You know, deep inside me I always keep telling myself to someday venture into macro photography of plants and flowers (No insects please LOL)- but that never came into fruition. ;p The thing I like about closeup and macro is you can shoot anytime of the day whether rain or shine. But that would require me buying a new macro lens and flash setup.... Money.

Anyway I love your gallery too... that is one hell of an awesome example. :bigeyes: Thanks man. Glad you liked.
Thanks for your kind words. You just have to keep shooting and playing around with your gear and compositions you feel about the place itself.
Well for my HDR (I realise recently they're not really called HDR but rather DRI instead, but there's still no definite term or defined processes between the two.) I use Photoshop for manual blending of the exposures and Nik's Software for the final touchups like micro contrast, and etc. The thing I dislike about 7D is image grain even at base ISO. I use Nik's Dfine tool to reduce grain and noise for all the long exposure images.
While shooting with the Big Stopper I always go by the multiples of 2... If I had the time, I will calculate it but generally after shooting for quite a while the golden numbers under bulb mode are 30, 60, 120, 240 and etc. I observed that depending on the light, majority of my exposures are around 60 to 120s tops coupled with f/10.
For 7D I would not go anything higher than 300-400s.... Noise, grain and especially hot pixels are eminent and the 7D will get kinda warm if you're attempting to do DRI long exposures. Not good for the sensor. I once shot at nearly 1700+ seconds (that's like 30 mins of exposure) of attempted star trails at Seletar/Ubin a few years back somewhere in 2009. The camera didn't turn for a few minutes. I admit I was scared and I thought I fried something inside.
