Layers

Filters and adjustments

Samples

Download layers sample images for in-class use (will be used for layers practice).

Download curves sample images for in-class use (will be used for curves control).

The cow's ear in this example is a good test of your layer masking abilities. Download Layer mask sample file for additional practice.

🔰 Practice task: Filters, smart objects, adjustment layers

Download the filters and adjustments sample files.

Submit all files at the specified pixel dimensions, resolution and file type. Do not delete layer masks - leave them in place.

Make sure to pay close attention to file names.

Note: this is a practice task, not an assignment. You are expected to demonstrate a basic understanding of the techniques, but there is no expectation that you spend much time refining your work.

  1. police-box.arw - Use a smart filter and layer mask to blur the background of the photo, making it appear that the background is out of focus. Do not use the blur tool in the toolbar; blur only with filters.

    Save in PSD format, 300 ppi. Do not change the number of pixels. Save file as YOURLASTNAME_task2-image-01 and make sure it has the correct file extension for the file format required.

  2. sunny-street-raw.arw - Using layer masks and adjustment layers, improve the exposure in the image for best visibility. The aim is to improve it - you will not be able to completely overcome the poor exposure. You will need build layers and layer masks to isolate the sky, street and buildings and apply separate curves to each.

    Save in PSD format, 300 ppi. Save at print size that will fit an 8x10 inch page - image should fit with or height but may not fit exactly in other dimension. Save file as YOURLASTNAME_task2-image-02 and make sure it has the correct file extension for the file format required.

  3. amusement-spin.jpg Fix the dirt (dark splotches), use curves to improve the brightness and contrast, crop, straighten (if needed) and then save in JPEG format at maximum quality. Save for use in a 4k 2160p video, which is 4096 pixels x 2160 pixels. As this is for screen use, PPI is not relevant. Save file as YOURLASTNAME_task2-image-03 and make sure it has the correct file extension for the file format required.

Check all files in Photoshop (resolution, etc.) before submitting.

Submission:
Upload each file file to Brightspace. Due by 6 pm, Sun, Oct 20.

Write in the Brightspace submission notes: for each image, does the image you have submitted have more, fewer, or exactly the same number of pixels than the original provided files?
