Lightroom :: Drawing And Writing In LR

I've been exporting my images to PS to add text, arrows and circles because of the generally assumed information that LR did not have graphic or text on image capability except for watermarking and print titles that can be JPEGed. Using an old technique with the local adjustment brush I found an easy way to do all of the above that might be of use to some of you. A while ago I saw a post where someone pointed out that you could blacken or white-out parts of your image with the local adjustment brush by just moving the Exposure and Brightness controls to the extremes (left for black, right for white). Today I needed a black arrow to point to a white blob (Snowy Owl) about a mile and a half from my 600mm lens and realized if I set my local area adjustment brust as follows it would do what I wanted. I increased my flow to 100%, my feathering to 0, adjusted the size to small, set my Exposure to -4.00 and Brightness to -200 and started writing a nice black line. With a little practice it came out ok. If I moved the Exposure and Brightness all the way to the right, I got a nice white line. If I reduced exposure and brightness by half and chose a color, I could write or draw in color. After using LR for 6 years or so, it's nice to find this capability.
