Image Editing and Photo Manipulation


Some editing of techniques are considered acceptable, for example enhancement or correction of color or contrast. If someone's hair is out of place on an otherwise good photograph, one might argue that it is acceptable to edit that hair.

We generally understand that advertisements are doctored in order to present idealized beauty and absolute perfection – such as in the Dove Evolution ad or Julia Roberts' in this Lancome ad. Take a close look at those models in ads for beauty products. Could anyone possibly have skin that flawless? Most likely not. The author of Astropix.com puts it beautifully:
"Today's viewers however, are very sophisticated visually. They know full well that anything, literally, can be done to an image. They have seen dinosaurs and aliens portrayed with lifelike realism in the movies. Problems arise though because viewers expect to be fooled in the movies, and tend to get upset and feel betrayed when they are fooled in an allegedly factual medium such as the news business."
Photos composited and manipulated in Photoshop (Wikipedia)


Let's get an introduction to image editing and photo manipulation from Wikipedia: 
Photo manipulation is the application of image editing techniques to photographs in order to create an illusion or deception after the original photographing took place.[1] A mere enhancement or correction is known as retouching.
Types of digital photo manipulation

In digital editing, photographs are usually taken with a digital camera and input directly into a computer. Transparencies, negatives or printed photographs may also be digitized using a scanner, or images may be obtained from stock photography databases. With the advent of computers, graphics tablets, and digital cameras, the term image editing encompasses everything that can be done to a photo, whether in a darkroom or on a computer. Photo manipulation is often much more explicit than subtle alterations to color balance or contrast and may involve overlaying a head onto a different body or changing a sign's text, for examples. Image editing software can be used to apply effects and warp an image until the desired result is achieved. The resulting image may have little or no resemblance to the photo (or photos in the case of compositing) from which it originated. Today, photo manipulation is widely accepted as an art form.
There are several subtypes of digital image-retouching:
Technical retouching Manipulation for photo restoration or enhancement (adjusting colors / contrast / white balance (i.e. gradational retouching), sharpness, noise, removing elements or visible flaws on skin or materials, ...)
Creative retouching Used as an art form or for commercial use to create more sleek and interesting images for advertisements. Creative retouching could be manipulation for fashion, beauty or advertising photography such as pack-shots (which could also be considered inherently technical retouching in regards to package dimensions and wrap-around factors). One of the most prominent disciplines in creative retouching is image compositing. Here, the digital artist uses multiple photos to create a single image. Today, 3D computer graphics are used more and more to add extra elements or even locations and backgrounds. This kind of image composition is widely used when conventional photography would be technically too difficult or impossible to shoot on location or in studio.
Photo manipulation alters the content of the images in a devious manner. It becomes difficult for the audience to differentiate between a manipulated image and reality. But Photoshop's popularity has proven to be divisive. While some laud it for its ability to allow subjects to look their best in a photograph, others see it as a vehicle for feeding our culture's desire for ultimate perfection. Manipulated images are created to deceive the audiences and form their understanding on how the media presents everything with perfection.[11] Therefore, with digital democratization[vague] increasing at a rapid rate it[vague] is creating problems. Since more people have access to technology it[vague] creates curiosity in the readers mind when they see an image published in newspapers or magazines. The reader begins to question the ethics of the publication which results in a debate. Photo images were considered as a reliable source and were known as a medium of communication to present the truth to the media.[2]


Fraudulent Photography, aka "Fauxtography"

This photograph is a dramatic example of deceptive photo manipulation or "fauxtography" — a fraudulent photo designed to deceive its viewers.


In August of 2006, Reuters news agency released this photo which had been altered to appear more sensational than the original. The photographer, Adnan Hajj, had used the clone stamp tool to make a column of smoke appear darker and larger than in the original, unretouched photo. It created an outrage — not only in the media community but also by news consumers around the globe — which resulted in the pulling of all Hajj's photographs from Reuters' services, and the firing of Hajj and his editor.

Creating and Maintaining a Portfolio for Employment

A portfolio is a tangible representation of your education and work experience. It is an organized collection of your work which will allow you to demonstrate to a potential employer your strengths, skills and achievements, and an expression of your special qualifications and unique abilities. Use it to show a potential employer why you are the right person for that job or internship.

A portfolio can contain, but is certainly not limited to:
  • Your resume
  • Letters of recommendation or commendation
  • Transcripts
  • Class assignments
  • Photos of projects or displays
  • Outlines of lectures or presentations
  • Photographs of yourself at work
  • Transcripts
  • Certificates of achievement
  • Academic recognition
  • Examples of brochures, handouts, flyers, etc. you've created or helped create
  • Samples of your writing
  • Examples of hobbies or special skills
There are two types of portfolios: traditional and digital. A traditional portfolio is a physical organizer such as a three-ring binder, presentation folder, artist portfolio or zippered case. A digital portfolio can be on a website or a CD. And you don't have to choose between the two, although it might be best to start with the traditional portfolio in order to begin organizing your collection of documents. Then use it as the basis for a digital portfolio (see below).

Create your portfolio by collecting anything that relates to your academic or work experience. Collect everything (yes, everything, then organize it later). Keep your collection of documents current by adding to it as your experience grows. Then when it comes time to organize you'll have a good selection to choose from.

The projects you will create in this class offer you the perfect opportunity to begin assembling an employment portfolio. In this class you will design and create several documents suitable for portfolio pieces. These assignments allow you the opportunity to create portfolio pieces to exhibit your creativity and ability to use Adobe CS software.

Next, organize your portfolio to demonstrate your abilities and achievements. There are many different ways to organize your collection including chronological, topic or subject (such as grant writing skills or photography), and lesson or ability (such as teamwork or communication). Depending on the type of case or binder you choose, organize each item in individual sleeves or pages. Be sure to include a brief, descriptive caption for each item (the exception might be documents such as your resume, letters and transcripts). Use tabbed and labeled dividers to separate sections and keep everything neat and tidy. Add to it as you learn, grow and create new projects; clean out older projects that don't represent your current level of ability or interests.

When the time comes to go to an interview, customize your portfolio for the specific position. Filter out unnecessary documents and include only that which pertains to the particular skills needed for the position. For example, if the job or internship requires public speaking, be sure to include proof of your ability, such as an outline of a presentation you have given or a photo of yourself addressing a group. Limit the size of your portfolio, maybe to 15-20 pages. Also, remember that portfolios are a reflection of the individual. In all my years I've never seen two that are alike and there is certainly no single "correct" way to assemble your portfolio. It will represent your personality and unique abilities.

Finally, you can present your portfolio during your interview. Be sure to inform your potential employer that you have a portfolio of related material that you can bring to your interview and ask what material might be important to bring. Check the University of Wisconsin-River Falls' portfolio website for more excellent tips on how to put together a portfolio and how to present it at an interview.

Digital Portfolios

Digital portfolios are the new normal and include a variety of media including CDs, DVDs and websites. Potential employers can view these in advance of your interview. In the case of online portfolios, employers can search the internet looking for a person with your qualifications and contact you via email through a link on your site. Portfolios that are sent to a potential employer on CD or other portable media are considered "disposable" as they may not necessarily be returned to you.

Digital portfolios are created in much the same way you would your traditional portfolio --- collecting, organizing and customizing --- but instead of compiling everything in a three-ring binder, work is documented electronically (for example, scanned documents, digital photos or PDF files) and compiled so they can viewed on a computer. Many website hosting services make it easy to create your own site even if you don't know anything about building websites (Behance.com, for example). Your digital portfolio can also be in the form of a CD, DVD or Power Point presentation. Keep in mind that the format should be cross-platform (compatible for both PCs and Macs) and industry-standard platform or software (html, PDF or Power Point).

Trace Over a Photo to Create Vector Art

Create vector art by using it as a template and trace it in Illustrator.

Open an image in Adobe Illustrator

It can be a bitmap or vector image. We're going to use this bitmap image of a Califoria poppy.




Think of this image in terms of its component shapes, not as the thing itself. Look at each petal, sepal and stem.What colors and shapes do you see?

Begin tracing with the pen tool

Let's begin with the large petal first. Use the pen tool to create a vector shape based on the shape of the petal.

Continue to trace the shapes...




Add fills to your paths

When you're finished tracing, use the Swatches or Color palette to add colors to your illustration.


You can choose to leave or remove the strokes from your illustration. Here I chose to remove the strokes and add gradient fills.


Open both the Color palette and the Gradient palette. Select the object (one of the petals, for example) and apply a gradient fill by clicking on the gradient. Illustrator's default gradient is white to black.


Change the color of the gradient
  • Click on a tab on the gradient ramp, adjust the color in the color palette (you might need to convert a grayscale black to a CMYK or RGB color)
  • Or drag and drop a color to a tab on the gradient ramp


To change the direction of the gradient, choose the Gradient tool, then click and drag across the selected object. Change the blend point by moving the middle slider. Additional color tabs can be added by clicking on the ramp. Adjust color as above.


Vector beauty!
