| This is because near the edge of the antenna, roughly half the lens aperture can still see past the edge of the antenna to pick up detail from the face behind it. | This is because near the edge of the antenna, roughly half the lens aperture can still see past the edge of the antenna to pick up detail from the face behind it. | ||

Here again is that full stack result. | + | When we process the full stack, details from both areas get shown in the final result, giving the impression that the antenna is partially transparent when it's really opaque.

| It would be great if the software were smart enough to recognize that the antenna is opaque and just handle the problem correctly all by itself. But it's not, so we have to help get a clean result through retouching. You //could// retouch by brushing the antenna from individual source images, but that gets incredibly tedious. There's a better way! | It would be great if the software were smart enough to recognize that the antenna is opaque and just handle the problem correctly all by itself.

| - | The better way is to use "Stack Selected" to generate stacked output for just those the input frames that have the antenna in focus, then retouch using the Stack Selected output as a source for brushing. That way we get to retouch from just one image using a big brush, instead of having to paint small details from each of the twenty or so source images that have different parts of the antenna in sharp focus. | + | The better way is to use "Stack Selected" to generate stacked output for just those input frames that have the antenna in focus, then retouch using the Stack Selected output as a source for brushing.

| Increase the brush size to cover pretty much the whole width of the antenna, and stroke over it to get rid of the background detail. | Increase the brush size to cover pretty much the whole width of the antenna, and stroke over it to get rid of the background detail. | ||
