HDR? the HDR rules ( photography)

The begining..
by doing some exp. I can undestrood few rules , that ARE important
becouse there is no better aplication than U- a photographer - that can make it look rlly awsome ;)
U have to remmember that each tone on picture need to be registered in camera, so..
- do as many exposures that u can even do, It will depend on enviroment - contrast, so if u are lazy u can do proper HDR from even 3 pictures when its cloudy or rainy and the scene is not black and white contrasted but grey ;)  It will also look natural,, but the most expression will give a highly contrasted scene, Sooooo U need to take a lot of exposures each one to each step (level) of light .
- How to make it happen? (this leveling) , Well if Ur memory is working just fine u can store times of exposure in ur head, but safely would be using some paper.. lets say that it is a shiny end of day at seaside and sun is reflecting beautifully in water...so
- set a camera on some solid tripod(add some weight on bottom so it will not even move..)then set light measure system to spot metering.. then set aperture that u wonna to use, its landscape so i reccomend to use middle state, so if I have 2.8-22aperture i will choose 11 now switch Ur camera to M and  remmember the scene - where it start and end, so what is it including : )  for example maybe there will be objects like : sun, water,waterReflexions,bridge,sand,dark forest,little house,sky. Now u have to be fast - becouse soon it would be darker and darker, quick do measurements of each part of ur scene - using built in lightMeasureSystem and write down(or remmember) all the times uhave got- to do this I am pointing camera centered at object and pressing the button to middle way,and then change value of Time so the light meter would be in right (center position) U can also use alternative method using Av mode set aperture and just pointing with that half pressed button - and write down measurements..
If u are REALLY Lazy U can write down just the brightnest and darkest objects on scene and then cut time line to more or less 10 parts(but i reccomend more if u are using this method)
If U did choosen previous methods U have to just center the scene as U remmember from begining and take a shots inserting the times that u had written. Remmber to not move or shake camera, try to carefully input corrects. If u did that damn good, U can expet AWSOME results. Becouse everything that was important for U in this picture, will be visible same as other objects.
In the end, I can show U why it is important to have a LOT of pictures taken(for better HDR)
Simple home test :

If U will took all of frames as I said, I am sure there is no diffrence in using each software, the simplest one would be just fine.

Ps. If U are doing more than few images, it is reccomended to use JPG file format instead of RAW becouse U will get better and quicker results ; )
