Saturate using Dodge and Burn Blend Modes 2 This is a simplified version of an earlier dodge and burn macro of mine in that it does not create another pixel file which wastes space. It also uses curves instead of HSL layers. Dodge and burn blend modes are one of the 8 blend modes that you change the amount of color through the FILL opacity and not the general opacity. I just modify the value of the FILL slider in curves since general opacity does not really work for this blend mode. When you leave the FILL at 100% then the effect uses only 8 colours. As you reduce the slider you add more and more colours and you also restrict the effect to the midtones and shadows, as you decrease the slider to about 15% you are then affecting only the shadows. The dodge blend mode works the same way. The difference from the burn blend mode is as you reduce the FILL slider on an adjustment layer you restrict the effect to more and more of the brights, So with the FILL slider set to 15% you are targeting the brights. Because burn really extra darkens the shadows, blend ranges are used in the curves layer to lift the shadows a little. You can set this to what is comfortable to you. The same is true for color dodge blend mode. Blend ranges are used to reduce the brightest brights that color dodge over exaggerates. Again, you can modify these blend ranges to taste.

you are right here is the correct macro. orton effect 3.afmacro

Orton Effect Make sure in the assistant is set as: adding filter layer to selection as a new layer (not a child layer) This macro adds a brightness contrast layer and sets the blend mode to screen. Then it adds a gaussian blur layer and sets the blend mode to multiply. You have the option to set the blur radius to your desired value. It also changes the blend ranges for both source layer and underlying layer in the dark areas by setting them lower as the shadows almost turn black. You can change the settings of these to suit once the macro has run. The macro also adds a mask layer to the gaussian blur filter layer. If you wish to take away the blur from certain areas ( I only apply the effect to specific areas) take a black brush, select the mask and paint out the effect where you don’t want it applied. Set the brush to 100% opacity and fill and hardness to 50%. You can then also go back and change the brightness and contrast to suit at this time. You should do that step last. orton effect.afmacro

horiz. curve to lighten/darken use picker on curve This macro sets up a horizontal curve with blend mode set to soft light. The horizontal curve cannot see 50% gray when set to soft light which is what a horizontal curve gives. Then the macro sets an HSL adjustment and sets the saturation to zero. This adjustment is then set as a child layer of the curves adjustment. When this happens, then you can see the original picture again. The macro selects the curves adjustment. The user then uses the picker in the curves adjustment and selects areas in the picture to darken or lighten directly in the curves adjustment layer. hrizontal curve.afmacro

I have created another macro that allows you to check saturation and if oversaturated it allows the user to correct it. Check and fix oversaturation with inverted layer This macro checks the saturation of an image and allows corrections using and HSL layer embedded in the macro. The macro duplicates the pixel layer and inverts it and sets the blend mode to color. This allows the luminosity to stay the same but the inverted layer inverts the colors. Then the opacity is set to 50%. Any colors that remain are shown and the saturation of the color indicates the amount of oversaturation that the inverted color pixel layer could not cancel out. An HSL layer is then inserted between the original pixel layer and the inverted layer. The user can then adjust the oversaturated color by decreasing the saturation until only gray remains. This action eliminates the oversaturation. The user then turns the inverted layer off which results in a properly saturated photo. The macro is below it is a single macro so you have to u[pload from the macro panel not the library panel. check and correct oversaturation.afmacro

When I run a macro that requires user inputs , AP sometimes allows time for the user inputs the first time or two but then bypasses the user input step. This causes the macros I have that require user inputs to fail. What is interesting it works the first times then fails. Can you look into this please . IT almost looks like a memory leak issue but I may be wrong. Thanks.

you say it does not work in LAB and should use RGB. i use LAB because of its significant advantages over RGB. saturation control works just fine when using levels in LAB. Why is it not possible to make it work in channel mixer the way it should work? Since channel mixer is offered in LAB color space please make it work as it should work or disable it. what needs to happen is that you need different controls to make it work correctly in LAB mode....further, the user guide is vacuous wrt LAB mode. thanks

i agree. first the channel mixer user guide descriptIon for LAB should be corrected. second gabrielm said that in A opponent the slider goes from green to red. actually it goes from green to magenta. further when you move the slider you adjust green but not magenta. The levels adjustment works correctly. when you selec Ao and adjust the darks in levels you adjust green, when you adjust the lights you adjust magenta. It works the same for Bomcorrectly. This is as it should be. this is not the case with the channel mixer. the sliders in channel mixer are set up for single color i believe, but in LAB you adjust two colors ( green and magenta with Ao and blue and yellow with Bo.

Just to clarify, I saw this issue with levels also in 1.6 version. Sometimes the histogram would show up and sometimes it would not. Thanks

even when using offsets i feel it's broken. And the user guide is vacuous wrt LAB. For instance in AO pull down when you modify the lightness slider you are changing magenta. when you modify the BO slider you are again modifying magenta... This should not happen. I hope Serif can fix this like it works in photoshop. I use LAB color mode almost exclusively due its strong benefits.

its still broken in LAB. even with a flattened image.

