My normal photo processing approach simply crops the image, tweaks the contrast and colour balance and applies a touch of image sensitive (or “smart”) sharpening. I tend to eschew more overt adjustments. However, working on this picture from a recent trip to Wales I found myself with a desire to break out the lens flare tool to complete it.
It took a bit of looking as it could be a decade or more since I last used that particular toy from the Gimp’s crowded box. You can compare it with the processed version sans flare. I think that, in this case, it does add to the image. One thing I am sure of though; I would rather be adding an artificial flare to a photo than trying to edit a real one out!
