A view of The Ruined Abbey grotto at Painshill Park in Surrey, UK, shot with an 850nm IR filter. The second image had a Gaussian blur applied to it (amount 20 pixels) to give a soft halo around detail edges. The amount of blurring is highly adjustable according to taste.

Next, apply a Gaussian blur filter to the duplicate image (Filters > Blur > Gaussian blur). You can experiment with the amount – try 30 pixels radius to start with. Now, slowly reduce the opacity of the duplicate image using the opacity slider so that the original starts to show through. There will be a glow effect in the image. This technique works really well with woodland images and other landscapes. Obviously you can vary the effect greatly.

When an image is downloaded from the camera it may have a pinkish or bluish tinge depending on the filter used. There are several methods in software programs for converting a colour image to black and white. Adobe® Lightroom, for example, has a number of presets including B&W high- and low-contrast and B&W landscape. More black and white presets are available from a number of sources for further choice.

In the Adobe® Camera Raw converter, clicking the B&W button in the Treatment menu will enable monochrome only editing. In Photoshop® itself there is the option for converting colour images to black and white (Image > Adjustments > Black & White), that again, gives complete control over the tonal balance of the image.
