HOW TO USE LINEAR DODGE (ADD) & LINEAR BURN BLEND MODES ON IMAGE

Laupahoehoe Harbor on Maui, HawaiiThis week I am presenting an oldie but a goodie that was done quite a while ago. Decided to try it out again with some new images and I still like this technique. It is just slightly different from the normal Dodge and Burn techniques and very simple to do. The above image was taken on Maui, Hawaii at the very breezy Laupahoehoe Harbor.

I learned this at a Photoshop World several years ago and am not sure who even presented it. It was just in my notes so I thought I would give it a try and got some really nice results! The workflow is pretty simple:

  1. Duplicate the image twice after doing the basic color and tone corrections to the image.
  2. Add black layer masks to each layer by holding ALT key while clicking on the Add Layer Mask icon (rectangle with circle in center) at the bottom of the Layers Panel or by pressing CTRL+I in a white layer mask.
  3. Now on the top duplicate layer, change the blend mode to Linear Burn and name it Darken.
  4. On the layer underneath, change the blend mode to Linear Dodge (Add) and name it Lighten.
  5. Using a soft round brush set the Options Bar Opacity to 9% and Flow 55%.
  6. On the Lighten layer mask paint in white over areas to brighten. Do same for Darken layer mask on areas to darken. Since the Opacity and Flow are set fairly low, it will be a build up effect to get just the amount needed.

It is a very easy way to add a little color and/or focus to different parts of your image. If the effect is too strong, just lower the layer opacity. Also, the Linear Dodge (Add) blend mode could be used as a spotlight effect to fill darker areas with some soft light. For the above, the Lighten effect used the Linear Dodge (Add) blend mode at 75% layer opacity and the Color Burn blend mode did a great job on darkening with a layer opacity set to 48% – the Linear Burn was too much for the shadows in this image.

Just to let you know what is happening with these blend modes, here are the blend mode explanations according to Lesa Snider in her Photoshop CS6 – the Missing Manual book (an excellent book BTW):

Linear Dodge (Add) – “Lightens your images by increasing its brightness. It is a combo of Screen and Color Dodge modes, so it lightens images more than any other blend mode. But since it tends to turn all light colors white, it can make an image look unnatural.”

Linear Burn – “In this mode (which is actually a combination of Multiply and Color Burn), Photoshop darkens your image by decreasing its brightness. Linear Burn produces the darkest colors of any Darken blend mode, though with a bit more contrast than the others. It has a tendency to turn dark pixels solid black, which makes it ideal for grungy, textured collages…”

From this it is apparent that Linear Dodge (Add) can make an image look unnatural so take care when using it. And Linear Burn can give a grungy effect so watch the results of this. Therefore if your image does not look quite right, try changing the layer blend modes to Screen or Color Dodge for the Lighten layer, and Multiply, Darken or Color Burn (as I did above) blend modes on the Darken layer. Experimenting with blend modes can give some great effects! Image taken on the Big Island in HawaiiThis image is from the Big Island in Hawaii after a short rainfall. Just painted areas to lighten and areas to darken using both the Linear Dodge and Linear Burn blend modes. Used Nik Viveza 2 to even out the colors.

Hope you get a chance to try this little technique – pretty easy to do and can give some great results. See ya later!…..Digital Lady Syd
