In addition to the above techniques don’t forget the essentials:
1. Use a solid tripod
Ever notice that both snipers and photographers learn to hold their breath when taking a shot? Even the humble heart beat can cause that shot to be missed. This is why a tripod needs to be used, not only to stabilize the shot but to reduce any sort of shake. Crisp, clean, blur free photos will be your reward.
There is no substitute for a decent tripod.
2. Know your subject
This revolves around what you’re focusing on. If its the rock in front of you then make sure you’re using the correct aperture to have that rock super sharp. If its the sand dune leading from your feet into the horizon then the same again, be aware of this. Focus on your subject with intention and purpose.
3. Use Mirror Lockup
This is why I like using Mirrorless cameras instead of DSLRs. There’s no mirror movement that will cause vibrations or introduce image blur. However if you have a DSLR system, there will be a setting on most to lock up your mirror. Usually it’ll be by the letters “Mup” or something similar.
Use it as its a landscape photographers friend.
4. Take off Extra Filters
This one is really just for the OCD pixel peepers at heart. There’s theory out there that removing those extra pieces of glass you place in front of the lens may help with picture sharpness. I’m no scientist and I’m not sure about how accurate this is but its a no brainer that if you place a cheap, low quality filter in front of your lens, you’ll lose some optical quality. How much may vary depending on the filter quality, I’ve certainly noticed it!
