subtle, smooth burn and dodge on skin

[singlo]

Hi, I am new here. I need some expert advice here.
I am a photographer learning to do beauty retouching. Currently I don't use dodge and burn tools for colour portraits in PS. Instead I create a new layer with overlay blendling mode and with the 50% neutral Grey check box. I paint across the model face with a soft paint brush (also airbush) tool with black (D)or white(X). Now I find it difficult to get a very smooth, gradual transition in skin tone across large areas being lightened or darkened. I try this technique with both graphic tablet and mouse pad. The only control of I have is to lower the opacity of the duplicated layer if the transition between burn (or dodge ) and untouched areas look too artificial or too "blotchy or patchy ".

I have also tried blending mode to Colur Burn or Colour Dodge using Dodge and Burn tools..but I am not happy with the subtlety of the results. Please advice.

Hello there,

have you tried using very low settings (approx. 15% each) on the Opacity and Flow settings of your brush? You'll need more strokes but you get finer control.

When I use a 50% grey overlay for dodging and burning, I usually start with a large very soft brush and an opacity of approx 4-5%, brush opacity that is, not layer opacity

Hello

The link above is a great thread that includes the technique you are talking about. Have a read through. I have only been using this method and it is much better than using blur.

Hi singlo,

Welcome to RP!

Like you I rarely use 'Dodge' and 'Burn' Tools but rather go for Overlay, Soft Light, Lighten or Darken Layers .... The only difference is that I don't even fill the Layers with 50% grey, but leave them 'blank' and simply paint on them with very soft and very low Opacity (5-10%) black, white, or 'sampled colour' brushes... (I described this technique in this tutorial.. If the result is still not satisfying or the transition isn't as smooth as you'd like it to be, ... try to blur your Overlay (etc.) Layer and just play with the layer's opacity ....

Hope this helps ....

The best method to total control is heyrad technique. I am with you shellby.

Thank you all of you for the quick responses. I am so pleased to find this forum by accident .

Now i know the problems were..i was using 30% brush opacity and 50% flow rate which were too high . I have just tried 5%-10% brush opacity, it is good for subtle work. 15% flow rate and opacity are also good for larger areas. Thanks for the tips. now .

I will print out Heyrad technique..at the moment his technique seems a bit overwhelmingly complicated for me to digest...

Flora, thanks for the tips about blurring the Overlay layer.. I will check out your tutorial learning how to sample colour with brushes.
Thanks again.

After studying Heyrad's post several times, I have managed to get his "lighten-darken-desat-contrast" curves layer set working now. I am still struggling a bit to master his technique...this is something really advanced for me . Thanks.

Don't worry just keep at it. It will come. I only use that method now. Also I find that you can use the 50% gray softlight layer and use white or black to dodge and burn - opacity of the brush can be from 2% to 10%

I have also used the curves method, but I ended up going back to the softlight method. Same thing really but my mac seemed to handle the gray softlight one better. The other one made my mac lag and I couldn't see the result right away - I had to wait a bit to see the difference and this was annoying. I have almost a gig of ram, but perhaps I should get more!

Good luck.

I just started an intensive program with my friend who is a professional photographer to enhance my photoshop skills. I have not tried the method discussed above, so I cannot comment about it.

I was told to stay away from the automatic dodge and buring tools.

I have had some good results using quick mask on the main focus of the photo and inverting it. I then adjusted the background with a filter blur of 250 and histogram adjustments.

I just started doing this within the past two weeks, so my comments are very limited. My friend said that he has not had a need for using curves. I guess that PS has many ways of accomplishing things. I'll comment more in the future when I have developed more experience.

Greetings singlo,

This is a favorite technique of ours and it's understandable WHY you can't get nice transitions using a soft Brush on the gray layer. The Brush is just too brutal even at lower opacities. Instead, use the Dodge/Burn Tool on this layer (set to a low Opacity). Yeah! It sounds weird (we know) especially since you are trying to avoid using these tools directly on the image. But the truth is, they work remarkably better than anything else! And it still works non-destructively by being on a separate layer.

Using the Dodge/Burn Tool works similar to using the Brush Tool but instead of pressing the x key to move back and forth between black & white, you set the tool to Burn and hold the opt/alt key to toggle using the Dodge tool.

