How to Color Black and White Pictures using Photoshop in 10 Easy Steps

Suppose you have a Black & White picture and wish to add a dash of color to gray, there would be no need for you to run to the nearest studio. Instead, you can just use Adobe Photoshop right from home! It is simple enough to be carried out in 10 easy steps that I will demonstrate right now

Let’s say this picture is my B&W sample to be colored using Photoshop:


Here is how to go about the process:

Step 1: Right click on the picture in question and Open With Adobe Photoshop.


Step 2: Double click on Background in the Layers tab and make Layer 0.


Step 3: Now right click on layer 0 and select “Duplicate Layer”. This step is optional but I always prefer it as a precaution in case there is a need to go back to the original.


Step 4: Use the Polygonal lasso tool (circled in red in the picture below) to slowly and carefully select the area you wish to color.


Step 5: Once you have made your selection, click on Select from the menu bar and choose Feather. The box shown below appears. This option feathers the edges of your selection so that the color that you fill in does not look too artificial. Usually, 2 pixels works fine by me!


Step 6: Then go to Image -> Adjustments -> Colour Balance as shown in the picture. below A dialogue box controlling color levels appears. Keep shifting around the color balance till you get the color of your choice by changing the Midtones, Shadows and Highlights. Just in case you have different selections that need the same shade of color, I’d advise you to note the RGB color levels and just input these in the boxes each time. This will spare you from having to tweak around each time to get that perfect match!


Step 7: Once you’ve got the color you want, right click on the selection and choose “Deselect” from the pop down menu that appears.


Step 8: Use the Polygonal lasso tool again to select another portion of the picture that you want to color and repeat steps 5 through 7.


Step 9: When the entire picture has been colored (below) compare this with the original B&W picture. You can do this by making only Layer 0 visible (and not Layer 0 copy).


Step 10. Now that you are satisfied with your work, delete Layer 0 and save your new image with a .jpg extension (not the default .psd extension) by clicking on File -> Save As…

Here is the final colored image:


And this was the colored picture that I had taken using my Nokia 5220 camera (I had converted it to B&W using Picasa for the purpose of this tutorial):


They both look pretty similar right? Looks like a job well done!

You can use this simple coloring technique to create stylish color accented pictures or even color drawings and sketches. Enjoy!

How to turn your Canon Point-and-Click Camera into a dSLR with CHDK

CHDK stands for Canon Hack Development Kit. This is a free (released under GPL) firmware add-on to the Canon PowerShot firmware that allows you to modify your camera in unimaginablWikiy vast ways. For starters, this includes overriding shutter open-time (from 64s to 1/100K s, with flash sync), RHDRKaushik AW file capture, live histogram the kind found in really expensive cameras with RGB or ɣ overlay, customizable grids, user-written script support… and much much more.

In short, as the wiki homepage says, there are quite a few things that could not have been possible without CHDK: lightning photography, HDR (High Dynamic Range) photography and even unlimited DOF (Depth of Field) photography.

It does not damage or void the warranty of your camera in any way, since it is just a firmware add-on.DropKaushik There are quite a few tutorials on the wiki to put the CHDK on your Canon camera. In brief, here is a short tutorial.

  1. Remove your SD card from your camera.
  2. Connect the card to your computer (using a card reader) and format it – make sure you backup your old photos before this step! A better way is to use Card Tricks, format the card as FAT and make it bootable.
  3. Download the ZIP file for your camera from this page and extract the contents to root folder of your SD card.
  4. Safely remove the SD card, and lock it for write-protection this is an important step. The card must be write-protected, or CHDK will not run. This is a simple way to turn on, and turn off CHDK: remove write protection to use the default firmware, and lock it for writing to use CHDK.
  5. Enjoy your new firmware, but make sure you read the user manual (check which version you want); CHDK is daunting and confusing at first.

For older models, such as Canon A430 (my camera, basically!), download the DISKBOOT.BIN file linked in this forum post. Both the pictures shown in this post were taken/modified with my Canon A430.

Loading CSS Based on Screen Resolution Using Javascript

While working on the redesign of Techie buzz, I had several things in mind that I wanted to include in the design. One of the things was to make the design widescreen friendly by making use of a larger content area.


Throughout the design process, I asked several team members to test the design on different browsers. However, all the testers had one thing in common, they were all using widescreen monitors.

Once I rolled out the new design, one of my friends and fellow bloggers Deepak Jain sent me a message saying that the design was broken on his PC. On further investigation, I found that he was using a monitor with a max resolution of 1024×768 pixels. The new design did not particularly work well on those resolutions.

Now I personally did not want to change the width to just fit properly in 1024×768 resolutions. To overcome that I came up with a much better solution.

  1. I separated all the hardcoded width for the layers, and copied it to a separate file.
  2. I then created a copy of the new file, and modified it to work in 1024×728 pixel screen resolution.
  3. I then wrote a conditional Javascript to include the CSS based on the screen resolution of the user.

Doing this made the them work properly on both 1024×76 pixel and higher screen resolutions.

Here is the code that can be used to include CSS based on different resolutions.

<script type="text/JavaScript">
    var screenwidth = screen.width;
    if (screenwidth <= 1024) {
      document.write('<link rel="stylesheet" href="" type="text/css" media="screen" />');
    else {
      document.write('<link rel="stylesheet" href="" type="text/css" media="screen" />');

Have fun with your next design. If you want more such useful and interesting tips, don't forget to visit the section.

How To Restore The Original Flickr Logo [Scrape Off ‘From Yahoo’]

flickr-yahoo-logo Some days back, a slight change happened at Flickr. A small Yahoo logo was added to the Flickr logo so that it reads Flickr from Yahoo!. We say, it’s fine if Yahoo wants to remind people of that fact that it owns the largest photo community on the web; we are absolutely cool with it. But the fundamental fact here is that as techcrunch puts it – Flickr users, many of whom are techy hipsters, just don’t mix well with middle America Yahoo.

The change was met with a lot of criticism. People thronged to Flickr’s forums and tweeted how being owned by Yahoo is something to be ashamed of. Ultimately, it’s the company’s sole decision to select the way they wish to brand their products. If the Yahoo branding looks hip on your screen, that’s great; if not, let’s get a greasemonkey to do the job.

Flickr user,  aspherical element, must be really troubled with Yahoo intervening his place of tranquility. He picked up the task of creating a greasemonkey script that scrapes off the yahoo branding and brings back the original logo. If you follow the same league, get the Greasemonkey script here. As a necessary rule, you’ll need Firefox and the Greasemonkey addon installed (Or Google Chrome if you’re geeky enough to enable scripts)
