dear nt,
i have an image of a person cutting metal. i would like to make the image greyscale EXCEPT for the sparks. i would like for them to retail their original color. what are some ways I could go about this? channels? 3rd party filters?any help (that works) could warrant some brew in the minnesota area.
thanks,
j

Uh ... layers and some work?

I'd do it with two layers - one greyscaled, the other masked and edited to only show what you want.
If, however, there were lots of background artefacts interfering with the sparks, I'd probably greyscale the image and manually colour a layer above, with 'the best looking colour mode' set.

thanks all. i forgot about color selection and stuff. i'll try and see if i can upload the image via the firefox ftp client. i am at a place that also blocks flickr :(.
thanks again. nt really does have its perks!

You could just enter it as the source image in tomorrow's PSB and see what you get back :)
..Probably nothing useful, of course, but hey.

make a selection of everything but the sparks, then layer>layer mask> desaturate
- barbtastic0
the extract tool [under filters] is made especially for this purpose
- jaylarson0
desaturation and extraction sound like good options. but "the best looking colour mode" ... i have G for gulible written on my forehead... i searched google for the phrase.
what didja mean nairn by manually coloring a layer?
as for uploading it for friday's ps battle. count on it! the image has some nice areas where the sparkes are bouncing off of. and being last weeks' (or the week before's) champ, i'd be intersted in what you come up with....

I meant I might consider simply gresycaling the source image, but before I do, take a dropper of the spark colour (blue, presumably) then, add another layer, paint over the sparks in blue then go through the layer options 'til I find one that looks right.
tbh, it's hard to say without seeing the image. the above method would suck if there're gazillions of sparks, so i'd probably use a combination of the above method with "select colour range" and a mask.
the vodka i've recently started drinking is kicking in, so i'm not sure if this makes sense.
If you post the pic tomorrow, i can look at it properly, if you like.

thanks. yep. there are a gazillion sparks. but hey, they are paying me and i got tunes.
enjoy the vodka.
peace.

jaylarson... using 'extract' to isolate the sparks from a dupe layer will save you a lot of grief
- jaylarson0
extract.
is that any different than creating a mask over the layer to expose colored sparks?
do you have any links to tutorials or any other info barb?

sparks are so 2001

Extensis Mask Pro

VV, thanks. that's what i was thinking of. i will bring the image home and workie on it!
the mask is coming along as well. slow but working. the tricky part of this image as from the angle, the sparks illuminate the metal behind the saw. it makes extraction difficult.

masking apps are awesome, it finds the lines and you fill them in like paint by numbers
in ps you could dupe the image and use find edges to build up your mask but the software is tighter and somewhat quicker
:D
