Video: Light Leaks

I always find it a little bit amusing that when we're applying effects that simulate vintage cameras for example, we're essentially in many cases adding effects that represent things that we tried to avoid in the past. So, for example, we might add film grain when most photographers, at least many photographers that I know. Would want to avoid the appearance of film grain in most of their images. And light leaks are certainly an example of something that we very much try to avoid in film photography.

Light Leaks

I always find it a little bit amusing that when we're applying effects that simulate vintage cameras for example, we're essentially in many cases adding effects that represent things that we tried to avoid in the past. So, for example, we might add film grain when most photographers, at least many photographers that I know. Would want to avoid the appearance of film grain in most of their images. And light leaks are certainly an example of something that we very much try to avoid in film photography.

Light leaks would occur from a variety of circumstances. A common cause for example would be the film door on the camera opening when the film had not yet been rolled back in to the cartridge for example. So, let's take a look at how we can simulate those sorts of light leaks for our images within analog effects pro. The process is very simple, I'll start off by clicking on, Light Leaks so that I can expand the set of controls that are available there and I'll also collapse the loop and histogram display, so that we can see a little bit more of the controls here that are available.

And those controls are very similar to the presets that we use over on the left panel. They are thumbnails that represent the particular shape, the appearance, of the lightly that you can add to the image. And so all you need to do is click on a Thumbnail. And you can add that particular effect to the photo. We also have a pop up where we can choose among various categories of light leak. So, for example, we have some soft light leaks. I'll go ahead and apply one of those effects here. And you can see that we have this very soft wash of colour essentially going across the image, versus the crisp options that we were looking at just a moment ago.

I'll go ahead and select one of those, and you can see that we have a little bit more crisply defined area of that light leak. And then finally, I'll go ahead and choose the dynamic option, and here you see we have light leaks that represent some degree of motion or change across the image. So, perhaps there was some sort of light source or the. Almost partially covered as so we have this variable effect throughout the photo. So, not all of the photo gets the same effect and we see a degree of transition.

So these are the slightly more exaggerated or dramatic effects, I would say, in most cases. Once you've found a particular type of effect that you would like to apply in terms of that light leak, you can also fine tune the strength. I recommend that you start with the strength setting at the maximum value of 100% so that you can better see exactly how the effect works within the image. And then once you have a sense of the overall effect. For tha particular option you've chosen, you can reduce the strength of that effect based on your own personal preference.

So, for example, I'll go back to the crisp option and select the first light leak that we had taken a look at. And you see at 100% we have a very strong effect. But I can tone that down so it's just a little bit more subtle effect. If I drag the slider all the down to zero of course then we see no effect at all. We can also move the effect around within the image. So, once I feel that the shape that I've selected and the overall strength is where I'd like it, then I can mouse over the image and you'll see that I have this little handle.

That I can use to drag the effect around within the image. Now, I can't just place the effect anywhere within the image. In this particular case, for example, I can't place this light leak into the center of the image. But I can move it around, for the most part, determining the degree to which it is visible within the image. But if I drag further up, for example, you'll see that we get a little bit of an effect along the bottom edge of the image. I can drag that down to eliminate that effect. And so I can just fine tune the overall position.

I'll go ahead and choose one of the more dramatic effects here. Let's take a look at this one for example. And then, I'll move my mouse over the image and now you can get a better sense of the ability. To really move that effect around within the image. Whether you want to use the effect to block a portion of the photo or to make sure it's not blocking an important subject or so that the effect appears in a portion of the image where it will be most visible or perhaps more subtle. The point is that we can move that effect around within the photo, so the basic process is very simple.

We can choose among the various categories of light leak effects, then choose the thumbnail for the specific effect we'd like to add to the image, and fine tune the effect by adjusting the strength slider as well as moving the shape around within the image
