Cameras these days are really amazing devices, whenever a new one gets launched it seems to be filled with more and more wonderful stuff to attract you into detaching with your cash. Surely many of these characteristics can be pretty useful in some situation but for majority of the part a good size of functions will be used occasionally or rarely you can say. This is very true in case of landscape photographer. Strong build, a decent viewfinder, good glass, a dependable light meter and the capacity to modify the shutter speed and aperture individually is all it has to do. The question of pixel count or resolution really comes down to what it is that you will be doing with your pictures, and if you never print bigger than an A4 size, a 6MP DSLR will do the work. 12 MP appears to be good amount for the most of people but even the cameras of lower end are now providing more resolution than this, good if you want big prints or to crop your photos aggressively, but many of us just won’t use the entire resolution of our cameras.
So, your camera will feature many modes of exposure, aperture priority, auto, manual, shutter priority, program and additionally there will be a choice of scene modes to select from. Aperture priority is good in case you have to work quickly, you get to select the aperture and in this manner the depth of field, and the camera chooses a perfect shutter speed to get a wonderful exposure, or at least what it looks to be a well exposure.
What is the purpose of using manual mode?
First of all, it is not to influence your friends or to figure out that you are a proper photographer somehow as you don’t use automatic modes meant for beginners (actually there is nothing like that). There are many people who seem to be captivated with having the most recent gear and how they are apprehended rather than affection of capturing the image.
