Math behind Photoshop linear density (add) blending mode

• Blending modes within several compositions embedded layer - please help?

  I have a main composition that contains multiple embedded compositions.  Fairly typical workflow.

  Let's say that the main composition is called 'main_comp' and one of my embedded compositions is called "comp_A".

  In comp_A, I have a solid layer of black with a lensflare effect applied.  I have this set to 'Add' blend mode layer, so that all the black pixels are ignored.  This allows all images under this lensflare layer to show through.  This set works very well in comp_A.

  I integrate comp_A into my main_comp.  The 'Add' on my lensflare layer blending mode displays more correctly once inside main_comp.  The layer makes it totally opaque block anything in the main_comp below.

  I hope that makes sense.  If someone has the time to help, I can provide more information if necessary.  Thanks in advance.

  Press the "collapse of transformations/continuously Rasterize" for comp_A in your main comp - who could do.

• Blend modes Photoshop CC 2015.5 does not

  I have a pixel layer where none of the blending modes are applied. I'm on Mac, RGB, 16-bit. I am an experienced user of Photoshop, but have never experienced this problem. I can apply adjustment layers, but some blend modes not.

  For some reason if I opened a texture & then CMD J put another layer I can blend modes to get to work.

• Layer masks and blending modes

  I read on the layer blending modes in Photoshop CS6: The Missing Manual, p.121.  They talk about setting exposure using the blending modes, and they show how to darken an image by using the following procedure.  (1) activate a layer, (2) create a mask of levels, (3) the blending mode of the layer to multiply the value.

  My impression is that blending modes change how the pixels on one level interact with the pixels on the next lower level; that is, it implies there are at least two layers of the image.  So I'm not surprised that if I have a single layer without a mask and I change the blending mode from normal to multiply, it is without effect, probably because there is no immediately lower level to allow interaction.  However, if I have a single layer and create a layer mask, then changing the blending mode from normal to multiply darken the image.  That must involve the pixels of the layer are interacting with transparent pixels on the mask.  What?

  Can someone explain what is happening in reality not here?

  Use layer blending modes, you need to the two layers less.

  As you mentioned above:

  '(1) activate a layer, (2) create a mask of levels, (3) the blending mode of the layer to multiply the value'

  step 2 means create a levels adjustment layer that comes with a default mask if you want to make local adjustments.

  in this case, if you have a layer and add an adjustment layer, it works as if you duplicate the layer.

• In EP 13 blending mode

  I have 13 items first and understand it supports (such as Photoshop Elements) blend modes... but can't find anything in the menus, etc. to help me get started. How to access this feature? I searched all the menu, drop-down menu, etc and can't find anything. I want to use "multiply" to try to darken a bright scene. Thank you.

  Add On... after having thought about trying to mode of fusion of keyframes in Premiere Elements. My first impression, don't is not possible... you could cut the video on the premises in question.

  I will think on this subject, more still, but until this no keyframing mode of fusion in Premiere Elements.

• Blend Modes ('bright light') in After Effects?

  I discovered that in After Effects CS6 (Win7) some blend modes seem to not work as expected.

  I have a bitmap with transparent above other bitmap and want to mix with "bright light" - but the result is the same, as if I had no merger mode at all. It is the same for 'hard light', 'linear light' or 'hard mix.

  Other blending modes like "multiply", "soft light" and "overlay" work very well.

  Does anyone have an idea what's wrong with my After Effects?

  If you imported the PSD file with the blending modes defined this way instead of PNG ones, AE should have created Layer Styles property group. Drilling down this ownership group reveals the property opacity of fill under Merge-> Advanced Blending Options:

  

  In order to correct your design created from PNG files, you must export the layer with 100% Fill first, and then you add any layer Style of the layer-> Layer Styles menu (or right-click-> Layer Styles) - that creates the layer Style group property of the layer. After that, you are free to manually delete or just disable the eyeball and enjoy working with the only blending Options property group.

