The quality of my pictures are not that good. I have tried HDR and I get better results from modifying RAW files. Not that my results are that good even with the RAW files. My pictures are to dark if unmodified. When modified they are grainy. Obviously I like to see through the windows even if I can't get there at the right time of day. I currently use a Canon XTI with a Canon 10-22 on a decent Manfrotto tripod. I do not use a flash. I am looking at the Canon 580ex II but at over $400 I question if my results will be any better. I think I may get a better DOF if I increase my F stop but to what. I shoot at f/5.6 and an ISO of 100 and the light is metered. If I buy a flash I feel like one will not be enough because some of the units I take pictures of have fairly large and high areas. I want something that will lay-down an even layer of light for 16mm (the effective FOV for the 10-22) I am not looking for architectural quality photos but I am looking for good quality. I would like a recommendation on a light kit for an un-reasonable price of less than $500. I have tried every HDR program on the market so that is not an option, my results are OK but it takes far to long in processing time. Camera setting recommendations are very welcome. I talk to much so I will stop but below you can see some of my pictures This is my website portfolio. http://www.ktoris.com/photography/portfolio.php Thanks for any comments.
