Modern cameras come with a huge variety of customizable settings, and it is well worth taking the time to go through yours and set it up to ensure you have the best chances of coming home with the shots you want. This excellent video tutorial discusses 16 settings landscape photographers should consider changing from their defaults to get the best possible images.
Coming to you from Mark Denney, this great video tutorial details 16 camera settings landscape photographer should consider changing. By far, for me, the most fundamental setting I had to change was my shutter mode, namely to a two-second timer. Because we are highly concerned with camera stabilization in landscape photography and often use long exposures, keeping the camera as motionless as possible is crucial. This means not having your hand on the camera when you press the shutter, which is what using the timer is for. Other photographers often use a remote trigger, but I have always found the timer to be plenty for my purposes. Check out the video above for the full rundown from Denney.
