![]() ![]() The automatic tools in Lightroom and flexibility of raw films allow color changes to happen non-destructively. See how big of a difference the image format makes? Raw VS Jpeg files with ND filters Here’s what the image looks like when I try to correct the color cast from a JPEG image. Sometimes it makes the image too magenta, or too yellow in an effort to make a blue sky grey. But I always have to further adjust the white balance to get it just right. But in most cases, Lightroom does a really good job without a grey card. These simple, cheap tools do make post-processing a little easier. It’s best to choose a grey color in the mid-tones, which is one of the many reasons photographers often bring along a grey card to make sure they’re getting the most accurate colors possible. Lightroom will take a 5-pixel by 5-pixel sample of those colors and automatically change the white balance so that those pixels move as close to grey as possible. When you click this, then move your mouse onto a position that has a good amount of what should be white, or neutral (read: grey) colors. Follow the green arrow to the color picker in Lightroom. This can be found in the basic editing panel in the Develop Module just below the histogram. When I get into Lightroom, the easiest way to remove the color cast is to start by using the white balance selector. But that often results in these kinds of casts, because it’s difficult to set the balance when you’re seeing the image through a really dark screen. All the images have to have exactly the same white balance and exposure to make a panorama, so it’s a good practice. This is because I always check my settings before putting on the ND filter. ![]() It doesn’t always occur in my images, but it typically happens when I need to make panoramas. But the blue casts made by LEE Filters are some of the easiest to correct in post-processing. Every ND filter makes a color cast of one kind or another. In the image above, I used the Lee Big Stopper, which is well known for creating a deep blue cast. Luckily it’s an easy fix in Lightroom! The quickest method for removing color casts This is what happens if you white balance before placing an ND filter on your camera. But until they do, I will keep ND filters in my bag. It’s truly a shame that cameras can’t have negative ISO values so that I wouldn’t have to bring these with me. These filters are annoying, somewhat fragile, and ludicrously necessary for creating stunning images. ND filters can be forgiven for leaving horrific color casts on your photos. ![]() If you took multiple photographs to make a panorama, make sure to adjust the white balance before combining the photographs. This process is fairly straightforward and will give you good results most times with a couple of tweaks. After this, you may need to make some minor tweaks to get the right balance. Select an area that should be white, like a cloud, or the rapids in a stream to automatically adjust the white balance. The easiest way to remove the color cast from an ND filter is to use the Auto White balance selector in Adobe Lightroom. So how do you get rid of ND Filter color casts? Luckily, these are usually fairly easily taken care of in Lightroom. Even top-of-the-line ND filters will create a color cast in your images. If you’ve recently come back from your first trip out with a new set of ND filters, one of the first things to jump out will likely be the horrendous colors that are taking over your images.
