Photo Editing using Photoshop
Untitled-1.jpg

Adobe Photoshop is the premier photo editing software tool available. Whether you are working on a webpage, Powerpoint presentation, or a document to be printed, Photoshop can be used to enhance your images.

Have a look at this video to understand the basic photoshop tools.

INTRODUCING THE LAYERED COMPOSITION

We will look at Photoshop’s most powerful image creation tools “layers”. Every digital photograph or scanned output begins life as a flat, no layer image file. In photoshop, this flat image is called background and is logged inside the four walls of the always rectangular canvas. When we move one image into another, the moved image becomes a floating layer. We can move, scale or rotate a layer without adversely affecting the other. I will show you how to create one such composition. Welcome to the power of layers.
We have 6 different images as follows:

Swirls

swirls.tif

Paper art

paper%20art.tif

Grunge stucco

Wood grain

White wall

Yosemite fog

STEP 1: Firstly, we will combine big swirls image with paper art. In the swirls image, press ctrl+a (select all) , then press ctrl+c(copy) and then open the paper art image and press ctrl+v. In the select menu, click 'free transform' to scale or reposition the image.

STEP 3:Now to remove the white space from the swirl, press the magic wand tool and then click on the white portion. To remove all of the white spaces, press configure. Press the 8 key to reduce the opacity of the image to 80%.

STEP 4:Now to choose a particular size of frame press select, then click load selection and then press ok .Now to contract the selection line inward, press select and then modify, contract and add the number of pixels(200). To reverse selection, go to select and then press inverse. Press ctrl+alt+j and it will layer the selection to a new layer. To give dimensions to the frame, press fx and then click drop shadow and add your modified effects. Now we have created a picture frame.

STEP 5:Now copy the wood grain image to the picture frame and then rotate it 90 degree cc.(edit –transform –rotate). Rename it to wood grain. Now in order to place the wood grain only to the frame, go to the layer menu and press clipping mask. To change the colour, press fx and then click colour overlay. And here add the changes. Change blend mode from normal to colour .

STEP 6:Press ctrl+alt +j and tick the dialogue box. And then adjust the swirls by the moving tool. To colour the wall press fx and then colour display. Choose your colour and select multiply.

STEP 7:Now I will take the other two images and again create 2 more clipping masks . You can turn the layers off or on and we have a layered composition. Now this is our final composition which is the result of 6 independent layers.

Playing around with different tools of photoshop was fun. Here are some things we learned.

BLENDING TWO IMAGES TOGETHER

STEP1: For this we made use of the Multipy blend tool in layer mode.
First we open one of the images and make the background transparent using the add alpha channel tool in photoshop. Now using the 'Erase' tool to erase the background of the first image.

STEP2:Next we open the background image. Now we open the first image using the 'open as layers' option.

STEP3:In the second layer we select the layer mode as 'Multiply'. And its Done!!

CREATING BOKEH EFFECT

Another thing that fascinated us was the bokeh effect we saw on one of the websites. So we decided to replicate that using photoshop.

STEP1:For this we first used the bucket fill tool to create a plane black background. A new layer is then added. Using the Gradient Tool with Radial shape and opacity set to 50 and violet as foreground colour, we created the effect as shown. Another layer is then added. Then we used the circular brush tool followed by Gaussian Blur to create the following effects. In this case we use white 'Bucket Fill' to make circles.

STEP2:The above step was then repeated to get the following result. But unlike the last step, Gaussian blur was not used. This creates white circles which give a nice overlapped effect.

STEP3:For the final rainbow effect we created another layer and then used the Gradient tool on Full saturation mode. Opacity is reduced to 50 and pressure is varied. Also we change the layer mode to 'Overlay'. This gives us the final outcome.

ADDING EFFECTS TO AN IMAGE

1. Use quick selection tool to select area to be modified, in this case the sky area. Photoshop intelligently selects the area based on colour and texture.
2. The Adjustment layer can be added and used to tweak the contrast and brightness of different areas of the image.
3. The gradient option gives various desired effects to the selected portion.
4. Deleting an object from the picture is quite easy in photoshop. First, select the area to be removed and then select 'fill' option from 'Edit' menu.
5. Next, make sure you have selected the 'content-aware' option. Then the photoshop works on it and removes the undesired object. Sometimes, better results are obtained on performing the function more than once.

The Photoshop software provides a plethora of options for modifying an image. And when used along with other softwares like lightroom, it can produce stunning effects. From simple editing to making complex changes, one can do it all on Photoshop.
