This is the original of my first challenge submission. I am using it as the one I was pleased with the results because, even over a year later, I still remember clearly how startled I was at how well it was exposed.

I had heard that 'real' photographers exposed with a grey card, but at the time didn't know why. I decided to try it, but I didn't have a grey card so I improvised. I used a grey microfiber cloth I use to clean my glasses. It still amazes me the difference exposing on something grey makes.

Unfortunately the grey cloth I used is about a stop lighter than neutral grey - so the image is underexposed by that much. This would be acceptable if it wasn't for the loss of detail in the black top my wife had on.

But because I had intended to duotone (sepia actually) from the beginning I wasn't too worried abou that (or the clashing colors between red hair and blue background. :)

awwwhhh the sample paper to carry everywhere.... The first lesson in our photography meetup group this year was about setting the white balance and the exposure in your camera by taking a photo of a white card, black card, gray card, or the Kodak card that has all the colors I believe it would be 256 colors on that card. To be exact O had to look it up.. its the Kodak Polychrome, Colorflow, custom color card..(Gives you a true colors square for all the colors and a chart with all the values of the colors.) Mr. Parks (majoring in color science) used it during his demonstration...It was indeed the best 2 hours of non stop talk about color science, color management, and white balance....At the end when it was time for us all to go home...everyone left with headaches, I'll tell you my head was splitting open and others were complaining too..There is more than 2 hours of info he went through but after I started reading again about it all it started sinking.. Here you have the best color range for sure.. You can match up the colors in the light of your subject in a photo program when you take the photo of the card too. I have tried.. but my editing skills arent the greatest and I find myself skipping out on taking a pic of these 3 imporntant elements..white, black, and gray...You more than likely know about all of this, I just thought I share for others and to see how much I remember..Here is a site that I just found that really goes in debt with the Color balance and it says that a sample color card from wall paint that you can find in home depot, walmart...would do...its rather intersting.. //www.microscopyu.com/articles/digitalimaging/colorbalance.html

It looks really good to me. I'm going to have to try exposing with a grey card. It's pretty rare for me to get such good exposure right out of the camera.

SOOTC? I'm not familiar with that one.

/edit: nevermind, I searched for it.

"Straight Out Of The Camera" :)

I think this is great exposure. I see no problems.

David, firstly thanks for posting your SOOTC original. This is what we need if we are going to work together to achieve predictably good exposure. Secondly I like the photo just as it is (and I have to say I love a quantitative girl!)

I agree with your analysis of the exposure. One of the things I like about this is that it has variety of exposure and good intense and well saturated colors. This will make it an intrinsicly more interesting photo. You can see it in the histogram with multiple spikes. And you can see the exposure bias (left shift) due to your use of a a micro-fibre gray card.

A fine job and a good model of good exposure.