• Hue Blend Mode Confusion

  Hello

  Read on the blend mode of hue, I understand (perhaps wrongly) that, given two layers (T) op and (B) ottom, if the Mode of T mixture has Hue, then the information of hue in T will be mixed with the saturation and brightness in B, which means that the information of hue in B are replaced by information of hue in T. However, by running a series of experiments, I have noticed that when dealing with a very simple document consisting of two layers only, that affecting the tint also blending Mode changes the saturation and brightness.

  Here are the steps to replicate the phenomena observed using two regular layers:

  1. Create a new blank document.
  2. Fill it with the color that corresponds to the values (0, 70, 50) HSB.
  3. Add a new layer above the existing (Normal blending mode).
  4. Fill the top layer with the color that corresponds to the HSB (230, 70, 50) values.
  5. Use the Panel information, TSL values for the document he read (230, 70, 50).
  6. Change the blending Mode of the top layer of the hue.
  7. Use the Info Panel, the TSL values for the document should read (230, 70, 50), but rather to read (230, 66, 53).

  And here are the steps to reproduce the observed phenomena using a normal layer and an adjustment layer:

  1. Create a new blank document.
  2. Fill it with the color that corresponds to the values (0, 70, 50) HSB.
  3. Add a Hue/Saturation (Normal blending mode) adjustment layer.
  4. Adjust the value of shade in the properties panel for the Hue/Saturation adjustment layer at-130.
  5. Use the Panel information, TSL values for the document he read (230, 70, 50).
  6. Change the blending Mode of the Hue/Saturation layer to be dyed.
  7. Use the Info Panel, the TSL values for the document should read (230, 70, 50), but rather to read (230, 66, 53).

  The results in both (for me) are identical. Am I misunderstood the blend mode of hue?

  Thank you

  The mixture goes in a model STL.

  You make measurements in a model STL.

  In addition, change the hue by preserving the brightness and saturation sometimes would result in illegal values - and those who have to be cut back to valid values (while preserving hue).  This will result in changes in brightness or saturation.

• Blending modes: PSE vs PS

  Blend modes is a topic that I know well.  I saw an interesting book on this subject, but it was written on Photo Shop.  Is there a difference in merger between PSE10 and PS modes?  TIA

  If you ever far enough into the blend modes you want to subtract and divide blending modes in photoshop elements:

  fracture:

  Invert the layer (Ctrl + I) (mac Cmd + I) or (filter > adjustments > invert) then change the blending mode of the layer to Color Dodge.

  Subtract:

  change the blending mode of the layer to linear burn and then invert the layer (Ctrl + I) (mac Cmd + I) or (filter > settings > invert)

• Shift to dissolve linear density

  When dissolved in addition 14 frames of a white work to an identical white work with a title, I make a dip in the brightness and I don't understand why. Layer modes are NORMAL. Layer 1 fades from 100% to 0%, and Layer 2 fades at the same time from 0 to 100 disappeared opacity.

  Point 50-50, the brightness of the white card plunges permanently. I'm able to offset a little by pulling on the Bezier handles in the opacity to get a logarithmic curve, but why is that need? 50 per cent more than 50% must be equal to 100 per cent. There should be no change in brightness! What I am doing wrong?

  Thank you

  Add alpha blend mode! The default AE of transparency of mixture is not linear. as a result, 50% / 50% real transparency more like 80%, not 100%.

• Blend modes

  Only normal and add are available in the display properties section. This program is ready yet? On the edge you can add the code to display layers as overlay etc, why this feature is not available in the new version to animate? Your manual is severely lacking.

  Edge manipulates the DOM objects, so it uses the CSS blend modes. Renders animated to a unique canvas element, so it uses the canvas blend modes. They are in theory good enough, but Adobe is at the mercy of browser manufacturers to really support this standard. Currently, the only "fancy" blend mode supported by all major browsers Add's the only exposes the IDE to animate.

• Keyboard shortcuts do not work after changing the blending mode to a layer

  There is a strange bug that I experienced with photoshop. Whenever I change the blending mode to a layer (for example by selecting "Multiply" in the menu drop-down blending mode), my keyboard shortcuts stop working until I have click on the canvas again. It's annoying because often, I'll be on the Brush tool and I did draw on the canvas and press ctrl + z to re - activate keyboard shortcuts. I'm curious to know if this problem occurs to someone else and if anyone has found a solution for this.

