I noticed one picture in the extraordinary challenge that looks like the background was converted to grey scale. Isn't that against the rules for basic?

yes it is.

no effects filters may be applied to your image, with the exception of Noise and Gaussian blur, the two of which are allowed. Any filter permitted by this rule must be applied uniformly to the entire image. Selective application of the filter is prohibited.

can we safely assume that it will be challenged?
 06/30/2004 10:55:09 AM · #4
I have already submitted my request but I hink others should do the same
 06/30/2004 10:58:27 AM · #5
its a shame because I really liked the shot.. Might have been a winner for selective desaturation.

It is very easy to achieve this effect legally within the basic rules.

One DQ request should be enough to get it reviewed, but remember to vote as if it is legal.

Bod... Help me learn... How can you achieve the effect??

You should also try to avoid actual discussion of the photo in these threads. As was mentioned, if you suspect a photo of being illegally edited, submit a DQ request, vote AS IF IT IS LEGAL, and move on ...

Partial desaturation. You can, within the rules, desaturate just one or more of the colors. As long as it is done without any mask it is valid. I did this in the rust-challenge (and got hammered for it. My score increased a lot after I got it validated).



I'm not saying this is the case here - it might well not be. But as always - remember to vote as if it was valid.

You can probably desaturate the sky for instance, if that is the only blue area in the image.

Found the image (I think) and although we're not supposed to comment on ongoing challenges of course, I would bet my money on that image being very valid (and in my oppinion pretty clever at that).

Think for a while, how it could be done.. See? Got it? Clever..

Now I am really confused... I am not speaking about any picture in particular but how can you use partial desaturation and comply? Isn't "partial" the oppisite of entire? Unless the effect was created in the camera how is it possible for partial desaturation to be applied to the whole picture. Please bear in mind I am new to photography in general and I am trying to learn.

If you had a photo of a red car against a green (grass/trees) background you could, in photoshop ...

Open the hue/saturation adjustment.
Use the dropdown to select the green colour range.
Reduce saturation to -100%.

This would desaturate the greens, but have no effect on the red car even though you have applied it to the entire image.

I'm sure there used to be a tutorial on this? Should I write one?

Thanks Bod. I understand how to do that and I thought about it. I can see how you can achieve that result with your entry in rusted. I dont think that thats the case with the photo I have in mind. I will be very curious to see if the image can be obtained by using that approach. I think the approach you used is selective desaturation of specific colors which you applied to the whole picture.
Oh and by the way I thought your shot was very cool..

Unfortunately the rusted photo belongs to Donatien, not me!

I'm not sure that's the best example for this discussion though. Here's one ... which just happens to be a red car on a green background ; )



This was my alternate for the extraordinary challenge and so is processed completely within the basic rules. I simply desaturated all the colours which don't appear on the car - although you will notice that the yellow sticker was effected.

Thank you (the rustie was mine, as you probably noticed by now). I answered your original question without looking for the image first, so I figured it might be the case - but like you say, it wasn't this time.

I don't want to get into discussions about an image in voting, but I think you'll have to concider that things are not always what they seem. There are for instance many pictures on this site taken with a monitor as a background, to achieve "impossible" effects in basic editing. You see what I'm getting at, right?

If there isn't one, yes, please do. Ann

Besides the Tutorials, there's also a batch of "How'd They Do That?" articles on specific photos. This very early one kind of covers the same effect, only used in reverse (only the main subject desaturated), but the general principle is the same. Also, if you do a forum search for "desaturation" you should end up with several threads which discuss this and how to do it.
