How-To Tips: Preparing Photos For Large Format – Using Lens Correction

This article will discuss why we recommend Lens Correction as your first step in image editing, and explain how to do it.

Chromatic Aberration, also known as “colour fringing” or “purple fringing” is one of the most common problems we see when we are printing large format photo prints or printing photos on canvas for photographers at ABC Fine ART. Sometimes it happens even with very experienced photographers who have been printing large format photo prints for a long time. Most of the time it’s an oversight issue.

This issue happens when the lens fails to focus all colours to the same convergence point. As a result, the image can look blurred or have noticeable coloured edges (red, green, blue, yellow, purple, magenta) can appear around objects, especially in high-contrast situations. It is more noticeable on large format photo print.

There is a very simple software filter solution for chromatic aberration, especially when you are working with an image in RAW format. Make sure you check your picture in 100% visibility, especially on corners. If you see this problem just use a Lens Correction filter as your first step in image editing.

Make a Smart Object Before Editing your Raw Image

Sometimes the following lens correction method won’t work in Photoshop if you already have done editing on your image (e.g. cropping) and saved it. Making  a “Smart Object” of your RAW image in Photoshop is very useful because you can always go back and use this method later.
