Several have asked "How'd you do that?!" in my photo thread. I thought I'd put together a quick step-by-step of what I'm doing in Photoshop, to help explain how much is being done post-process, not just with the camera.

First, the photo has to have something to start with. I look for decent sharpness primarily, then also something to work with as far as composition. The photo I used for this is sort of disappointing because I cut off the tang's tail, but we'll go with it anyway.

I've resized the photos for Web presentation, obviously, as the Canon 20D I took these with takes 8.3mp photos.

Here's the raw, unedited original. This was taken with a few standard steps I always use.

1: Shoot perpendicular to the glass. Always. Glass distorts.
2: Underexpose just a little bit. -2/3 EV
3: Use a tripod.
4: Fire away with TONS of shots, this is digital, you're not wasting film. This same afternoon I took about 100 shots of a rose-headed wrasse, and still didn't come out with anything good. I probably took about a dozen shots of this tang, but he wasn't moving around much. This one was the sharpest.

Unedited:

So then, the first steps I took was to crop the image. I'm generally looking for a good balance, and a focal point. In this case, it's the eye. I also use Photoshop's AutoBalance feature, which is pretty accurate about 99% of the time. I'll tend to tweak the colors just a tiny bit later, but AutoLevels is usually a pretty good place to start.

Crop and AutoLevels:

Next, I "Clean up the junk." I use the Heal Tool primarily, but also some Blur and Stamp Tools. I rub out all those little specks and water debris. On this shot, the owner had a little bit of coralline on the glass, also, which I removed. The differences are subtle, but you can find them. Removing the specks and scratches helps eliminate visual distractions.

Clean the Junk:

Once I have a clean image, I go through and make color corrections. Here, I brought just a hint of the blue back (to help with the underwater look), as well as a slight overall brightness bump, to make up for the underexposure. I also do some dodging/burning here, though I never use those two tools. I'll select dark areas and bring them up a little, or bright areas and bring down the brightness a little. You have to be very careful here, as you can create a lot of grey and washed out areas very quickly.

Color and Brightness:

Finally, I resize the image (I tend to use 800 pixel width for Web), and sharpen and add a border. I sharpen with the Unsharp Mask dialogue (Filter/Sharpen/Unsharp Mask). There are three sliders here: Amount, Radius and Threshold. Two of these are *ALWAYS* the same, radius and threshold.

Radius is always 0.3 pixels. Any more, and the halo/glow effect gets out of hand. If you can't sharpen enough with a 0.3 pixel radius, the image didn't have enough to work with in the first place.

Threshold is always 10. This just gives a little room for error (overuse of the tool) and helps remove the harshness out of the tool.

The other slider, Amount, is in percentage. I find myself in the 200-400% area most often (range is from 0-500%). This particular photo happened to be 382%.

Then I add a border to help with the focus of the subject. Different people have different methods and colors. I use straight black and white. I Select All, then go to Edit/Stroke and use white with a pixel width of 7 pixels, on the inside. Then I go back to Edit/Stroke and use black with a pixel width of 6 pixels. This creates a 1 pixel wide white stripe surrounded by a 6 pixel wide black. It's just what works for me. Totally preference.

very nice tutorial ... I probably do 80% of what you do with my photoshop :)

What version of photoshop do you use? I have version 5, not sure it accepts RAW images though.
 
I have PS7. Oh, and I'm not pulling in RAW files, I'm sorry. They're just the unedited jpgs. When I used raw, I was thinking more along the lines of "uncooked, not done." :)
 
Great thread man! Which camera do you use? I'm in the market for a new camera and there is someone on RC that uses a Kodak with amazing results. I've never really been into photography until I started to try and take shots of my tank, it's tough to do. Great write up!
 
Really good info. I've never used photoshop before and I may give it a shot. My camera definately has to change, but I will try your tips with my current camera just to see how much better I can get some pics to come out. Thanks for the info...
 
wwoou dood

Underexpose just a little bit. -2/3 EV
3: Use a tripod.

could you just explain me what does that mean?, please.
i have a cannon 4.0 pixels and well i used to have the photoshop in my computer but right now my computer is down :( and well my sweet heart:mad: lost the cd program :( .
I'm gonna try finding it :) , but this is a great thread dood because i was always wondering how people take those awesome pictures.
 
I keep running into the problem that I can't get a sharp picture without the flash. My camera doesn't have a manual shutter control, but I can control the EV and a few other minor adjustments. Any tips on how I can get a sharp picture without the flash?
 
Gabby - check out this thread, too: Reef Photography Workshop.

I use Photoshop Elements, as the regular Photoshop programs were out of my price range. Now...if I could take a decent photo.... :). Great thread!
 
And this had the possibilities to be a Jiddy thread *lol*, i can tell from your guy's pcitures compared to mine that you are hoarding the secrets, come on, out with the techniques
 
Alright, here's another. I picked this one because it needed color correction, and I feel that's probably the most important part of why I use Photoshop.

Here's the unedited shot.

First things first: Crop and Auto Levels. I attempted to bring the hermit further toward the bottom of the frame, to give him some "weight." It also helped show how the Rule of Thids can help an image look so much more balanced.

Photoshop's Quick Mask is highly misunderstood and underestimated. Imagine you have a particular area you want selected. In this case, I wanted the background selected, and not the hermit. I used the largest brush, so it would have the softest edges. With this brush, I simply painted on the areas I wanted to have as the selection later.

When I exit Quick Mask, the area I painted is the area that's NOT selected, so I simply do a Ctrl+I (select inverse) and I've selected the area I painted. I selected this area because I wanted to mute it down, to help the hermit stand out as the main subject. I brought down the brightness with the Levels toolbox (Ctrl+L). In the image, I showed what happens when you slide the slider way down. In the end product, however, I only brought it down to 0.88, not 0.52, as shown.

Then I tweaked the levels just a little more, to make things seem a little less "purple." This is also done with the Levels toolbox. Occasionally, I'll use selective saturation controls, shown here. Open the Hue/Saturation toolbox (Ctrl+U). In this case, I wanted to pull some of the magenta out of the hermit's legs, and make them more red. In the drop down menu up top, select the appropriate channel (in this case, Magenta). You'll notice that as you move the cursor over the image, it becomes the Eyedropper tool, for selecting colors. To be more specific, as I did here, you can select a specific color and tweak that color. In this case, I used the eye dropper to select the upper right area of the legs, which appeared more blue than the rest of the legs. Then I slid the hue slider over to make the legs the appropriate red.

Finally, there's the unsharp mask. The most important part of the Unsharp Mask is not to overdo the radius. I never, ever, ever (ever) go beyond 0.3 pixels. Any more, and you start creating false halos and weird effects. If the image can't be sharpened enough with 0.3 pixel width here, it's not a good enough photo to begin with. I also make sure I set the Threshold to somewhere between 5 and 10, so eliminate freaky anomolies from sharpening. With those two sliders set, use the Amount as much as you'd like.

Add a border, resize to 800 pixels wide, and you're set!
