You've really requested an admin note, as well as put it in your comments?


No Bob, just put it in my comments as with all editing I do. Until now I did not even think that it would be necessary. Actually I still don't as it is not a ajustment of a selected part of the photo.


That's what I thought, and I'm in agreement. Your previous post sounded like you sent an admin note as well.

aside from its legality, I have to say this is one amazing addition to PS. I don't use PS much in my shots but WOW this is going to be one feature I will take advantage of, mostly because on top of great results it is simple to achieve. I am one of those few folks who don't know (or want to know ) how to use layers or curves. But this one I must say I LOVE! It is so much easier than dodging and burning too techniques that take bloody forever IMO.
I hope it gets allowed for challenges. For those of you without PS 8 christmas is coming : )

I am less than wowed by the Shadow/Highlight adjustment. Used subtly with low amounts, it can be OK.

But used strongly, it has a tendency to make pics look quite hideous and unphotographic, garish in color, and majorly reveal shadow noise.

It's still not a good substitute for a proper exposure or a good dodging job, but it does have its uses.

Now, back to the point. Based on the majority of SC who responded that shadow/highlight was legal in basic, I plan to submit a Wacky Food image that uses that technique.

My next question is: Should I also post an admin note saying that I used Sahdow/Highlight? I assume it won't be reviewed fully by the SC unless I do - or else someone requests a DQ, or heaven forbid, it finishes very high.


UPDATE: I did submit the image along with a admin request. It has since been validated. Which means for this one case the highlight/shadow was deemed acceptable.

Well I have searched for messages that dealt with the Photoshop CS Shadow/Highlights Basic Editing matter. During many months (***) nowhere it is said by the SC that it would be illegal to use and as said by Photom a photo that used it was validated by the SC.

My guess is that this concludes that it is OK to use this tool in Basic Editing challenges and that therefore tools in other programs that do the same are ok to use too. I specifically refer to Nikon Capture 4's 'Digital DEE*' and Sigma Photo Pro with its shadows, highlights exposure adjustments and X3 Fill Light (both are RAW converters).

Is that right? I am going to use it in the next Basic Challenge.

*Digital DEE (Dynamic Exposure Extender) reveals details in shadows and highlights, correcting for underexposure in back-lit subjects or shaded areas of images and for overexposure in brightly lit areas.

You can replicate the shadows/highlight funtionality in Adobe Camera Raw during the conversion process...Anything you do to a RAW file to covert it is legal in Basic or Advanced editing IMHO.

I didn't quite understand this disussion. Is it allowed to use that shadow / highlights in basic editing or is it not?

Google Picasa is free. It has a fill light and highlight and shadow feature that provide different controls over the histogram. Highlight expands the histogram toward the right side. Shadow moves the histogram to the left. Fill spreads the histogram on the left and packs it on the right. Using fill and highlight, it is possible to get the dog's face nearly as bright as photoshop CS, but it is not possible to retain the dark tones in the grass.

Yes, it is legal as long as you apply it to the whole image, not to a selection.

What is with the halo around the dog after applying Photoshop CS highlight and shadow. Was there other editing done as well, such as sharpening?

I really like the overall appearance, which I have not been able to duplicate fully using curves or blending modes. The dog is much more true to color as is the grass than anything I have been able to achieve. Fortunately, my wife is a teacher, so if worse comes to worse, and I am unable to find my CD cover for my PS elements, it is not going to cost more than $300.

However, I would not be happy to spend that much and end up with large halos.

I just did a google search for the menu options for shadow and highlight in Adobe Photoshop CS. One of the parameters is a radius for applying the effect. This indicates a possible reason for the halo around the dog, and also argues against this being a valid basic editing technique.

I had wanted to buy Photoshop CS just for this one capability, that I did not believe I could match with my existing software.

Now, it appears that I can match it with my existing software by creating appropriate blurred brightness based masks and using different curves on each of several masked levels.

But, if I am going to end up with haloes, do I really want the shadow highlight feature at all?

I can bring out the detail in shadows and highlights by using curves, especially on the raw. I can also do it by selecting more than one "exposure" image (again especially from the raw) and screen/multiply blend the multiple images (against the basic rules for some unknown to me reason.) Each of these methods avoids creating haloes.

By the way, Photoshop CS does the shadow highlight operation at 16 bits if you wish. So for the dog picture, was this operation run on the raw or the jpeg? If it was on the raw, we have very little chance of duplicating the result starting with a jpeg.

I can do curves on the raw with Phase One C1 LE, but I like the control over drawing curves far better in JASC Paint Shop Pro, so if version 9 permits drawing curves on the raw, I think I will purchase it to resolve my shadow highlight envy.

Just a point of information which can save you a lot of money. If this is your only use of PS CS you might consider buying PS Elements, which also has shadow highlight. But if you plan on using other advanced features of CS, than Elements will let you down (no curves, limited operations on 16 bit images, no lab mode, etc.)

An article in Photoshop User Magazine on the shadows and highlight adjustment, said it was best to bring up the radius on the default settings, it tends to oversharpen when you accept the radius they choose. It is a great adjustment when you have a picture you don't think can be saved because it is too dark. The sliders give you a great control over the end results.

I find S/H very useful at times. As mentioned in the thread, it should be used in small doses. I haven't been able to duplicate S/H effect with curves. I have used it in basic editing. I seem to remember opinions a long time ago, in a thread far away, that it is legal.

Thanks nshapiro and SamT.

I think the point about 16 bit processing on all actions is an important point. Also, I use curves and lab colors on almost every picture. It looks like Adobe is going to get my money.

Now, I am wondering about plugins that I use, such as Neat Image and Focus Magic. Do they do 8 bit or 16 bit processing? Fortunately by the time I have gotten to the point in my processing where I use these filters, I have pretty well established the most significant 8 bits for each color for each pixel that will be in my final jpeg.
