i've been taking more and more shots and have realised that the reason my landscape shots are not as sharp as i want is because of the disturbances in the air...

i notice little waves in the air (not sure if thats the correct term to descibe it) kinda like how the ground looks like on a HOT HOT day, u see like disturbances above the ground... the kinda thing that causes mirages u noe?

i noe my cam is ok, because the closer the image is to me, the less the effect of the air disturbances, and the sharper it is...

anyway, how do i minimise the effect of this disturbance?

i've tried increasing shutter speed and opening up the aperture,
but i think that does more harm than anything...

i've tried half and half (f4, and reasonably fast shutter speed) still not good enuff...

Any comments?

Doubtful that you can do anything about the heat shimmers on the camera. The only thing I can think of is do some post processing to correct for the shimmers. Try taking photos when its cooler? Evening or morning?

Is there any snow? IIRC, sun rays hitting snow and reflecting it back can also give you these shimmers.
