Smoke Photography

If you started shooting photographs using DSLR then at some point of time you would like to do few more experiments like capturing Water droplets & Smokes. Let's see how smokes are captured and manipulated in Photoshop to create some lovely photographs.

Requirements:

1. Camera mounted on a tripod (to get sharp shots)
2. Incense stick to create smoke
3. Black background (used to capture smoke trials clearly and reduce lot of time in post processing)
4. External light source (External flash is recommended, but I used simple table lamp with CFL bulb)
5. Remote control for shooting (optional)

Setup:

Keep the incense stick in between the Camera & dark background. Place external light source pointing towards the incense stick. Place the dark background at some distance so that the external light doesn't fall on the background. For reference see the picture below.



Experiment with various settings to get the smoke. Get some picture like the one below.




Post Processing:

There are several tools to create the effect we require, but I am going to demonstrate how you can do this with Photoshop CS2.

Step 1: Open the image in photoshop and crop the image if required

Step 2: Adjust the background so that it will be darker. This can be achieved by adjusting 'Levels' & 'Curves'. Another option is to use 'Selective Color' option with 'Blacks' & increasing 'Black'.

Then you will be left with the image as shown below:



If you just want to create colors with this image then you can proceed to Step 5. Otherwise, if you want to be a bit creative then follow the below procedure.

Step 3a) Rotate the picture by 90 deg by choosing 'Image --> Rotate Canvas --> 90 CW'

Step 3b) Duplicate the layer by Select --> Duplicate Layer

Step 3c) Flip the image horizontally/vertically by selecting 'Edit --> Transform --> Flip Horizontal/Flip Vertical' - this will create the top layer in opposite direction

Step 3d) Select Marquee Tool and starting from the top of the image, drag downwards to the middle of the image and press 'delete' to show the image below. Now you will have an image something like the one shown below.



Step 4) Now the last step is to color the image. This can be done in several ways, but we are going to do the coloring by gradient tool. For that first select 'Layers --> Flatten Image'

Step 5) Select 'Gradient Tool' from tools palette and select 'Radial Gradient Pattern' and choose a foreground to transparency fill. Use 'overlay' blending mode.

Final image.

Hope this gives an idea to create smoke trials. If you have any queries please post on comments section, I will try to answer.

Add Border using Photoshop CS2

There are few more important things other than taking photographs. One of the main thing that will come to your mind is how to add border to the photographs. There are few utilities which will do this job for you, but you won't be having such customized options. In this post we will see how we can add border using Photoshop CS2.

Step 1: Open the image you want to add border

Step 2: Click Image --> Canvas Size. It will show the current image size. (Don't forget to uncheck the 'Relative' checkbox then only it will show the current image size).



Here the image size is 800 x 537. I need a 20 pixel border and now we should add 40 pixel for height and 40 pixel for width. You can select color for the border by clicking the small rectangular box location near the 'Canvas extension color' dropdown. Now you can see a 20 pixel border is added around the image and the current dimension of the image is 840 x 577.

Step 3: But we don't want to disturb the image's original dimension's so we need to resize the image to 800. This can be achieved by clicking the Image --> Image Size and enter 800 in the Width text box. The image will be resized accordingly.



People who are happy with this border setup can skip the rest of the tutorial. Other people who want to make some more effect in border can proceed.

What if you want to change the border color? Follow the steps to change the border color.

Step 4: Select the image by pressing Ctrl + A. Click Edit --> Stroke. A popup window will appear. Enter the desired settings like Border, Color and the direction to paint. As we already know we have a 20 pixel border, enter 18 pixel in the width and select 'Inside' and the color 'Black'.



Now the image will have an 18 px border and 1 pixel while line between the image and the border, which will give you a decent look.
