Are you ever disappointed with your photos? Do you get frustrated when you’re editing because you’ve been told to move certain sliders, but never been told WHY? Do you wish you could transform your photos without having to spend hours in front of the computer?
In my new book, Adobe Lightroom - Edit Like a Pro, you’ll learn:
how to to analyze a photo like a pro, saving you hours of frustration.
WHY you might want to move specific sliders, instead of just following recipes.
what the sliders are doing behind the scenes.
how to use sliders together, instead of in isolation, so you can get the optimal result
The book is based on the cloud-native Lightroom desktop and mobile apps, but the principles also apply to Lightroom 6 and Lightroom Classic. The sliders are arranged into slightly different panels, but there's an included PDF that shows you where to find them in Lightroom Classic/6.
The simple answer is that you use a polarizing filter on the camera lens BEFORE you take the photo. Simply stated glare is an over exposed part of the image. Once over exposed, you can not put color information back in. As digital values recorded by the sensor, White and Black are the presence and absence of all color information (all ones or all zeros). Colors are the numbers in between. If there is any color information present in the whites or darks, you can amplify that to boost the color values. Once you have achieved all ones in the binary value for the pixel there is no way to convert the binary ones to some binary value for a color.
The best that you can do in LR is to work with the pixels around the edges of the all white area to boost the color of the pixels that are near white but retain some color information. The highlights adjustment slider can help as can reducing the local exposure with the local adjustment brush.
Removing the glare in post processing can be very challenging. Your best option is to use a polarizing filter on your camera lens when taking the photo. In Lightroom, you can reduce the Highlights and Whites while decreasing the black point in certain areas with the brush tool or the radial filter, but this is the challenging part. If you have a really bright white glare on your image and you reduce the highlights, you may be able to recover some of the information, but it's more likely that your Bright White area will turn into a less bright grey area.
