

    Or perhaps like a white shirt from a white background? or face from a beige coloured wall, or hair from black/dark background. is it any easier? These are the ones which would take me much longer to extract using photoshop..

    Nice and cute son u got there Roy..
    heh anyway if me, I'll use colour range to select the hair colour, use normal marquee tool to add in the portions of the head not selected (leaves the spikey edges), then use magnetic lasso to select the rest of the face and body. should be done in 5 min max.

    Photoshop is good..

    Since discussing on photoshop can you show me How to replace part arms of a model with her good arms from other photos. Or blur face replace with sharp focus face from other of her photos.

    I do not know how to do it. Advise is appreciated . Thanks
    Think of concepts and work towards it.

    starting a new thread on this topic might be more useful for yourself and others.

    the current topic is on extraction not photoshop.

    Thanks.

    Yeah, it looks like they're still working on the Win version. I keep checking back there cos people I know want to try it but don't have a Mac. Fingers crossed for something soon.
