Note that I added a gradient blend on the floor area so that the ground level closest to the model would evenly stay sharp. How much effort you put into fixing the depth map mask again depends on you and what kind of image you’re using. Use the number keys to quickly change the flow of an airbrush or opacity of a paintbrush. Use the X key to switch between black and white paint colors as you modify the mask. Use the bracket keys to change the brush’s diameter as you go. It’s difficult to tell you exactly what to do here since there are so many options.įor this image, I mainly used the pressure-sensitive pen method. You can use a pressure sensitive pen to simply paint away the ugly areas, or you can use some of the color channels from the original image to create selections or sub-masks and use those to paint away the ugly areas… the possibilities are endless. There are tons of different techniques you could use here as well. Basically, you need to use painting tools with varying levels of black, white, and grey to edit the layer mask until it looks right. This is where you need a bit of skill and you’ll probably need to change your technique depending on what kind of image you’re working with. So next you’ll want to get your painting tools ready because we’re going to fix that depth map manually. It’s a terrible mess!! Now you can control itĪll of that work to get something that looks just as bad as what the camera phone did automatically may seem like a wast of time, but NOW we have that Photoshop file set up so that we can actually control things with a lot more flexibility. Now I’m going to apply a Gaussian Blur filter to the bottom image layer and we’ve got almost the same thing that the phone’s background blur filter would have done. ![]() You can see this causes a lot of banding between the depth levels because our depth map does not have much range or resolution. So I’m going to hit Ctrl + M and use the white eye dropper to click on her forehead in order to make the model’s mask area white and therefore opaque. Now, you’ll notice that my model’s face is 87% black in this depth map. I’m going to use this to make my subject remain sharp and unmodified while letting the far away areas be blurred by a filter. The white areas are the things closest to the camera while the black areas are the furthest away. This will let you see the greyscale levels of the layer mask. Next, Alt/Opt click on the layer mask that we just created in the Layers palette. This top layer will be our in-focus layer. Then select the image layer copy and choose Layer > Layer Mask > Reveal selection to create a layer mask. Next I’m going to make a copy of the image layer by dragging it to the new layer icon in the Layers palette, then I’ll load that Alpha channel as a selection by Ctrl + clicking on it. ![]() Then we should probably do File > Save As > and make a new PSD file to preserve everything. Next I’m going to create a new Alpha channel in that DNG file and Copy/Paste the image_depth.jpg into that Alpha channel. ![]()
