Hi guys, thanks for all the replies. I went for a test shoot last night. So i've decided to try it with Canon's photomerge. lol
I understand the rule of pano, is the exposure has to be constant, the focus as well right? So i shot it in manual, 2 shots side by side, my interval degree is about 15 degrees? Everything came out fine except that the difference in the sky is rather obvious.
Since it was a night pano, the sky is supposed to be dark, however there was a slight difference in the level of darkness for my sky. Any tips?
Back to topic: I think I'll try this Ptgui
