Milestone Report Step 6 (Step 6.) Open a new image and compile the three or four images into one “color” image.)

Once the images “K” values are balanced you can begin to compile the images into one color image. Start off by opening a new file. Make sure that the new image is in RGB color and that the resolution is the same as the images. Copy the images into the new file, I suggest using the rectangle tool to copy and paste the images into the new file. The images need to be pasted in the following order Red, Green, Blue, (and if available) and Luminance. Then each image needs to be copied into there corresponding channels.

Click on the RGB channel and then click on Layers. Delete the background it’s not necessary. Next switch the Layers from normal mode to screen mode. This must be done for each layer. The next step is the “curves”. To change the curves press, “Control +M”. Change the curves so that they intersect the grid at the points (1,2) and (2,3). Below is an example of what the grid should look like. Your image may look blurry but that’s okay. You can get rid of the “noise” with the next step. After changing the curves you need to change the levels. To do this, press the buttons “Control +L”. You want to move the far left cursor located below the graph as close as possible to the black vertical line without cutting into the line. Cutting into the line will cause you to lose parts of your image that are valuable to your pictures quality. (Before) (After) After completing this you will want to go back to the curves and fix any changes that have occurred. Be sure to do all of this for every layer of the image.
