 |
|
Total Newbie here... I am trying to create an effect for a Photoshow I am making on DVD. I have seen this effect before...where you strip all the color out of a picture except one...so it's black and white with maybe just a pink sky, or red flowers. What is the technical term for this effect? Is it easy to create...? Can someone explain to me how. Also can it be done in photoshop Elements or only the full versipn of Photoshop?
Thanks Everyopne! |

you need to isloate the part that you want to make black and white (just one possible way there are others) with the selection tool. PReferably use the select tool to select areas that will still have color then go to select inverse, then using adjust -> hue/saturation you can play around until its black and white (I dont know the exact settings) But you may want someone to do it for you. |

I believe the technique you are thinking of is Chroma-keying or Chroma-key. I am not positive about this as it's outside my normal sphere of work.

It something like this
Duplicate the layer. Desaturate that layer, erase the parts that you want colored.
The bottom layer (coloured) will come thru the erased areas

Can this be done with Photoshop Elements 3? Or must the full version of Photoshop be used?
Thanks! |

This can ONLY be done in Photoshop 5.0 ,6.0, 7.0, CS and CS2 because they have what is known as ALPHA CHANNELS, it would be very, very hard to do what you are talking about in PSE2, and 3 because they do not have alpha channles you are able to work with.

Yes. You can do this in PS Elements 3.
Open your image. Make an Adjustment Layer for Hue/Saturation. Move the saturation slider all the way to the left to make image bw. The adjustment layer has mask (little white box on right). Paint with black brush to let color parts show through.
Use your Help file for a more detailed explanation. |
