Some types of editing, such as airbrushing, are done by hand and others are done using photo editing programs. Photos of models etc are edited to remove blemishes or make the model "better" or a photo is edited for fixing errors like red eye, contrast, brightness, etc. Photo editing is also used to make completely new images

Earlier, when manual photography system was there, the task was broadly categorized in to retouching and finishing. Retouching was performed on the photo films before taking print from those films and photo finishing was carried out after the photo in printed. Both the task was performed to produce a good quality photograph with all the desired modifications. Now a days, in the digital era, the task is now been carried out by Photo Editors before printing or publishing the image, as the case may be. The task of photo editing is still complex but with the use of software and enhanced features, it is a bit simpler than earlier manual methodology. Some photo editing is even done offline, on actual photographs, posters or other printed collateral. Photo editing is also knows as

Question :

What are various types of Photo Editing? Explain



Answer :

There are many different types of photo editing. Some are simple and others are more complex. For example, some photo editing techniques are done manually, while others are conducted through automated software. We can easily do simple photo-editing easily and quickly while complex photo editing and digital editing techniques may require specialized software program along with training and experience. It may be divided into three broad categories:

1. Simple photo-editing may include

Noise reduction: Noise is the occurrence of color dots or specks where there should be none. It is accomplished by reducing the pixel size to make the picture smooth. 

White balance: Is used to color of the light in the image

Contrast: Higher contrast makes an image more punchy, while lower contrast makes it flatter in color.

 Exposure Adjustment: The brightness of the image is adjusted. 

Color adjustments: Is defined as the change the color of an item or element in the photo. It may be background color or the component of main object.

Image Resizing: Image Resize is performed to adjust the dimensions of the image. Image dimensions are the length and width of your image, measured in pixels. For example, when you apply for a job, the recruiter ask to upload an image of 40x60 mm etc. 

Image cropping: Cropping makes the image to be in proper size or to remove unwanted parts. Crop feature allows to drag a rectangular shape around an area in the image to cut off the sides.

Background removal: It is used to remove or alter the background from the image to isolate the subject like white background etc.

Erasing: Means to erase areas within your image to leave behind transparency or a background color. There is also a Background Eraser which provides more control in removing a background to transparent.

2. Complex & advanced Photo Editing include:

Portrait corrections: Used to fix the complexion of people or objects in images

Special effects: Can be anything from animation to adding weather conditions like cloudy, fog or snow etc etc. 

Clipping paths: It is used extract a subject or element from an image. It may be a person or object also.

Adjusting text and visuals: We may add text and visuals or manipulate the existing one even remove them. 

Photo stitching: Technique is used to put two or more images together seamlessly to make it look like they were shot that way 

Drop and reflection shadow: It is used create or adjust shadows

Photo masking and Layers: It is used for hiding and revealing specified portions of an image

3. Pixel level editing and parametric image editing

Pixel level editing: Pixel level editing means if an image is altered at the pixel level. These changes are permanent as performed at pixel level and hence considered as a destructive form of photo editing because it’s not as easy to undo the changes and restore the original file. This feature permits to make extremely detailed editing to accomplish certain functions like CMYK color modes etc which other tools even parametric image editing can’t do.

Parametric image editing: In Parametric image editing(PIE), edits are recorded as a set of steps to follow to accomplish the final look. It doesn’t change the pixels of the image and is a non-destructive mode of photo editing. Mostly the high level editing is started with PIE, and then using pixel editing to refine the final details.

The features and techniques vary from software to software and a particular software may only provide Basic, Complex or Pixel editing or a combination of these categories of features. 



Question :

What is the use of Adobe Photoshop?



Answer :

Adobe Photoshop is among the best Photo Editing Software available in the market. It provides almost all the photo editing features from basic to advanced. It is simple to understand and use.

Question :

What are the most common color Formats



Answer :

RGB color - It lists a value between 0 and 255 for each of the {Red, Green, Blue} components of a color.

  • (0, 0, 0), the absence of color, is completely black.
  • (255, 255, 255), the presence of all colors, is completely white.
  • RGB is the most common color used

CMYK color – It lists a percentage of each of the colors {Cyan, Maroon, Yellow, blacK}. Color printer cartridges uses CMYK color. It is mostly used by the graphic designers to see how their work is going to look after it is printed choose, they convert their work after it has been done in RGB to CMYK so that they have a better sense. 

Grayscale – It’s a color mode that operates entirely in black and white.

Bitmap - Only allows for black and white dots (pixels);

 Lab color - It specifies a color using a 3-axis system. The a-axis (green to red), b-axis (blue to yellow) and Lightness axis or simply say represents color with 3 components: {Lightness, color value from red to green, color value from blue to yellow}. It is useful   Lab color - It specifies a color using a 3-axis system.

Question :

What are layers? Explain. 



Answer :

Ability to create and use multiple Layers within the same image is Photoshop’s most powerful feature. Layers are the key working platform in Photoshop, which are like sheets of transparency. As objects are placed on a layer, they become part of the layer, just as if you had drawn on a transparency with a marker.

A layer is one layer on top of another, all of which can be edited independently of each other and laid on topof or beneath one another, and then later combined to form a single, flat image.If two objects are on the same layer and you want to move them closer to each other, you need to cut them using the respective tools and physically move them. If they are on different transparent layers, however, all you have to do is move the layers with the move tool until the objects are closer to each other.

We start working with the “Background” layer when an image is created. We can’t use all effects on a background layer and to use various features, we have to create Layers.
