In a previous tutorial, we looked at the benefits that the raw file
format has over JPEG when capturing images with our camera. We learned
that our camera's JPEG conversion process acts like a mini photo lab,
developing our images according to how it thinks they should look, with
no input from us, while at the same time discarding much of the original
image information that was captured by our camera's sensor. What we end
up with is an already developed image, with permanent changes already
made to its pixels, and with a lot of (what would have been) useful
image detail missing and gone forever.
A raw file, on the other hand, contains every bit of image detail
straight from the camera's sensor with no processing of any kind so we
can develop the image ourselves from scratch according to how we,
not the camera, think it should look. Not only do we gain complete
creative freedom over the process, but the abundance of image
information means we can often rescue and restore detail in the
highlights and shadows that, as a JPEG, would most likely have been
lost.
We also learned that in order to process raw files, we need to use a program like Adobe Camera Raw.
Yet Camera Raw can also be used to edit JPEG and TIFF images, leaving
many people wondering, "Which should I use for editing my photos -
Photoshop or Camera Raw?" In this tutorial, we'll answer that question
by taking a quick look at where Camera Raw fits within a standard image
editing workflow, as well as some of the advantages Camera Raw has over
Photoshop for developing and processing your images.
What Is Camera Raw?
There's no question that Photoshop has become the world's
most popular and powerful image editor, but one thing Photoshop can't do
on its own is process raw files. If you remember from a previous tutorial,
raw files contain nothing more than the raw image data captured by your
camera's sensor, with no processing of any kind (which is where the
name raw comes from). To work with these files, we need to use
special software that knows what to do with the raw data. Adobe came up
with two great solutions. One is a completely separate, standalone
application known as Adobe Lightroom. The other is a free plug-in for Photoshop itself - Adobe Camera Raw
- that ships and installs with Photoshop. Lightroom is a standalone
application (it needs to be purchased separately) that includes
additional features to help with your overall workflow, like the ability
to catalog your photos. Camera Raw is strictly an image editing
application. However, both Lightroom and Camera Raw use the exact same
image processing engine, which means both are equally capable of giving
you fantastic results.
Like Adobe Lightroom, Camera Raw gives you everything you need for processing raw images.
Camera Raw Or Photoshop? Which Is Better?
Camera Raw was initially built for raw image processing,
but over time, it has evolved to include the ability to process JPEG and
TIFF images as well. So which should you use for editing your images,
Camera Raw or Photoshop? The simple answer is - both! Think of Camera
Raw as an image developer, while Photoshop is an image editor.
First, we open the image in Camera Raw for initial developing, much
like we'd process a film negative in a darkroom. Then, once we've
processed the image and it's looking good, we can open it in Photoshop
for further editing and refinement.
In a Camera Raw/Photoshop workflow, Camera Raw is where we
do all of our initial processing work - setting the overall white
balance, exposure, contrast, and color saturation, adding some initial
sharpening, reducing noise, and more. In general, you can think of our
work in Camera Raw as global edits. That is, edits that
affect the entire image as a whole. Once we have the overall image
looking the way we want, we can then move on to Photoshop for more
specific local edits which is where Photoshop excels.
As we'll see in other tutorials, it's certainly possible to do some
local edits using the tools in Camera Raw, but in general, Camera Raw is
all about making the initial overall image look good. Of course, it's
also possible to do global edits in Photoshop using features like Levels
and Curves. So what makes Camera Raw so special?
Streamlined For Image Editing
Photoshop has become so big and powerful over the years
that what started out initially as a program for editing photos is now
used not only in the world of photography but also in practically every
creative field imaginable, including graphic and multimedia design,
video editing, 3D rendering, even medical research! You could almost (almost)
argue that Photoshop is now overkill for editing images, not because it
can't do everything you need but because, as a photographer, it can
also do a whole lot more than you'll ever need. For a
photographer who's new to Photoshop, all these extra abilities can be
confusing. They make learning the program more difficult and time
consuming than it needs to be, and with no clear indication of where to
begin once an image is open on the screen, you can easily be left
wondering, "Now what? Where the heck do I start?"
Camera Raw solves this problem. Even though it's a plug-in running in Photoshop (or in Adobe Bridge
- more on that in another tutorial), it looks like a completely
separate program, a program that was built with photographers in mind
and streamlined for photo editing. It's organized in a logical format
and structure that follows a standard image editing workflow, so there's
no guesswork needed on where to begin. Like Photoshop, it uses tools and panels
to help you develop and process your images, but they're presented in a
simple, intuitive, easy to understand layout. And unlike Photoshop,
Camera Raw isn't cluttered with features that as a photographer, you'll
never need. So that's advantage #1. For photographers, Camera Raw is
just easier to use.
