I've been trying to improve upon taking better sunrise shots. This one was taken 1/50sec ISO 100 44mm with a inexpensive UV filter, mirror down and camera resting on something solid. I used LR to add a little more exposure to the bottom third and less on the top third. I suspect there are some basic things that could be done without the purchase of filters to improve the photo. Although if there is a filter that would significantly improve upon things that would be also helpful to know. Thanks in advance for any suggestions.
