How to Add Color to Black and White Photos in Photoshop

If you have an old family photo in black and white, you'll love this tutorial. I will walk you through how to convert a black and white photo into color. First, let's take a look at both the initial photo and the finished product:




Step 1: Actually, the original photo was a little darker so I had to modify the level parameters. Go to ‘Image > Adjustments > Level’. A histogram menu will open. There are three parameters under the graph. To adjust the light level, I have increased the left value and slightly decreased the right value. The middle value remained unchanged. You can choose your values by adjusting the slider until you are satisfied. Lightening your image may make it a little easier to work with. Also, ensure your file is in CMYK mode.




Step 2: Next choose the selection tool. I like using the polygon lasso but you can use the normal lasso tool if you'd like. First, I'll concentrate on the skin. Select all of the skin including the face, hand, neck and shoulder. This will require patience, attention and perhaps a few attempts!




Step 3: Look at the photo carefully... I have selected her face but excluded her eyes, eyebrows and lips as those colors are different. To exclude any area of the selected face simply hold down the ‘Option’ key while using the Lasso tool. To add other areas like the hands and shoulders hold down the ‘Shift’ key. After all of the skin has been selected, press 'q' on your keyboard. This will unleash the quick masking option which will turn all other areas pink. Touch up areas of the skin that are pink using the eraser. To smoothen the mask add a little gaussian blur effect and then hit ‘q’ again.




Step 4: Next, go to ‘Layer > New Adjustment Layer > Curve’ or click on the half black circle icon beneath the layer panel and select 'Curve'. This will create a new layer. In the dialog box, name the adjustment layer as 'Skin' and check the box to use the previous layer as the clipping mask. When you hit ‘OK’ a new graph box will appear. Click the drop down menu beside the text ‘CMYK’ and select every color one by one. Change the shape of the curve so that the graph will look like this:




When you click ‘OK’ you will see the magic! His/her face has changed into color! Of course, you will need to adjust the curves in the previous step according to the skin color you are trying to achieve.




Step 5: Now that we've covered the basic, you can follow the same method to colorize the hair, lips and clothes. For every each set of uniquely-colored items, create a new adjustment layer and modify the color curves accordingly. For her hair and lips, I have used these two settings:




Step 6: Because I want her hair to have have blue hair and brown lipstick, I've raised the blue curve for the hair layer and raised the red curve for the lips with a mix of black. My final photo looks like this:




That concludes this tutorial. Best of luck bringing your black and white photos to life with color!



How to Tear Up a Photo in Photoshop


Did you know that you could add a torn up effect on a photo with Photoshop? In this tutorial I will show you how to do this!

Step 1:

I picked up the photo of Lee Major to tear up. Duplicate the layer and select the blending method as ‘Screen’. The image should look brighter.




Step 2:

Double click on the duplicated layer to open the ‘Layer Style’ window and click on ‘Drop shadow’. Choose the blending mode ‘Multiply’ and lower down the opacity. Now add ‘Inner Shadow’ and ‘Inner Glow’ effects; use multiply blending mode, low opacity and black color. Now click on ‘Bevel and Emboss’ tab and set the depth to 13% and the shadow mode to ‘Lighten’. Follow these screen shots for guidance:













Step 3:

Now find some images of torn paper and cardboard from Google images and place them in your Photoshop document. I have used three images and placed them like so:




Step 4:

The way we lay out the torn paper outlines how the photo will be torn. Click on ‘Layer 2’ in the layer panel while holding down the ‘Control’ key and the shape of the torn paper will be selected. Now click on ‘Layer 1’ or whatever layer contains the photo. The selection is now covering the area of the photo; press ‘Control + X’ on your keyboard to cut the area and paste it on top of all layers.




Step 5:

Follow the same method for the other torn papers and cut the photo according to the shapes.

Step 6:

Now select the layer on top and double click it to open the ‘Layer Style’ window. Add a drop shadow effect and repeat the same effect for other layers that contain parts of the photo. You can also add some Gaussian blur effect to the torn papers in order to lighten the background. The photo seems a little too bright so I also placed a new level adjustment layer on top and darkened the photo. My final image looks like this:




Tear away!

[HowTo] Know if someone is stealing your WiFi

We had written about configuring WiFi properly in your home. Now, we will cover the security aspect of a WiFi connection. Most of the people do secure their WiFi with WPA-PSK keys. These keys are hard to break , Again it is always good to know few things which we will be covering in this tutorial.
How to know, If some one is stealing your WiFi?
The key here is to understand the router LOGs These log files are updated automatically by the router firmware , when someone connects your network, does a admin login etc.
First, open your router admin page . Most of the admin pages can be accessed by writinghttp://192.168.1.1 in any browser. Make sure that your modem is connected to your PC via LAN or WiFi.
Few modems have address http://192.168.0.1.
Enter username as admin and password as admin. If the login fails, then try with the blank password.
Once you are able to open the router configuration page, open the connected devices link. This link usually appears in the front page itself.
Navigate to the attached devices, and have a close look into the list. Example :
The attached devices must be your computers, devices that are connected to network. Keep a count and then cross verify.
How To know the failed connection attempts?
Again, in the router configuration page , you can find direct link to open the log.
In the log file, if there is something like “connection rejected“, it means that , the device with the listed MAC address , is trying to connect to your WiFi .
What to do next?
Well, if someone is already connected to your WiFi network, first thing you need to do is to change your WiFi password. And wrong password attempts does not cause any trouble.
