Hello guys, i just get my sekonic 758 dr and i want to calibrate for use with my nikon d800, never i used a lightmeter , i have a few question and before all am sorry for my bad english will try to be clear.
1- i saw several types of card for use with sekoni 758, all do the same at the end?
2- i am interested for now in get a profile for the dinamic range of my camera , what type of card i need for do it? (hoping the cheap way : )
3- worth buy those expensive cards?
4- i saw a cards like this:
how the scale of greys is related to colors tones? what means this? it does mean if i doesn't take the pic with the proper range of grey tones i can lost some colors?
5- the calibration of my nikon for dinamic range can be done only with a grey card? thanks very much guys.
