Chapter 10: Cameras for Animation > Focus Incrementation - Pg. 187

Chapter 10: Cameras for Animation 5. 6. 7. 8. 9. 2 to frame 29. We now have used up an additional 28 out of 144 increments. Combining the second and third columns, we have used 58 out of 144 increments. Move one column to the right again and put down 26 1 4 -inch increments from frame 3 to frame 28. We now have used 84 out of 144 and have 60 increments left. Move one column to the right and put down 24 .25-inch increments from frame 4 to frame 27. We now have used 104 out of 144 and have only 20 .25-inch increments to use up. Move one column to the right and put down 22 .25-inch increments from frame 5 to frame 26. We now have used 130 out of 144 and have 14 increments left. Following this same pattern, we see that if we use frames 6 to 25 we have more frames than increments. In cases like this, all you need do is move to the right and put down a column of 1 4 -inch increments from frames 9 to 22 until we have used all 144 increments available. Here comes the easy part. To get your eases, add the increments from left to right to obtain the anima- tion increments. So frame 1 moves .25 of an inch, for frame 2 the camera will move .25 + .25 = .50 of an inch, for frame 3 it will move .25 + .25 + .25 = .75 of an inch, and so on until the there are fewer increments to add together and the ease out begins. If you add your final increments from top to bottom, you will see that you will indeed have the camera travel 36 inches over 30 frames with a smooth ease in and ease out. This simple and easy-to-understand system can be modified in any number of ways to create moves that are ease out only or in which one of the eases lasts longer than the other for more sophisticated moves. Depending on how you prefer to work, the moves can be
