Color certain part of the photo

Want to make your photo fancier? Here is a little useful trick

This is the original image:

Image

If we want to color only the flower and make the rest black and white, it will look like this:

Image

 

 

Open the image and select ‘Pen Tool’ from the tool barImage, the select ‘Path’ from the function window at the topImage, and draw along the figure of flower like this

Image

 

press ‘CTRL+ENTER’ to select the area you just drew, and then press ‘CTRL+SHIFT+I’ to select the counterpart

Image

 

Duplicate the background layer to get background layer copy, then select ‘<Image –> Adjustments –> Hue/Saturation>, a window will pop up and enter the data like following

Image

 

Now your image will look like this:

Image

You are done for now, but if you want to further change the color of the flower, do the following:

press ‘CTRL+SHIFT+I’ to counter-select the flower part, and get the window for ‘Hue/Saturation’ again( A fast way to do this is to press ‘CTRL+U’)

If I want the flower in bright color, I will enter the data as following

Image

 

Notice the color of flower changed? Press ‘CTRL+D’ to cancel selection, and you are done!

Image Histograms: What are they, and why are they important for digital images?

IMAGE HISTOGRAMS

Image histograms are ubiquitous to digital images. You’ve probably seen them on your camera or any photo editing software. In this tutorial, I will be showing screen shots of image histograms from Adobe Photoshop

How do I find the image histogram in Photoshop?
To find the histogram that shows the various RGB colors, go to Window (top navigation bar) > Histogram
To find the histogram that shows the various brightness values of the colors, go to Image>Adjustments>Levels
**I will do a tutorial following this one that describes how to use Levels**

Basics:

What is an image histogram?

Every color in a digital image has a brightness value ranging from 0 (black) to 255 (white).
An image histogram is a histogram of brightness values of every pixel in an image

Tones and Tonal Ranges

The tonal range is the region of the histogram were most of the brightness values are present.

Image
This is a standard histogram of brightness values
Image
This is a color histogram

What can an image histogram tell you about your image?

Lighting: is my image High Key or Low Key?

High Key Image: an image in which most of the tones are in highlights

Image
Notice how most of the pixels are found in the highlight region of the histogram
ImageImage

Low Key Image: an image in which most of the tones are in shadowsImage
Notice how the pixels are mostly found in the shade region of the histograms
ImageImage

Overexposure of image: is my image overexposed?

An overexposed, aka clipped, image may have regions that are overexposed to the point that they are solid white and no detail can be seen.
Notice how the top left corner of this image is clipped.

Image

This image’s histogram will show that the brightness values for some pixels are pushed to the very edge of the chart:

Breadth of Tonal Range: How many tones are in my image?

An image that has a broad tonal range will have a high pixel count on the far left and far right side of the histogram.

Image

ImageImage

An image that has a narrow tonal range will have a high pixel count in one region.

Image
Most of the colors in the picture are a light yellow or pink.. this is why the histograms have only 2 main peaks.
Notice that this picture also has high-key lighting
ImageImage

Amount of contrast in image: How much contrast is in my image?

A histogram with a broad distribution of brightness values also tells you that there is high contrast in the image.

Image
ImageImage

On the other hand, a histogram with a narrow distribution of brightness values also tells you that there is low contrast in the image.
Image
Notice that this image also has low-key lighting.

I hope this tutorial was useful to you!
Now that you have knowledge of how to read an image histogram,

learn how to manipulate the histogram by using Levels in my next tutorial!

How to color a black and white photo using Photoshop

In this tutorial I will show you how to color in a black and white photo using Adobe Photoshop

Here is an example of an old wedding picture I colored in for someone:

Image

You can also create a funky image like this one:

WATCH THE TUTORIAL HERE (it’s 5 minutes long)

_________________________________

Don’t have 5 minutes?
Here are the basic steps:

1. Open image
The background layer is the black and white image that you’ll be coloring. Leave this layer alone

2. Create a new Layer

3. Change the mode of the layer from Normal mode to Color mode
To access this option, go to the Layers PANEL and look for the drop-down menu that says Normal.
Find Color in this drop-down menu and click on it to change the mode

4. Select a Color
The color you select is what it will look like when you brush it over a dark, almost-black shade

5. Use the Brush tool (B) to paint in the Color Layer you’ve created
Made a mistake and painted over something you didn’t want to? Simply use the Eraser Tool (E)

6. Continue painting until you’re done!

7. Save as a Photoshop document (.psd) in case you want to edit your color layers

8. For sharing, you’ll want to also save a FLATTENED copy of the image as a .jpg or .png or .gif, etc
Merge all the layers into 1 layer by selecting Layer in the navigation bar (up top) and go to Flatten Image
Save this file

Tips:
* Create new layers for each color, or segment of the photo
* To layer colors, create overlapping Color Layers and then adjust the Opacity of the top Layer
* Name your layers to avoid confusion!
* To make one piece of an image pop, only color in the aspect you want to highlight and leave the rest black and white!
