In the interest of sharing positive experiences with the narrowband fast track tutorials I just wanted to say I am loving the potential control that image blend and selective color correction provide. With my focus now on more wider angle nebulosity images one of my goals is to enhance the sense of three-dimensional reality through the use of lighting, contrast, texture and transparency. I've had a very good run of imaging the last month with wonderful weather here in Las Vegas and have a few subjects that really open my eyes to this kind of enhancement. I've only done a little with some basic tools but I can see the potential of what these two tools will provide me in the future. I'm attaching 2 images I feel very good about. I think these kind of images really lend themselves to creating a depth experience for the viewer.