Ich auch habe die 1.7.1 und 1.7.2beta runtergelassen. 1.71 hatte Probleme mit LAB in selective color adjustment, wurde aber korrigiert in 1.7.2 beta. 1.7.2 hat immer noch Probleme mit channel mixer in LAB.

I may be missing something but when I select 32 bit output format in the develop assistant in the develop module, the output (color profile) slider selects sRGB IEC61966-2.1 (linear) which I think is the 8 bit version. I checked this in Wikipedia. However when I develop the photo and goes to the Photo persona it is in 32 bit mode. So O fee; the the slider in the develop persona is not correct when it selects sRGB IEC61966-2.1 (linear). There are a variety of color formats that can be selected in that slider but the RGB32 format cannot be selected. This is the video format that the photo persona seems to go to. I believe the slider in the develop module should reflect what was selected in the develop assistant Thank You

I believe the channel mixer in LAB color space may still be broken and the user guide for channel mixer only talks about RGB mode Here is what it says: The following settings can be adjusted: Output Channel: Select a colour mode from the first pop-up menu. Specify a single colour channel to apply the adjustment to, including the layer's alpha channel. Select from the second pop-up menu. The sliders control the contribution of the named colour to the selected output channel. Drag the slider to the left to decrease the level of the named colour, drag the slider to the right to increase it. When in LAB and say you select AOpponent from the drop down then when you reduce the AO slider to ninety percent you have taken out most of the magenta and the green remains. Once you go past zero to the negatives nothing more happens. When you move the AO slider to greater than 100% you increase the magenta. So even though the slider allows you can go below zero to negatives, nothing really happens. Now when you move AO to 50%. IN any case when you move BO to 50% with the AO selected in the drop down, you basically get close to the original because you are adding yellow but you cannot add blue. When selecting BO and making the same adjustments it acts similarly although for different colors. In any case the user guid is wrong for LAB and I feel there is an issue with the way the sliders are set up for LAB which acts differently than RGB. AM I MISSING SOMEHTING?? THANKS

Actually I am agreeing with you in my statement above I got the blue image as well when I set Ao and Bo both to zero... Even when fixed, the channel mixer will work differently in LAB than in RGB. The Ao and Bo sliders don't really work right now and I dont know what algorithm was used. I would not even speculate...

My experience is as follows in LAB. When you reduce say Ao to 50% then what happens is that only the magenta is reduced to 50% but not the green it stays at 100%. When you reduce the Bo ( after resetting the Ao to 100%) what happens is only the yellow gets reduced to 50%, the blue does not get reduced. I believe that is what IPv6 may mean. BUT in LAB the AO and Bo sliders each work on two colors which is not the case in RGB . However, if in Ao you reduce both Ao and Bo to 50% then the colors are true. Same is true in Bo . Is this the way it should be? Thanks

I also found the shadows slider in tone mappings does absolutely nothing on a variety of photos. The highlights adjustment there is extremely sensitive. in the photo person the highlights. shadows adjustment should NEVER be used. The live filter version gives strange results win RGB when you apply stronger versions of the filter. by changing the contrast All this is suggesting that the algorithm may need to be reworked. thanks

I think it would be a very good idea if Serif would let users know that the shadows highlights adjustment should not be used as Andy states above. Would save some users frustration. thanks.

I have the old NIK collection, I had paid Google for it before it went free at Google. I t works just fine as long as you follow the instructions given in earlier Affinity tutorials. I use it all the time.

Please look also at my input given here. I have not received any response about this but it is a real problem for me. Selective color adjustment does not work win LAB color space Please see and give me some input sas to when this will be fixed. Thanks a lot here is my input:

its even worse when you use LAB color space.

The LAB selective color problem defined above still exists in release 1.7.1 Please advise

Is did a little more research. This seems to happen to saturated blue only in LAB where it changes a saturated blue to magenta without making any changes ie happens as soon as you call up the selective color adjustment . The first picture is before selecting selective color adjustment, second is after selecting selective color adjustment without making any changes in the sliders. In the first picture I saturated the blue fully first. The previous picture I submitted had a lot of saturated blue in it.

selective color adjustment has this problem in LAB where it changes a saturated blue to magenta without making any changes ie happens as soon as you call up the selective color adjustment first picture is before selecting selective color adjustment second is after selecting selective color adjustment without making any changes in the sliders.

I have found a possible issue using the selective colder adjustment when using the LAB color space. I work in the LAB color space primarily because of the ability to separate color from lightness. I had no problem with this in Affinity Photo 1.6.7 Notice that blue has changed to magenta. I have tried this in RGB and found that this problem does not exist there. The first picture is the original TIFF file loaded from either Capture 1 pro 12 or Lightroom. The second picture is the same picture after the selective color adjustment is applied in Affinity photo. Notice no changes of any kind have been made from within the selective color adjustment. THis is how it comes up when you select the adjustment. If you select darken color blend mode then the effect goes away but does darken the colors. I dont believe this should happen. Thanks
