Just a final few things to finish the image.A shadow cast by her cap and shoulder are the final steps. Using quick mask I painted on a shape guessing as to what the shadow should look like and added a color picked up from an area in the dark space between the red louvers. I reduced the opacity of that layer to 65% and had to add some yellow (edit> Color Balance) to get it the correct hue.I repeated that sequence to create the shoulder shadow. There would be no shadow cast on the shaft of the vent since its not close to her.The area of her boot showing a portion of her leg was retouched to remove the last remaining evidence of her body.At this point I checked the entire image for anything that may have been overlooked in previous steps and to remove anything in the original that should be retouched. I found a few spots here and there on the shirt.As you can see, the drawing element, as shown on her shirt interior, is basically simple. While some of you may not have tried this sort of thing before it will just take a bit of trial and error practice to master it. I hope this will have been some help to those of you asking for some advice on doing an invisible. While theyre all a bit different, this example contains most of the issues in a basic invisible.
