Welcome to The Helpful Art Teacher, an interdisciplinary website linking visual arts to math, social studies, science and language arts.

Learning how to draw means learning to see. A good art lesson teaches us not only to create but to look at, think about and understand our world through art.

Photoshop tutorial: Using the clone stamp to create a surrealistic pizza






For this tutorial you will need a subscription to Adobe Creative Cloud. We will be using the program Adobe Photoshop. You will also need to download the project files below. Just right click on each image of the plain pizza to open them up in a new window and save them in the highest resolution available. 


The video above goes into detail about how to cut our your toppings using the lasso tool and resize them using edit, transform, scale. 


The clone stamp enables you to pick up pixels from a different part of your image and paint with them. In this case we will be using the clone stamp to pick up the cheese from the pizza in the background layer:

You can adjust the size and hardness of your clone stamp, exactly as you would any other brush:


Then hover the cursor over the area you wish to clone and simultaneously click on the option key (if you are on a MAC) or alt key (for Windows) and the mouse. 



Now, unhide the top layer and click on it so that you are drawing in the top layer, hiding the edges of your surrealistic pizza topping (in my case an eyeball) with a clone of the cheese from the background layer.


Finally, play around with the blending modes to make the topping look like it truly belongs on top of that pizza.

You can play around with the various 'transform' features in Photoshop as necessary to rotate or distort the toppings. For more surrealistic experimentation in Photoshop try my 'fruit with faces' lesson here:

Adobe Animate 101: Creating Animated Graphic Symbols and Motion Tweens in Adobe Animate




Creating Animated Graphic Symbols and Motion Tweens in Adobe Animate


You will need a subscription to Adobe Creative Cloud to complete this lesson. We will be using the programs Adobe Photoshop and Adobe Animate. We will also be using the Adobe Media Encoder to export our animation as a video.

You will also need to download these four stick figure project files and the green screen color image. Right click on them to open them full sized in a new window before downloading them.





Below are step by step screenshots from the video above, with instructions.  These are meant as a supplement, to walk you through the steps after watching the video.


Unlock background and use magic wand to delete the white background on all four files. Save each image as a Photoshop file. Don't rename them.

File, Scripts, load files into stack


Use the ‘move’ tool to move all four figures on top of each other.

 Create Frame animation

Make Frames from Layers


Save as a Photoshop file. Name it ‘Walk Cycle Image Stack’

Open ‘Adobe Animate’ and create a full HD animation at 24 frames per second (You need to change the FPS)



File, Import, Import to Library. Import the ‘Walk Cycle image stack’ file.


Make sure all four layers are checked off and change settings to ‘convert layers to keyframes’


Insert ‘New Symbol’


Name the new symbol ‘walk cycle’. You want to create a Graphic symbol. In the library, click on the ‘walk cycle’ symbol you just created. This will put you INSIDE the symbol. In the library, open the folder called ‘walk cycle image stack’. Drag the first layer onto the timeline.

Right click on the frame on the timeline and click ‘copy frame’


Right click, ‘paste frame’. Every frame should appear twice in a row on the timeline. This will make the movements appear smoother.

On the next space in the timeline right click and ‘insert blank keyframe’ then drag the second frame in the walk cycle on to the timeline.

In order to be able to see where to position the figure, you will need to turn on the ‘onion skin’ feature (shown with the arrow in the picture above).
Position your second figure directly on top of your first figure, matching up the legs and head as closely as possible.
Position all subsequent figures directly on top of the previous one. When your animated graphic symbol is complete, it should look like a person walking in place, not a person walking forward. This is very important. You will create the forward path later, when you create your motion tween.

Once you have all the frames on the timeline, you will need to exit the symbol and return to ‘scene 1’ by clicking on the back arrow.


Drag the ‘walk cycle’ graphic symbol you just created onto the timeline so that it is just off the left side of the stage.

Right click on the timeline and ‘create motion tween’

Drag out the timeline to the 3 second mark

Drag the figure across the screen to just off the right side of the stage. This will create a motion tween.

