Photoshop's Gritty HDR Photo Effects

by Guest Writer

Give your photos a grunge look with this popular Photoshop effect. Although this Photoshop effect is commonly referred as HDR photo effect, it is it can be done with regular, non-HDR photos.

Give your photos a grunge look Note: This photo effect is titled Gritty HDR due to the common use of the name and is not intended to be an accurate description of the effect. HDR means high dynamic range but this photo effect does not require the use of HDR (High Dynamic Range) photos. This effect is better described as a grungy tone mapping effect that can be done without the use of HDR images.

Start by opening an image into Photoshop ... run Photoshop and choose File > Open. Browse and select the photo you would like to edit then click OK.

Photoshop CS2 or Older:
      Select the layer and press Ctrl+J or go to Layer > Duplicate Layer to create a duplicate of the layer.
Do not do any editing on the Background layer. Instead, work on the Background copy layer. This will ensure you always have a copy of the original unedited image in case you require it for further post processing.

press Ctrl+J Photoshop CS3
      If you are using Adobe Photoshop CS3, right mouse click on the layer an select "Convert to Smart Object". This will allow you to apply Smart Filters which can be edited at anytime and will keep the file size smaller.

Step 2: Make details more visible with the Shadow/Highlights tool

First, we'll mimic the tone mapping effect by using the Shadow/Highlights tool.
Choose Image > Adjustments > Shadow/Highlights.
In the Shadow/Highlights tool, adjust the settings so that all details are easy to see without making the photo look fake.

Step 3: Add a halo effect with the Unsharp Mask filter

Unsharp Mask filter Choose Filter > Sharpen > Unsharp Mask.

We will not be using this filter to sharpen the image.
Instead, we'll use this filter to add a high-contrast halo effect to the image. In the Unsharp Mask filter, set the Radius to 250 pixels and adjust the amount to get an effect that you desire.

Step 4: Add a Black and White adjustment layer

Photoshop CS2 or Older: Select
Layer > New Adjustment Layer > Hue/Saturation.
Set the Saturation to -100 and click OK.

Photoshop CS3 Select
Layer > New Adjustment Layer > Black and White.

A window with the settings will appear.

For now, just click OK without touching any of the settings and change the blending mode of the Black and White adjustment layer to Overlay.

Step 5: Black and White adjustment

Image New Adjustment Layer For Photoshop CS3 only - Adjust the Black and White adjustment layer settings

Photoshop CS2 or Older: Skip this step

In the previous step, we skipped the settings to change the layer blending mode.

Now, we'll go back and edit the settings that we previously skipped. The reason for this is so that we can see the live preview effect of the Black and White adjustment layer with Overlay blending mode instead of the Normal blending mode.

Double-click on the Black and White adjustment layer and a Black and White window will appear. In this window, adjust the settings to get the results you desire.
