Transferring files and photos from your phone with Microsoft OneDrive
NSCAD students have access to Microsoft OneDrive, a cloud storage service. Students have one terabyte of space, which is enough to store tens of thousands of large images.
In many cases, the best way to move pictures from your phone to your computer or a NSCAD lab computer is to use OneDrive. The basic steps are:
- Install the OneDrive mobile app for iPhone/iPad
or the OneDrive mobile app for Android.
- You can then share pictures from your phone or tablet to the OneDrive cloud.
- Then, from a NSCAD lab computer or your own computer, log in to the OneCloud web interface. You can find this in the Office 365/Outlook toolbar at top left.
- You can then download any files your need onto your computer to open them in Photoshop.

Assignment
Assignment 2: Make a version
Start with a photograph that you took yourself.The photograph needs be your own work. You can create an image with a digital camera or phone. Then, create a new version of the original, based on one of the themes noted below. Make sure to save your original file and your altered file.
Remember: Images you use in this class need to be your own creation. Any exceptions to this will be noted in the assignment details I post for each assignment.
The unaltered image needs to be a single image you created. You many not use any other images as part of the assignment.
The version must be based on
one of the following themes:
-
Colour: Take a dull scene, and make it fun. Use colour, painting, moving and removing elements, and any other techniques you wish, as long as you follow the "General requirements" below. You can interpret fun broadly - whimsy, exuberance and cheerfulness all count.
-
Tend a garden
Start with a photo you have taken of an outdoor area with some plants. Using a range of tools in Photoshop, tranform the image into an orderly garden. Copy or clone out plants, recolour (with the Color Replacement Brush) foliage, trim, "replant" and rebuild into a nicer place. Remember, you cannot add other images - use Photoshop's image manipulation and painting tools instead.
-
Analog to digital
Start with a pencil sketch of a simple scene you've created on paper - it does not need to be elaborate, and the quality of your sketching is not important. Take a photo of it - or scan it, if you have access to a scanner. Then, using a range of tools in Photoshop, change it with colour, deleting or repeating elements, and any other techniques you prefer. Your sketch is considered the "original" for this option. Make sure to explore lots of different tools, and focus on altering the sketch rather than just drawing a new image in Photoshop.
Read all instructions carefully.
Failing to follow assigned instructions may result in lost points. You may not use any AI/artificial intelligence features for this assignment.
Technical requirements:
You must demonstrate use of most of the following tools as a
minimum:
- Clone stamp
- Dodge and burn
- Paintbrush
- Selection tools, including marquee and object select tools
General requirements:
- You may not use any generative AI features - such as prompt-based image generation.
- You may not use filters for this assignment.
- Don't be afraid to change the image radically from the original.
- Don't include parts of other images; that will be the next assignment.
- For this assignment, use a resolution 240 pixels/inch. Both your original and altered image should be set to 240 ppi. Your original and altered image should be each be set up to fit on separate 8.5 x 11 inch pages - either wide or tall orientation are fine.
Submission
Format: Save as Photoshop file. Filename: YOURLASTNAME_Assignment2a.psd for your original and YOURLASTNAME_Assignment2b.psd for your altered version.
In the Brightspace comments, note your "theme" (the option you chose),the pixel dimensions, (x by y pixels, the print size (in inches) and the print resolution in pixels per inch.)
Upload the two files to Brightspace by 6:00 PM,
Sun, Feb 01
Suggested procedure
- Don't put the assignment off - start soon and post any questions to the Slack #assignments channel.
- Spend some time choosing a theme and image that will work well together.
- Set the resolution and size of your original file to the assignment requirements, name it correctly based on the assignment requirements, and save it on your computer. Do not save in the "Cloud Documents" location.
- Next, using Photoshop's Save As... function, to save the file again, this time with the correct name for your "altered" version and begin to make changes to it.
- Review the checklist below and submit both files.

File types
Photoshop (.psd)
Adobe Photoshop format. Saves layers, masks, paths, and all other Photoshop data. Lossless. Primarily an editing format.
JPEG (.jpg/.jpeg)
Named after the Joint Photographic Experts Group, JPEG is a lossy file format - that is, it discards some data - and image quality - to achieve small file sizes.Primarily a distribition format.
GIF (.gif)
An 8-bit indexed colour format, limited to 256 colours, with 1-bit transparency (no partial opacity). Can be animated.
PNG (.png)
Several variants - PNG-8 is an 8-bit indexed colour format, similar to .gif. PNG-24 is a 24-bit colour format, with an 8-bit alpha channel (transparency mask)
