Lightroom's Graduated Filter - not just for skies!

Lightroom-Thumb

When you’re accustomed to using something, it’s easy to forget that its capabilities might stretch beyond just that for which you usually use it. You get into some sort of rut don’t explore whatever it is that you’re using, whether it is your food processor, your mixing desk, or your copy of Lightroom.

Jamie Gladden got in touch with us to tell us about a rather nifty way of putting Lightroom’s Graduated Filter to better use than just applying it to skies. Jamie, it’s over to you…

I recently posted an article on my blog describing some simple portrait retouching techniques using Adobe Photoshop Lightroom. A friend of mine later commented to me that he wasn’t that familiar with some of the Lightroom tools that I’d mentioned, so he’d go off, find some tutorials, and play around with these new toys. Great! There are loads of cool tutorials out there, and he’ll definitely learn some useful techniques which will improve his photo retouching skills.

One of the tools I wrote about was Lightroom’s Graduated Filter, which was introduced in version 2 and is very handy. If you do a Google search for this, you’ll find lots of useful tutorials explaining how to use the tool to pep up your landscape shots, darkening a bright sky to add more detail and produce a more even exposure without changing the area of land beneath the sky. Cool! So that’s a new technique we’ve learned, the Graduated Filter is used to even up the overall exposure of your landscape shots by darkening the skies, just like using a Neutral Density Graduated filter in front of the lens on your camera.

What if you don’t shoot that many landscapes? You’ll never need to use that filter, right? Maybe, maybe not. It’s easy sometimes to get stuck with the idea that some of the features serve one purpose only, but with a little experimentation, you can find new and unexpected things to do with them.

In my own photography, I tend to photograph bands and people more than I do landscapes. If I’m working in a studio, then I’ll have full control over the lighting, and the light goes mainly where I want it to go – most of the time! Sometimes, I’ll need to make minor post-production tweaks here and there to compensate for areas which are a little brighter or darker than I’d like.

Take a look at these two photos.

The top shot is complete up to the point at which I was happy with all the retouching and post-processing work I’d done, apart from one thing. I thought that the model was just a little too bright on the right side of her face and neck for my liking. The main light is coming in from camera right, and I had a fill light off to the left, and it’s the main light which is doing the damage.

I wanted to tone this down a little, but only on the slightly brighter area on the right side of her face. Decreasing the exposure or brightness isn’t really an option, because that would change the exposure/brightness of the whole shot, and that’s not what I wanted.

I could also have used the adjustment brush to paint over the too-bright areas, and then adjust the brightness level which would change only the area I’d painted over. That would certainly do the trick, and it does give you more control, but it can be a little fiddly sometimes, and would take more time.

But wait! What about the Graduated Filter? Couldn’t we use that to give us a subtle darkening of her skin on one side which is too bright without darkening the skin on the other side of her face? Definitely. The grad filter is perfect for that.

You can see the effect in the second photo. It’s quite a subtle difference, but for me it was necessary to fix it. After selecting the grad filter tool, I dragged the crosshair across the photo from right to left, stopping when I thought I’d arranged the markers in the correct position.

Then, I adjusted the grad tool’s exposure setting down to a level that evened up the lighting nicely, and I was happy.

Here’s another example. This is Alice:

If you’re working outdoors with natural light, then it’s not so simple to move the light source to where you want it to be, so you have to work the light to your advantage, and maybe use a reflector or diffuser to shape the light how you want it. Again, there will usually be some tweaks needed in post-production.

In the first photo, the background in the bottom left is just a touch too bright for my taste, and I think it draws your eye away from her face. Just a quick application of the Graduated Filter, as before, and it was fixed. Simple and quick. Which leaves you more time to go out and take photos, rather than sitting at the computer.

For a final, and more dramatic example, here’s a shot of Benjamin Curtis from the band School of Seven Bells:

When you’re shooting bands on stage, you’re totally at the mercy of the stage lights, which often change quite rapidly. Often, I like to make the lights a feature of my shots, rather than using them solely to illuminate the artist.

In the first photo, the lights are quite overpowering, and they detract from the shot, but by just simply adding a grad filter straight down from the top of the picture, we’ve toned it down a lot, and produced a really cool and striking effect from the stage lights.

So, there are just three examples of using Lightroom’s Graduated Filter, and not a single sky has been prodded. One of the real selling points of Lightroom for me is that it’s easy to experiment like this, safe in the knowledge that if it doesn’t work out, it’s so simple to go back to your original RAW file and start again.

This article was written by Jamie Gladden. Jamie’s a freelance photographer based in London, UK, with interests in music, fashion and portrait photography. He’s passionate about music and loves discovering new bands and artists. He reckons that there’s nothing better than seeing a really talented unsigned band in a cramped room above a pub. He’s similarly passionate about photography, and there’s no greater pleasure for him than being able to combine the two. Check out his site; 3 songs no flash.
