From time to time, while complying with the basic editing rules, I see black and white photos with a colored object in it. For example, //www.dpchallenge.com/image.php?IMAGE_ID=287532, and //www.dpchallenge.com/image.php?IMAGE_ID=289348
I'm sure I can achieve the same thing by "spot editing". Can somebody explain to me how photographers did this under the basic editing restrictions? Thanks in advance for you help. |

helped you post the thumbnails
Under BASIC EDITING:
you cannot spot-desaturate colours, but can selective desaturate colours
Under ADVANCED EDITING:
you can spot-desaturate AND selective desaturate colours
So under Basic Editing, the post processing is about removing all colours except the intended one. This is usually a hit and miss thing, and if you are lucky, you get what you want. Like example, the tombstone photo above. It so happens there are nothing else in the photo with that shade of red, so when all colours are removed, that one shade of red remained on the flower.

What about desaturating everything with an adjustments layer and them mask the areas you want in color for basic editing?

I'd be carefull using any layers/masking in basic editing. Here a recent shot where I desat the green and yellow and increase the reds and blues. Just remember in basic editing when you processing make adjustments to the whole image and you will be good.......ace

nope, only advanced cause you're applying desat to a SELECTION rather than the whole thing

| oh, i thought a selection was something made with a selection tool. |

Normally it is, but there's an adjustment named "selective color" that is legal if applied to the entire image at once. It allows you to tweak the rendering of many different color channels. That and the hue/saturation adjustment can be used in tandem to do a pretty decent job of partial desaturation under basic rules.

Thanks - I'll have to watch that. Normally I am a channel mixer B/W guy - but I use masks all the time for a lot of things.

A mask or alpha channel is exactly the same thing as a selection which has been saved -- make a selection and save it, and then look at the channels pallette and you'll find it there.
Converesly, create an alpha channel and paint something on it, then go to the Select Menu and choose "Load Selection" ... |

Yeah I know about selections being saved in channels, but masks on adjustment layers - I don't understand why that qualifies as a selection.

Well when you have a mask on an adjustment layer and have that layer selected it shows up on the Channels palette as an alpha channel. Btw, masks by their very definition are selections.
