How To Create Bokeh Using Photoshop

Before I start, maybe not all members understand what is Bokeh. Here is the elaboration of Bokeh:
"In photography, bokeh (pronounced /boʊ'kɛ/) is the blur,[1][2] or the aesthetic quality of the blur,[3][4][5] in out-of-focus areas of an image, or "the way the lens renders out-of-focus points of light."[6] Differences in lens aberrations and aperture shape cause some lens designs to blur the image in a way that is pleasing to the eye, while others produce blurring that is unpleasant or distracting—"good" and "bad" bokeh, respectively.[1] Bokeh occurs for parts of the scene that lie outside the depth of field. Photographers sometimes deliberately use a shallow focus technique to create images with prominent out-of-focus regions." -http://en.wikipedia.org

A big aperture give you a very good Bokeh. However not all photographers can afford to purchase these lens as it oftenly come with a high price.


Thanks to the software technology today, photographers are able to create their own bokeh without having big aperture lens. Today, I would like to share with fella members here a simple tutorial of how to create a bokeh with Photoshop.


What I have with me now is Adobe Photoshop Version 6.1 and a simple photo that I just took. Please take note that the objects are arrange in side by side manner just to give readers a better illustration.


1. Open the photo that you want to work on.




2. Choose the Rectangular Marquee Tool (M) and select the object.




3. Right click on your mouse and select Feather.




4. Select Feather Radius of 20 and click OK.




5. You can see radius on the 4 corners of your selection.




6. Right click and select Inverse.




7. You can see all your selection are inversed.




8. Go to Filter -> Blur and click Gaussian Blur.




9. Choose radius 8 and click OK.




10. Right click and choose Deselect.




So, here you go:


Before:




After:




All the settings that I presented here is just an example. You can set your own setting according to your taste. With this technique, you can compensate a Bokeh photo without getting a big aperture lens.


But why do you need Bokeh? Bokeh can make your object stand out and you can focus more on your object. Here are a few examples that taken by me using the same technique:


Pic #1. I want to focus to be more on the man's face and there's a chain behind his head. Therefore I blur out the background.




Pic #2. There are quite a number of distraction on the background. And I again, I blur it out to focus the man on the left.




So, hope this helps to all and enjoy shoting!

After looking at your shot, somehow you don’t get the sharpness that you desire. Then you start to feel disappoint with it.

1. Open the photo that you would like to sharpen.

4. You can choose RADIUS that your prefer. However as for me I have choosen 20 PIXELS.





5. Go to LAYER, select NORMAL and click OVERLAY.





6. The photo might be slightly oversharpen. But it's not a problem as we can reduce the sharpness by adjusting the OPACITY. I have selected 50% OPACITY.





7. The photo is totally sharpen. However there are certain area that you doesn't want to sharpen. You can do it by selecting ADD A MASK and you'll see LAYER 1 box there.





8. Go to SET FOREGROUND COLOR to black and click OK.





9. Select BRUSH and choose your prefer SIZE. As for me, I have chosen 200. Then you start to brush all the area that you doesn't want to sharpen. For me, I have decide not to sharpen the skin tone, therefore I have brush it accordingly.

Learn How To Stamp A Water Mark Logo On Your Photo

Worry of someone stealing your photo? One of the technique is to place a watermark on your photo. The most common watermark are wordings. But today, I'll share with you how to do it differently. Instead of wordings, I'll use a logo using CS5 software
1. Open the logo that you want. For me I've chosen my favourite logo, which is a Panda




2. Go to EDIT and choose DEFINE BRUSH PRESET




3. Open a new blank file by clicking CTRL N. Select BACKGROUND CONTENTS WHITE and click OK. (You can choose any background color that you want according to your preference.)




4. Once your background is WHITE, move your LOGO to the centre and click ALT + mouse RIGHT CLICK.


5. Open the photo that you want to have a watermark on it. Click on the STAMP symbol. Go to the STAMP box (on your left top corner) and choose the type of STAMP that you like. Since I have created the panda logo, therefore I selected it and choose SIZE 715 (this is where you can adjust the size of the logo), MODE NORMAL and OPACITY 100% (this is where you can adjust the contrast of your logo).







6. Finally the STAMP is ready and I have place it on my photo.



Here you go, my photo with a cool panda watermark