 You will see a dotted line, showing the motion path. You can adjust the motion path by dragging the line. At this point you can test out your animation and you should see your stick figure walking across your stage. Unfortunately, the default background color, if you don't add in a background, is black. So if you exported the video now, you would barely be able to see it. We will be adding in a green screen colored background.

Click on the layer and ‘insert layer’ Drag the layer to the bottom.

 File, Import, Import to stage,
 Import green screen color to stage.  You have now assembled all the components of your animation. Name and save your 'Adobe Animate' file.
File, Export, Export Video.

Click the green arrow in the ‘Adobe Media Encoder’. This will convert your file to an MP4 video. 


Designing an original cartoon character

Think of personality traits you would like your character to have. How would you depict those traits in a drawing? Is your character young or old? An adult, teen or child? Male or female? What type of hair and clothing do you want them to have?


Now that you know how to create a walk cycle, an animated graphic symbol and a motion tween, and you have a basic understanding of how to use the 'Adobe Animate' program,
go back to the four 'walk cycle' images you saved in Photoshop. Add a layer to each file and, using the stick figures as a guide, for size, proportions and pose, create a walk cycle animation of your own, original cartoon character.

To download and use a greater variety of walk and movement cycle templates, click here:

Just right click to open the image full size in another tab, download, open in Photoshop and create your own original characters in the layer above the images, using the size, proportions and poses as a template. Then stack the images the same way you did in the above exercise and create your own original animations. 

Here is a detailed tutorial for creating a walk cycle of your own original cartoon character:

For instructions on creating the cityscape background, 
please click here:

For the project files, to get you started designing your original character, please click here:

Below are videos I have created for my computer animation classes on adding color to your digital artwork:






Once you have created and colored a walk cycle of your original character, save it as a JPEG. 
Open the JPEG, unlock the background, and delete the white background using the magic wand. Next, duplicate the layer 5 times. Erase all but one of the figures in each layer, so that each step of the walk cycle is in a different layer. Then move each figure so that they are all lined up, stacked exactly on top of one another. Then follow the same sequence of directions as above to create a walk cycle of your original character. Instead of using a green screen background, use the city scape image that you created earlier or create a simple background in Photoshop. 

The dimensions of your background should be 1920x1080 pixels, with a resolution of 300 pixels per square inch.

The Principles of Design and Composition





Instructions: 
Fill each triangle in the worksheet below with a linear pattern from the worksheets provided here



Below is a worksheet filled out by one of my students.


Next scan or photograph the finished worksheet and print three copies of it on white card stock. Using liquid watercolors, paint a different color scheme on each sheet.
Sheet 1: Every color you can mix using magenta and yellow
Sheet 2: Every color you can mix using magenta and blue
Sheet 3: Every color you can mix using blue and yellow

Next: Cut up all three sheets into the triangles and put them in an envelope for safe keeping. Use the triangles to explore the 9 Principles of Design and Composition by arranging them on a black background.














Here are a few more good videos on the Principles of Design:






The Principles of Design are Balance, Emphasis, Movement, Pattern, Repetition, Proportion, Rhythm, Variety and Unity.

Right click on the images below to open them full size in a new window. Using the worksheets and this blog post as a guide, create a series of collages with your triangles that express all the principles of design. You may use more than one principle in each design. In order for your design to be considered effective, other people need to be able to guess correctly which design principles your collage is addressing without you telling them.




Many students are confused by the concept of 'Asymmetrical Balance'. Consider the worksheet below. We know the chairs on the right are balanced (obviously, there can be zero debate about that because if the arrangement were unbalanced the chairs would topple over), yet the design is not symmetrical (it's not the same on both sides). 

How can a design be balanced but not symmetrical?

Often professional artists and designers will choose to use an asymmetrically balanced design over a symmetrical one because they wish to create a dynamic sense of movement in their artwork. The design on the right is more dynamic, while the one on the left is more static.






If you feel the need to review the Elements of Art, before plunging in to the Principles of Design, this series by KQED Art School is excellent:
