The writing below is just the introduction. I will post the papers that have all the steps required to complete the project. Please go through all the papers that will be uploaded to do the project correctly. Follow the instructions and then check if it is exactly what the criteria require.
The Purpose:
Recreate processes by which astronomers create impactful images of astronomical objects — both informative scientifically and visually pleasing — from multiple source images taken by observatories in specific wavelengths of scientific interest.
Extend this method to create a “multi-channel” image of a subject of personal interest or significance.
Your Task:
Begin by reading some background information, reviewing the meaning of color in a scientific sense and its importance in creating images of astronomical objects that are both informative and aesthetically pleasing.
You will create a set of images — three, total — assembling in each case an image built from (at least) three separate source images, with each source assigned to an individual color channel. The suggested software to use for this assignment is Adobe Photoshop (part of Adobe’s “Creative Cloud” suite, available free for registered PSU students, staff, faculty). Other Photoshop-equivalent applications certainly exist (such as, GIMP, Pixelmator,, etc.), and you may use one of them instead if you are familiar with them; however, instructions will be provided for completing the image creation using Photoshop.
For the first image, the combination of the source images should yield an overall composition that is “readable at multiple wavelengths” to a trained eye, for information relevant to elements or processes occurring strongly at one wavelength versus another.
The second image will involve adjustments to the first. The astronomical object contained therein need not change. You will just be trying out different color assignments and visual weights, according to personal preferences.
The third image is a composition of your own, representing a subject (or subjects) of personal significance — a kind of visual essay. You get to create a new “multi-wavelength” image of your own using multiple images based on your interests (does not have to be astronomy). You might think of it like, “What could someone learn about you, by observing in different wavelengths?”
Along with these image creations, you will answer a few short questions about your selections and interpretations of the images. Include these images and text in a single document, to turn in on the Project 3 Submissions page.
Criteria / Grading:
You will be responsible for downloading & installing, or otherwise acquiring access to Adobe Photoshop — or an equivalent program.
Photoshop is available free for Penn State students as part of Adobe’s Creative Cloud suite. A short guide to getting Photoshop is included in this module. You may also be able to find it pre-installed to use on a campus lab or library computer.
If you are unable or would prefer not to install a new application on your computer at this time, the site (Links to an external site.) offers a free Photoshop-like interface and image-editing tools. The site has a “login / account” section, but you do not need to do so; you can use it for free without signing up for anything.
Your image creations and answers to some questions will be combined and submitted online (Canvas) in a single document, similar to that for Project 1 or 2. A checklist and rubric on the Project 3 Submissions page will help you be sure you have covered all the essential points. This will be due by Friday evening, 24 June 2022.
Be sure to allow time for acquiring a copy of Photoshop (if you choose to). Acquiring the license through Penn State, downloading & installing, takes a bit of time.
Alternatively, the site (Links to an external site.) can do basically everything Photoshop does, but without needing to download or install anything on your own computer. The few differences between “Photopea” and Photoshop are pointed out where applicable in the instructions pages.
Again please pay attention to the steps follow each step everything you need to do will be on the papers uploaded.
