In the pursuit of checking for front / back focus issues, there are several tools that are at our disposal in helping certain if there is a problem with our equipment.
For users of middle to high end Canon & Nikon DSLR models (refer to the list on our website – Canon and Nikon pages) there is the capability of reviewing the chosen / selected focus point on playback either in the camera or using the appropriate Canon / Nikon software which is supplied in the box.
Did you know however that this facility is also available as a free plug in for Lightroom users. This plug is easy to use and install and actually provides detailed information which far exceeds that offered by the Canon & Nikon software products which all in all helps with ascertaining if there is a potential problem with front / back focus issues.
The link for the software can be found below along with a description of how the plug in works.
