If you don't mind me asking, what camera/lens are you using?
I used the Nikon D800....it's kind of 'overkill' for just posting images on the internet but it has good dynamic range and good at recovering detail in dark shadows when I underexpose to retain highlights like bright clouds. But it weighs too much. I would be happy with the D610 or D750. I used a Sigma fisheye lens....gives 180* perspective with varying degrees of distortion but most can be corrected with software.
I also use a 9 year old 12 MP Nikon D90 and happy with that camera except it has poor shadow recovery and noise creeps in a iso 800.
