757 Newark Liberty Airport Canon EOS Digital Rebel / EF 70-200mm @ 200mm f-6.3 / 1/500 sec. / 200 ISO Shot RAW and processed via DPP. Additional sharpening, color correction and a frame added in PS CS2. I am slowly getting the hang of using PhotoShop CS2, and Canon's DPP. I have developed my own style of doing things called a "workflow". I am still learning and it changes as I learn better ways of doing things. My current workflow is as follows: Shot RAW and processed with Canon DigitalPhotoPro Brightness = 0.0 White Ballance = Cloudy Pic Style = Landscape Histogram levels adjusted for brightness and contrast Tone = 0 Saturation = 2 Sharpness = 4 Final Processing via Photoshop CS2 1 . I generally start with Auto: Levels / Color / Contrast, and if it improves things I accept it otherwise back to the original. In this case Auto levels made the sky a better blue color and Auto Contrast made no visible change so I kept it. Auto Color made things worse so I did not use it. 2. I used Shadow/Highlight tool to make some minor adjustments 3. I tried using the High Pass Filter on a new layer to sharpen the image. I do not completely understand how to get this to work. At the normal setting it made things a little sharper but also made things grey! even at 9% opacity it killed my contrast and at 9% not much sharpening was going on. I ended up using soft light at 35% opacity. This seemed to work. 4. I added Contrast +7 5. Resized to 700 pixels wide. Maybe I could do this a better way? 6. Ran a USM, 68 / 5.6 / 21 6. Added the black boarder 7. Saved for the web, Jpg - high The end.

Thi Yellow Tang was taken thought pretty think glass at The Deep. With a few clicks you can bring a soft-ish image back to being nice and sharp. Details are below! Remember let me have your comments. Did this tutorial work? Did it fall down at some stage? Sharpening a Photograph There are a couple of ways to sharpen a picture. One can be done by going to the filter menu and clicking on sharpen and selecting one of the sharpen styles. For this tutorial I will show you the High Pass filter which will allow you more control over the sharpening of the photographs 1.Open your picture and duplicate the background layer and call this new layer SHARPEN 2.With the SHARPEN layer selected go to the FILTER menu and select OTHER then click on HIGH PASS 3.Your picture will now turn grey 4.The slight edges of the picture that you can see through the grey are what will sharpen in the picture 5.Don’t have the setting too high a radius of around 5 pixels is more than enough to sharpen a picture without going over the top 6.Click OK 7.With your SHARPEN layer still selected change this from being normal to overlay – the drop down box is just above the layers 8.As soon as it is changed to overlay the sharpened image will now appear 9.You can change the opacity of this layer to control the amount of sharpening you wish to apply 10.Once you are happy flatten the image NOTE: You can only sharpen up photos that are pretty sharp in the first place. The sharpening works by looking at the edges in the picture and making those stand out. If you photo is blurred you will still have a blurred photo after.
