In this tutorial, I will be showing an easy and effective way to simulate an infrared look from just an ordinary photo, no expensive infrared cameras required. Infrared photography creates a bright white effect on green foliage, adds glow to objects and can alter colours drastically. There are many ways to recreate this look so feel free to add your own spin on this basic technique.
Step 1: Materials and Camera Settings
MaterialsCamera (I used this point and shoot camera, but of course if you have a DSLR available that would be even better) Photoshop (I used CS6 but I believe CS5 will work as well)Tripod (optional)
Just to briefly explain how I took my pictures, I had my camera on program mode. As I was shooting outside on a bright winter day, I had my white balance set appropriately. The exposure I adjusted shot to shot depending on which direction I was facing, but for the most part it was set a bit below zero, one or two units to the left. This technique works best on scenes with a lot of colour and texture, which is why greenery works very well, and lots of sky and water.
Step 2: Open Image
Select the image you want to convert to infrared and open in photoshop. Duplicate the original layer either by right clicking on it and selecting 'Duplicate Layer' or by pressing 'Ctrl/Cmd' and 'J'. You always want to keep the original layer so you can fall back on it and compare it to the editing you do.
Step 3: Adding Contrast with Curves
Go to Layer > New Adjustment Layer > Curves. In the dialog box we can add contrast to the image by moving the line on the graph up near the white end (right) and down towards the black end (left), creating an 'S' curve. Adjust this to your liking.
Step 4: Curves Con't
Select the Curves Layer and the Duplicate Background Layer, right click and select Merge Layers. This will combine them into one layer now called Curves.Your new layer should be more vivid and have more contrast.
Step 5: Convert to Black and White
Go to Layer > New Adjustment Layer > Black & White or go to the New Adjustment Layer Symbol at the bottom of the Layers palette and select the same thing. This will convert the photo to black and white instantly.
Don't close the dialog box just yet!
Step 6: Convert to Infrared
In the Black and White Dialog box, select the preset Infrared.
Step 7: Adjusting the Colour Channels
In the same dialog box, you can adjust the different colour channels. This will brighten or darken parts of the photo. You don't have to have the exact same numbers, just adjust until you're happy with the look of the photo you've chosen.
Tip: If you ever need to open the dialog box again to readjust, simply right click on the adjustment layer and select Edit Adjustment.
Step 8: Lower the Opacity
Go to the Opacity meter in the Layer Palette and decrease the opacity. I lowered mine to 70% but you can change it until you're happy with it. Doing this allows the colour of the layer beneath it to peek through.
Step 9: What We've Just Done
This is a comparison of the changes we've just made.

Top Right: Changing Preset to Infrared

Bottom Right: Lowering Opacity
Step 10: Altering the Hue/Saturation
Go to Layer > New Adjustment Layer > Hue/Saturation. Alter the Hue and Saturation until you're happy with your image. For this I looked up 'infrared photography' for inspiration and I liked the pink foliage look so I adjusted mine to be soft pink.
Step 11: Comparison
This is before and after altering the hue and saturation.
Step 12: Flatten Image
You can do this one of two ways:Go to Layer > Flatten Image. This will condense all of your layers into a single locked layer.Select/highlight all of your layers (there should be four), right click and select Merge Layers. This will condense your layers into a single unlocked layer.
If you don't want to lose your process layers, simply duplicate your layers into a new psd document and flatten them in the new document. This is what I did.
Step 13: Duplicate the Flattened Image
In your new document or after merging your layers into one, duplicate the new single image. This will be our finishing touches layer.
Step 14: Transform
Press Ctrl/Cmd T to free transform or go to Edit > Free Transform. This will select the whole picture. Make sure you either press the link button between Height and Width or hold shift while you drag to keep the aspect ratio the same and not stretch the picture.
Step 15: Transform Con't
Transform the layer just a little bit larger than the original, and then center the transform box over the canvas.Click enter or the checkmark at the top to confirm the transformation.
Step 16: Screen
Go to the Blending Mode drop down menu beside the opacity meter in the layer palette and select Screen
Your picture should now look like this.
Step 17: Add Noise
Go to Filter > Noise > Add Noise. In the dialog box ensure that Gaussian and Monochromatic are checked.Add as much noise as you'd like to the photo. We will be reducing the opacity of this layer, so you may want to add more than you think you need.
Step 18: Reduce Opacity
Make sure the proper layer is selected then reduce opacity to the percentage you like best. For this picture I didn't want too much, so I went to 30% but feel free to leave it more opaque.
Step 19: Adjusting Levels (Optional)
I wanted to make my photo just a little darker after I had finished those last effects so I adjusted the levels. If you want to adjust the tones of your photo again: Go to Layer > New Adjustment Layer > Levels. Move the black, grey and white sliders until you're happy with your image.
Step 20: Final Comparison
This is my final photograph. The effects on yours may be much more drastic than mine as I didn't want mine to be over the top. Other suggestions for effects that I did not include are:Adding a Gaussian Blur (found under Filter > Blur) Adding Grain (found under Filter > Texture)
