Pro­duce your sharpest land­scapes with our pro guide from Mark Bauer

suc­cess­ful land­scape pho­tog­ra­phy has al­ways placed a lot of em­pha­sis on de­tail and sharp­ness. how­ever, with the in­tro­duc­tion of mod­ern high-res­o­lu­tion sen­sors, sharp­ness and the tech­niques needed to achieve it have be­come in­creas­ingly im­por­tant.

so what con­trib­utes to­wards im­age sharp­ness? equip­ment ob­vi­ously has a bear­ing on this, start­ing with your choice of cam­era. sen­sor size has an ef­fect, as does sen­sor de­sign – for ex­am­ple, if there is an anti-alias­ing fil­ter in front of the sen­sor, this will cause a de­gree of soft­ness. Lenses also have a sig­nif­i­cant im­pact. it used to be the case that primes were no­tice­ably sharper than zoom lenses, but in re­cent years some ex­cep­tion­ally good zoom lenses have been made avail­able. how­ever, good lenses don’t come cheap – spend­ing a little bit more will usu­ally re­sult in more qual­ity. the good news is that the most use­ful lenses for land­scapes are wide an­gles, which are con­sid­er­ably less ex­pen­sive than tele­pho­tos. More­over, us­ing a suit­able tri­pod and head are as im­por­tant as cam­era and lens choice.

how you con­trol depth of field – via your choice of aper­ture and where you fo­cus – also im­pacts upon the sharp­ness of your images, and choice of aper­ture is also im­por­tant in con­trol­ling op­ti­cal aber­ra­tions such as dif­frac­tion, which can re­sult in soft­ness. to be fully in con­trol of sharp­ness, you will also need to mas­ter more advanced tech­niques, such as fo­cus stack­ing and us­ing tilt-shift lenses.
