Viewfinder Grid Lines..

Many of you know you can set the camera to have various grid lines on the screen from the system menu.

I am curious if anyone knows how its done? I dont mean how its done in the menu but how is it physically done. Cos ,you can change the focus screen and the grid lines will still be there..

Furthermore.. if its some kind of LCD thing then wouldn't it be cool to have it instead of fixed grid lines maybe Nikon can provide pixels where we can program the grids ourselves !  I don't think we will need more than 340 X 200 pixels to play with :-)

    Yes, I think it is done using liquid crystals. Adding a matrix would be kind of cool but would probably add to the expense of the camera. 

    I'm still wanting to get a Katz eye focusing screen for my D7000 sometime, and they can rule all kinds of crop guides and grids on it for you. I think I would probably put the 8:10 guide on it. The 16:9 would also be handy, but live view already has some guides for that.
    CC is welcome. DC is also welcome when I deserve it.

    It would be nice if Nikon added more things to the screen, but without an electronic viewfinder you loose some light with every item to you display.
    If I take a good photo it's not my camera's fault.

    I had a question about the viewfinder of my D90 some time ago and Nikon did tell me that the lines are LCD, so it could be possible to give you the ability to cycle round various designs - including square - on one of the programmable buttons.  Nice idea Hearty.

    I was just thinking about that the other day...  I always have my grids on but was unaware it was LCD...  Makes sense tho. If you are dumb enough to take apart a DSLR lcd (I've done it successfully) you will find that the actual image generating segment is clear glass on both sides.

    I think they also use it to show you your crop area on a Fx camera in Dx mode. (I talked with somebody who was using an 18-55mm on a D800, only time I've seen the mode in action...)


    I like that idea of programming what goes on the grid Heartyfisher...

    That's actually an interesting comment kyosinikon, because there are of course TWO very different types of grids in play (at least on a FF body). There are the grid lines that you can switch on and off in the CSM menu, and which glow Red like the focus point/s, but there are also the framing (crop aspect?) bars, that appear as permanently Greyed out sections of the viewfinder, when you shoot in anything other than FF. I presume these are also LCD? I for one always have my grid lines active. I find they help me to remember my "thirds" and with my horizontals! :-)

    Yes, that is also the LCD. That is why the viewfinder goes dark if you have no battery in any Nikon DSLR.

    PB_PM is completely right!  That answers that question. I occasionally pull a "dead" body off my shelf and the screen is grey unlike my analog SLR's....  I do love that grid feature. What I am wondering is why they don't allow for more options. It would be cool to load the fibonacci spiral, even better a decent virtual horizon, or even better a sharpness feature like the a99 has...
