Colour Replacement

1) LESSON: BASIC COLOUR REPLACEMENT TECHNIQUE

2) PROJECT: COLOUR REPLACEMENT (PHOTOSHOP)

3) ADDITIONAL INSTRUCTIONS IF COMPLETING AT HOME (PHOTOPEA)

Your teacher will run you through the basic steps in changing the colour of a subject. (hint: it involves using masks!)

The sequence is as follows:

- Add a Hue/Saturation adjustment layer. (This automatically creates a mask as well).

- Change the colour of the entire image to what you want the subject to look like.

- Use the brush tool (B) with either black or white ("Black reveals and White conceals") to mask out areas whose colours you don't want to change.

2) PROJECT: COLOUR REPLACEMENT (PHOTOSHOP)

You are to hand in the tutorial image (sofa) AND another image that you either took yourself or found in the Internet.

For the second image, choose one (or a few) element(s) whose colour you will change using the methods in the lesson above.

i.e. CHANGE THE COLOUR OF THE SUBJECT IN A IMAGE.

Popular examples include cars, clothing, furniture, food, etc. Remember, you're not changing all of the image's colour, only that of your chosen subject(s).

CRITERIA & RULES!!!

Tips for choosing a suitable image:

• Your goal is to change the colour of part of an image, not the whole thing. So be sure that your subject / object (i.e. whatever is going to change colour) is a decent size in the frame. The image should be in proper focus and correctly exposed (not too dim or too bright).

• Popular examples include cars, clothing, furniture, food, etc. Remember, you're not changing all of the image's colour, only that of your chosen subject(s).

• Please avoid the following:

  • Hair: There’s a more complicated process for that that I hope to teach you later.

  • Subjects that are white, grey, or black (including reflections). These are difficult to change realistically using the simple method I’m showing you this week.

• Your image must be a natural environment photograph with a real background (not a stock photo or studio photo with an all-white or all-grey background. That’s too easy!

• Your colour change should look realistic. The choice of colour might be absurd, but your image should not look obviously Photoshopped.

ADDITIONAL TIPS:

- Be aware of the hardness of your brush. You may want a hard brush for crisp, defined edges; OR you might want a soft brush that blends more subtly.

- If your subject is a car, be careful that the wheels, taillights, windows, etc. don't take on the changed colour. Use masks everywhere!

HANDING IN:

1) Save your AFTER images as a .jpg. Give it a a different title (e.g. "Sofa AFTER") so we know which is which.

2) Upload your BEFORE and AFTER images (both the tutorial AND own choice) directly to Classroom, complete the rubric, and TURN IN.