Panels like this one make processing images in Camera Raw simple and intuitive.
Non-Destructive, Flexible Image Editing
Photoshop itself is what's known as a pixel-based editor. What this means is that as we work on a photo, Photoshop makes changes to its pixels. This is called destructive editing because it alters the original image information. The opposite of pixel-based editing is parametric editing, and Camera Raw is a parametric image editor. Parametric editing is non-destructive because it uses nothing more than a series of instructions (called metadata)
to tell the software application how to display the image on the
screen. As we process and develop an image in Camera Raw, it records and
saves all of our settings as a list of instructions (basically, it
takes notes) and what we see on the screen isn't really the edited
image. Rather, it's a live preview of how the image
looks based on the current instructions. If we move a slider or change
an option in one of the panels, or use one of Camera Raw's tools to
alter the image in any way, Camera Raw simply updates the instructions
as well as the live preview, so we can see how our changes are affecting
the image without actually applying the changes to the image!
The important thing to understand is that with Camera Raw,
the original photo and the instructions on how to process the photo are two completely separate things.
No changes are ever made to the original image data. All we're doing is
saying to Camera Raw, "Show me what the photo would look like if I
increased the exposure, or boosted the color saturation, or converted
the image to black and white. How would it look if I cropped the image
as an 8x10? What about a 4x6 or a 5x7? Can I get away with a little more
sharpening? What if I add a vignette effect?" We give Camera Raw
instructions on how to display the image using its tools and panels, and
we can change these instructions as many times as we want with
absolutely no loss of image quality. In fact, no matter how much
processing we've done, we can revert back to the original photo at any
time simply by clearing the instructions and starting over!
Of course, there are ways to work in Photoshop that are
non-destructive, like duplicating an image, using layers, adjustments
layers, Smart Objects, and more. But Camera Raw is non-destructive by
nature, so there's no need to worry about it. It's only when we go to
open the image in Photoshop for further editing, or we save the image
out as a JPEG or other file type, that our Camera Raw instructions are
actually applied to the pixels in the image. Until then, Camera Raw's
non-destructive editing ability gives us all the freedom and flexibility
we need to make our photos look their very best.
No matter what we do in Camera Raw, the original image remains unharmed.
Easily Edit Multiple Images At Once
Another big advantage with Camera Raw is that you can easily edit multiple images at once,
something that's not possible with Photoshop. If you've taken multiple
shots of the same subject, or in the same location, all under similar
conditions, you can easily select the images in Adobe Bridge, open them
all at once in Camera Raw, then after processing one photo, you can
instantly sync all of your settings with the other images, saving you
lots of time and effort!
Additionally, you can copy and paste Camera Raw settings
from one image to another directly from within Adobe Bridge. You can
apply the settings from the previous image to your new image, and you
can even save your settings from one image as a preset which can then be
applied to other images without having to redo any of the work!
After processing one photo in Camera Raw, you can instantly synchronize the settings across multiple images.
Camera Raw - A Faster Way To Work
When you combine all these advantages together - that
Camera Raw is streamlined for photo editing, that it's completely
non-destructive, and that you can edit two or more images at the same
time - you come up with an undeniable fact. Camera Raw is just plain
faster than Photoshop. The intuitive, logical way its tools and panels
are presented allow Camera Raw to feel almost second nature, and because
it's a parametric editor, using nothing more than instructions to
display a live preview of the image, there's no render time! Every
change we make with a tool or panel happens instantly for us on the
screen. Add in the ability to sync, or copy and paste, settings from one
image to another (or many others!), as well as options for saving
images as JPEGs or other file types directly from Camera Raw itself, and
you have a powerful, highly efficient and easy to use image editing
application, whether you're working with raw files, JPEGs or TIFFs - an
application that would be worth every penny if it wasn't absolutely free
as part of Photoshop!
To quickly sum things up, the question about Camera Raw and
Photoshop isn't which one you should use, but rather, which order to
use them in. Camera Raw isn't out to compete with Photoshop and doesn't
replace it. Both have their strengths and knowing when to use each one
is the key to an efficient workflow. Camera Raw should be your starting
point, your digital darkroom. It's where all of the initial developing
and processing of the image takes place. Then, once we've done
everything we can to the image as a whole in Camera Raw, we move it from
the darkroom into our main image editor, Photoshop itself.
