Terms – white balance

White balance is an interesting setting for digital cameras. When shooting portraits the photographer is sure to want the colors true. This is a setting of “custom” white balance.

Gary Fong has posted a video to YouTube giving visual instruction of how to set you Canon 5D custom white balance. Custom white balance Canon SLR settings are not complicated to adjust.

If you do not have the tools for setting your white balance that Gary does, a white card with true black and 30% gray sections are perfect for the same use.

There is only one difference to remember as you set the white balance…instead of letting the light come through the dome as Gary demonstrated, simply hold the card next to your subject and take a picture of the white section (making sure to have your memory storage in your camera whether internal or CF or SD).

I mention the memory card because some photographers will automatically transfer the images to a computer or hard disk and not in their camera. When this is done the camera cannot reference the photo for color imbalances.

Enjoy, and keep the colors true!

Camera Troubles – Part 4

With this basic knowledge we have built on the human Eye and how the camera lens was designed from the model of the Eye, I would like to venture into some observations of human vision.

Again please take note of my disclaimer from Camera Troubles, “I am not an Optometrist”, so I am not attempting to prove anything for or against medical science but observing our ability and capability.

We have some magnificent capabilities to see detail in deep shadows while focused on well-lit objects. It is in fact this ability that I find most fascinating, because I have tried to  figure out whether I had looked into the shadows subconsciously noting the detail or if I am seeing that wide a spectrum of detail. In either case, the ability to see the wide range of detail in light or shade is a characteristic that I have not yet found innate within a camera, but I find it most common in creatively thinking people.

There are some ways to achieve the look of detail in shadow while focusing on the lit focal point. Before going to the topic of how the camera see a scene, we would do well to better understand what and how we see.

I have a hard time discerning the varying degrees of light and how well the area is lit where I am shooting. This I know from experience and so now I take some test pictures before getting into the heat of the photo shoot. This tells me some amazing things about my Eye sight. The Iris opening so wide that I do not notice the slight shadows between light fixtures and my Brain filling-in details of the wall paneling. We have an awesome device in our Brain to automatically fill-in such detail! Thank God for giving us such magnificence to be used and shared!

Now we have not discussed the process in-depth of taking the photo after exposure from the Sensor to Storage. So in the next posts in this series, I plan to explore “The Data Transfer” and “What the camera sees of what I do.”
