In photographic circles, Adobe Camera Raw has become quite a hot and popular topic. There's so much excitement about raw capture and raw processing. Yet sometimes, some of this is a little bit mysterious. It's a little bit confusing. So what I want to begin to do here is to distill things a bit. The first thing that we need to do is take a look at two terms, raw capture and raw processing. For starters, raw capture has to do with how we're actually capturing the image on camera. On the other hand, raw processing is all about using Adobe Camera Raw.
Well, let's define these even further, starting off with raw capture. Well, whenever you capture an image with a digital camera, the image is captured on the sensor. If you're capturing in JPEG mode, that then information goes through a whole sequence of steps here, Bayer Interpolation, White Balance, Contrast, so on, Compression. Then we get to JPEG. On the other hand, we can capture a file in its RAW format. In other words, the information simply comes straight off the sensor. And we have all of this RAW data.
So in this scenario, we're talking about raw capture. Now in contrast, when we talk about Adobe Camera Raw, we're talking about something completely different. This has to do with how we process an image in software which is called Adobe Camera Raw. So, one of the things that happens when we're using Adobe Camera Raw is that we have these actual pixels. We have image information. Well, we then apply a set of instructions to these actual pixels. The instructions are actually interesting. They're simply a laundry list of information which describe how we want this image to be displayed, whether the crop or the color.
So what happens then is this set of instructions displays an image in a particular way. Now the nice thing about Adobe Camera Raw is that working in this context, it's completely nondestructive. In other words, no pixels are harmed. No pixels are affected. We're not actually pushing pixels per se. Rather, we have pixels that we're applying some instructions to, which then in turn display the image perhaps in a different way. This in turn gives us a lot of flexibility. And we can always undo what ever we've done.
This can also really speed up our overall workflow. Because if you think about it, with Adobe Camera Raw, there's no render time, because you're not actually doing something to pixels. Rather, you're simply changing the set of instructions. Here you can see I have another version of this image. The other thing that's interesting about Adobe Camera Raw is that we can process images, whether they're RAW, DNG, TIFF or JPEG, in this format. So we're not limited to just working on files that were captured in the RAW format.
Rather, we can use these different types of formats. All right, well, if we had to distill this, how would we do that? Well, think of Adobe Camera Raw as a way to nondestructively edit and work on your photographs. What it does for you is it helps things to be a little bit more flexible, because you can always undo whatever you've done. It also will really speed up your overall workflow, because while working in Camera Raw, there's no render time. There's really no save time. So, it speeds things up by leaps and bounds. Lastly, I like to think of Adobe Camera Raw as not only being functional, but also very creative.
It can really help you process your images in some interesting ways. All right! Well, now that we know a little bit about Adobe Camera Raw, let's go ahead and take a look at it and we'll do so in the next movie.
