    New page about light metering with the Leica M9 by Overgaard

    Just added a new page about light metering with the Leica M9 which quite a few have been asking about for a long time. So here it is.

    leica.overgaard.dk - Thorsten Overgaard's Leica Pages - Leica M9 Digital Rangefinder Camera - Page 17: "Light metering with the Leica M9 and Leica M9-P and Leica M Monochrom"


    Enjoy!

    Excellent Thorsten. I'd lost the link to your site and this is very timely.

    I found it interesting and informative. I'll be paying closer attention to where the meter operates, as soon as my M9 gets back from its vacation at Leica New Jersey.

    Re: New page about light metering with the Leica M9 by Overgaard

    "The lightmeter measures an area of 1/3 of the sensor.
    It is not 1/3 of the full viewfinder...but 1/3 of the focal length used;"

    Thanks Thorsten, I believe your statement above is by far the most important and also most misunderstood aspect of the M9's meter. The difference between the wide area the meter measures with a 21mm lens mounted as opposed to the spot measured with a 90mm lens attached is dramatic and must be visualized in order to obtain proper meter readings.

    The large middlegrey card you see in the pictures is still widely available. Partly because the larger stores used to have them, partly because some of them think it is the white balance card

    I've seen them in Tokyo, SF, B&H in New York and many other places. Especially where they tend to stock studio equipment (light, reflectors, backgrounds) there is a good chance getting one.

    Speaking of it, B&H has several ones, this is the Kodak set http://www.bhphotovideo.com/c/produc...ray_Cards.html

    I have already a large gray card Kodak + a Lastolite + a colorchecker passport, but I am looking for a small one like the whibal to keep always in the pocket

    Excellent article and great example of shots! Lighting is everything, and your B&W shots in particular demonstrate, just how important it is. I feel many of us, are looking for the "holy grail" with the M-M, but it is there already with M9

    I think this can be true of any reasonable digital camera if you are careful with exposure and PP.

    Interesting article. I've set it aside to read thoroughly.

    I prefer the X-Rite ColorChecker Gray Scale Card or Photovision 14" Pocket One Shot Digital Target (links are to the B&H Photo site) over a gray card as it provides much more information:

    - fill the frame with the card
    - make exposure
    - check histogram with review :: you can see the card's black, gray and white points in the exposure curve clearly and bias the exposure one way or another.


    capture of Photovision target
    Leica M9 - manual exposure (EV compensation setting not relevant)
    review magnified until target fills screen

    The M9 has the nice feature that when you review an image and magnify it to check sharpness, the histogram display with the Info button renders the histogram for the section of the image you are looking at specifically. This allows for fine tuning your exposure settings very nicely and works great with a gray or tri-tone card like this.

    Perhaps this might work?

    Ah, ok. Well, if it's portability you're after, the Photovision card shrinks down to about a 6" circle for carrying and storage when you collapse it. Of course, if you just want a small card, those Opcards look to be the ticket.

    I think there was another tri-tone and gray card gizmo out there, something like a cube, but I cannot recall the name precisely.

    This is the WhiBal card that I use the most. Fits as a credit card.

    WhiBal - LensAlign

    I also have the X-Rite which is too bulky (the Passport with all the colors too)

    Re: New page about light metering with the Leica M9 by Overgaard

    I would not use the Kodak grey card for any type of White Balance it was not designed for that but really only metering. For white balance the passport is a better tool or a card designed for WB, the Kodak grey card from memory has a yellow bias.
    Photography is all about experimentation and without it you will never learn art.

    but it is really strange that one cannot find a small plastic card for WB and light metering, neutral and 18%

    I've heard of the WhiBal card ... small, balanced to be neutral for both gray card and white balance uses.

    WhiBal - LensAlign

    He makes it in four sizes ... credit card to full size.

    There's also the DGK cards (B&H link):

    Yes, that would actually fix all confusion. Then you can use it for both WB and light metering.

    I'm taking a note

    Thanks Thorsten. I enjoyed reading and learned a lot from reading your article.

    I was wondering if anyone has any experience with and can recommend a less expensive alternative to ExpoDisc.

    Thanks for the article.

    Very informative and have now bookmarked the page for future reference for light metering and the rest of the contents on your site!

    Search on the B&H site for "gray target" ... there are several diffusers that you use like you do an ExpoDisk. Whether they're as good or not I don't know since I've never used any of them.