  Version of Photoshop: 20150722r.168 x 64

  Operating system: Windows 10

  It happens on Windows, because the drop-down list with blend modes remains highlighted or active (around the blue line). You can press ENTER to confirm and delete the highest point around blend mode dropdown or use keyboard shortcuts to change the layer blending mode. To change the layer blend mode, you must have selected layer and then press Shift + Alt + letter for the blend mode. This shortcut does not work in the case where the tool you are using have mode option in the blending Options bar.

• How can I get around by pressing 'enter' to select blend modes?

  [In Photoshop cc on PC] Whenever I change a blending mode layer, stays of area highlighted in blue until I press "enter". On mac (pre-creative cloud), I did not have this problem. I could simply select the blending mode of my choice and go about my business. I frequently change blending modes and having to stop, then select 'enter' each time I do it becomes a real problem. Is there a setting I can change to keep the box of your stay highlighted?

  I looked around this forum and couldn't find anyone else with this comparative issue except for someone with a similar problem in 2014 which have remained unanswered. I hope that I don't end up like this poor lost soul.

  Shift + you will allow to scroll the Blend Modes. Enter not required.

• How to change shortcuts for blend modes?

  Hello. I would like to change the default hotkeys for blending modes(brush):

  Default shortcuts in Adobe Photoshop

  but I can't find one any of them listed anywhere in the customization window shortcut. Is it possible to customize them all?
  And if so, I am able to assign a simple shortcut (F5, F6...)?

  Any help is appreciated!

  I'm sure they're hard wires, and you wouldn't be able to use the unique key without modifier anyway.  I expect that you realize that the blending mode shortcuts are context sensitive?  If you have a tool that uses brushes, blending mode shortcuts affect the blending mode of the brush.  Otherwise, they affect the layer.

  Have you considered using a keyboard or mouse game?  Logitech gaming keyboards have a number of app sensitive "G - keys" you can program with anything a shortcut to a block of text.  It is very easy to use a set of keys to release of Photoshop shortcuts with a push.  The keyboard below has 12 keys with banks of memory game three, so 36 options.  I use mine for workspaces, perform actions, turn Lee Nezumi on and off etc.   I also use it for Firefox and conclude these discussions of the forum long links with a single touch.

  

• blending mode does not work.

  I am unable to use the mix mode (screen) on my videos (shockwave) stock. He worked earlier but for some reason, he decided to stop working. He used to work with only the video layer stock alone, but now its not let me do blend with a single mode layer, now I have to use several layers for it to work. If I disable the other layer (not the stock of video) there is a black screen where the transparency is, as if it's a video of regular stock, same flood on the screen is activated. It's stupid because I just could, be able to have a layer and blend mode would continue to operate. Basically I can't use on a single layer blend modes as to make black become transparent. even if I could do a few minutes ago. Ive tried resetting preferences, Ive tried to restart the computer. With no luck. Someone help me please ():

  Here you can see that his game on the screen and the background is transparent but still black is not transparent.               Here, there is a red solid layer below the video of stock, which is on the screen. It works fine, but I don't want to have to add a solid layer, whenever I want something from the screen.

  

  You're wrong. The screen mode creates no transparency, it does that add some pixel values with a luminance value more high than black. Screen does not generate transparencies, never, never will.

  You can use Knoll Unmult to ensure transparency of the black areas in an image. It's easier work.

• How can I copy a layer but have the blend mode reset to normal?

  I'll try and this word as well as I can lol. I edited a layer with a blending mode and you want to copy the layer but have the blend mode of the layer to return to normal so that I can edit it again with a different blending mode.

  Does anyone know how can I achieve this? Any help would be appreciated!

  I don't know what you have in mind, but if I understand your goal, try this:

  On a given layer, add a blend Mode of your choice

  Then add an adjustment layer (say, curves), but do not alter the curve. Simply choose the mask and apply a different blending Mode.
