X-ray photography can be much more than a security measure or a way for doctors and dentists to see inside us. Some photographers and radiographers have used the equipment and film to make X-rays to create striking and vibrant studies of flowers and other similar subjects.
While the results can be spectacular, most of us don’t have an X-ray machine tucked away in the back of the cupboard, so in this walkthrough we’re going to take a look at replicating the X-ray effect. The characteristic negative tones and cyan hues that are typical of many X-rays are a wonderful way to give your images a creative twist.
We've used Photoshop to convert our image to black and white, invert the tones, and then add a colored tint and a subtle glow. Using a non-destructive and re-editable workflow with Adjustment Layers and Smart Objects, you’ll also master some essential Photoshop skills that’ll come in useful for other projects.
Let’s see how it’s done!
01: Shoot a suitable subject
Shoot it Lots of objects work well with this technique, from kitchen utensils and plastic toys – to the old Nikon F3 film camera we’ve used here. Photograph your object on a white background – it will end up being black once the image is inverted.
For an X-ray-style glow, the lighting from a ringflash is perfect, so if you’ve got one, attach it to your lens and use it. If you’d prefer a white background in your finished images, shoot your subject on a piece of black card or cloth.
02: Process in Raw
Download the image and open it in Adobe Camera Raw, or use the file ‘xray_before.NEF’. Go to the HSL/Grayscale tab and check the Convert to Grayscale box. Return to the Basic panel and set the Highlights slider to -99, the Shadows slider to 75 and Clarity to about 50 to eke out as much detail as possible.
03: Invert the tones
Duplicate the background layer and go to Image > Adjustments > Invert, or hit Ctrl/Cmd+I to do this. At this point, it’s a good idea to select the Dodge and Burn tools from the Tools palette to selectively darken and lighten parts of the image, making sure there are no deep shadow or glowing highlight areas.
04: Add a color tint
Add a color tint Go to Layer > New Fill Layer > Solid Color, and from the color picker, choose a bluish X-ray tint – R41 G51 B120 is a good starting point. At the top of the Layers panel, select Hard Light from the Blend Mode drop-down menu. It’s worth experimenting with some of the other Blend Modes to see which effect you like best.’
05: Tweak the tones
To alter the tones, create a Curves Adjustment Layer and bend the upper half of the curve upwards to make the light tones a little lighter. Place an anchor half way down so the dark tones remain unaffected. Now use a Vibrance Adjustment Layer to tweak the intensity of the colors. Here we’ve reduced it a little.
06: Add final glow
A final glow Hit Shift+Alt+Ctrl/Cmd+E to merge all of the separate layers into a new layer at the top of the layer stack. Convert the layer into a Smart Object and go to Filter > Blur > Gaussian Blur and enter a blur of 70 pixels. To finish off, change the Layer Blend Mode to Soft Light and set the Layer Opacity to 25%, or to a value that suits your subject.