The reason these work better in this situation is because of how they only affect the (gray) layer's luminosity and not adding pixels (like the Brush Tool). The result is nice even transitions in your lights & darks. You can also try Flora's suggestion of using the Blur Tool (press r) to smooth out transitions further (if needed).

A technique we use is one called "mottling." This is a method used by classical artist, whereby the larger patches (or blotches) of light & dark are applied roughly first then smoothed out (almost completely obliterated) then another layer is built upon this and smoothed out again. This is repeated several times and give the image great depth and dimension as well as a natural complexity. With paint this was literally "building-up" the transparent glazed paint layers.

With Photoshop and this Dodge/Burn technique, you can do something similar by adding larger areas of light & dark then using the Gaussian Blur to soften them way down. Then again, add more and blur again until you have the look you want.

We prefer using Overlay with this technique but certainly Soft Light can be used as well (with much softer results).

This technique is also a great way to create an artificial "Fill-flash" for those images that are well exposed for the background but under-exposed in the foreground. Just use the Dodge Tool on the gray layer to lighten up the image where it needs it the most.

thank you so much for the tips. Klaatu, I have just tried your technique, it work well too--the only thing slows me down is that i have to keep reminding myself to switch constantly between hightlights, midtones and shadows option on the Dodge& Burn tool menu during the process. It is easy to forget when I work on a portrait with rich variations of tonal range.

I have also tried out lighten mode with brush tool colour sampling for dodge, and Darken mode for burn which is very much like Flora's method.

Shellby, I think too the curve method does the same thing too, except it also allows you to see the dark or light spots more clearly from the destaurated, high contrast image. I guess Heyrad's technique combines burn/dodge and spots removal in one process, if I understand it correctly. I prefer to use more simple method. At the moment I do skin smoothing separately using clone stamp at 25% opacity on a new layer on 50% opacity, viewing the Green channel(GlitterGuru's method). Before I learnt retouching, I used lazy person's quick fixes like Kodak GEM Airbush plug-in at medium setting and Neatimage, which both give plastic look at high settings, smearing out skin texture. I guess I can combine one of these plug-in filter tools at low settings with manual retouching.

You're welcome!
Yeah, it does take a little experience with it to get used to, but the easy part is that in the interim you can either backup a step (or two) in history (press cmd/cntrl+shift+z) or just go over the mistake with the opposite tool. The really great part about using this method is that it isn't obliterating the gray pixels, it's just shifting their luminosity lighter or darker. So, you can easily use the Burn to darken the (accidental) highlights and the Dodge to lighten the (accidental) shadows. No harm, no foul.

Another thing that helps is that setting the foreground color to gray and then just pressing "b" for the Brush Tool will erase anything that you've done (be sure to switch back by pressing "o").

An alternative method (that is similar to heyrad's) would be to make two layers; one for Dodge and the other for Burn. The purests will love this since it keeps the two effects (highlights & shadows) separate and allows opacity (or mode blending) to be separate as well. This way you can also focus on one tool at a time without having to switch. However, this maybe overkill with most images that just need a little touch-up.

We've made the creation of the Dodge/Burn Layer(s) an Action which cuts down even more time. The Action also selects a preset of the Dodge/Burn Tool so, just one click and we're ready to roll. We're very used to the convenience of just using the opt/alt keypress to switch back and forth as it gives a greater sense of painting on the image (especially with a tablet).

Oh, that reminds us, you can also set the down-button on a pen to be the opt/alt key, this way you don't even have use the keyboard. Although, we've set ours to be the Zoom Tool (up and down) which is nice to get into those small details. But this would all be in the realm of personal preferences.

thanks again Klaatu, good idea. I have made actions for each of these methods.

The reason these work better in this situation is because of how they only affect the (gray) layer's luminosity and not adding pixels (like the Brush Tool).

I am not entirely sure if Brush Tool on Overlay Mode can cause colour shift of the pixels (I thought I read from somewhere that it doesn't), but I do notice unnatural shift in lighter colours, particularly burning the lighter colour tone with the Bush tool in special situations, e.g. when I try to transform a normally lit portrait to a low-key image with lots of post-production add-on shadows. The white dress of the model would turn to yellowish brown if darken it with Brush. So Burn/Dodge tool layer maybe the answer to this problem.

Re color shift with 50% gray layer in Overlay blending mode.

Try Softlight instead of overlay. It seems to minimize the color shift.
