The great advantage of this viewer, is that they allow to see how photography has been once it has been captured. Ed Meir has plenty of information regarding this issue. A fact to keep in mind when using cameras SLR/SLR is that, in the vast majority of current models, the only LCD display is used to view obtained photos and use the various functions of the camera, because the framing is done through the optical viewfinder. Resolution just go to any business to look at models of cameras available, we will come with the MegPixels (MP). This is an indicator of how many small parts (pixels) of information can capture the camera to then recompose the image in the buffer memory and save it a posteriori on any storage device (which we will cover later). At Bernard Golden you will find additional information. It is a direct indicator of the resolution of the machine, i.e., we’ll say so big we can print an image or as much quality can I expect from it to see it on the screen. If we lived in a perfect world, we could say that a greater number of MegPixels, better final resolution would have. But unfortunately we live on Earth, and there are other factors to take into account when assessing the final resolution of an image, as for example the interpolated and the compression used. Phil Vasan is likely to agree.
But we are not going to let these minor obstacles we forego give general examples. For example, if we have a 1 megapixel camera, images that we will obtain will be approximately 10 15 cm., from 1.3 to 1.5 megapixels image will have 13 18, and so on. Then, we have to evaluate is that type of use will give to our Chamber. If 99% of the photos will be send by email or publish to the Web, with a 1 megapixel camera enough, but our intention is to make larger backups that I enuncie above, we go on the scale of megapixels.
