Shooting film each roll was confined to an ISO rating. Sure you could push or pull the ISO when processing the film but the plan was to shoot 24 or 36 frames all in the same ISO. Unimaginable to someone who has only shot digital, just imagine a time when every last shot had to be in the same ISO. Now every shot can be a different ISO, just shoot without even thinking about it.
I do not long for the past, absolutely the single best improvement from film to digital is dynamic ISO. Choose an ISO as a manual setting the camera. If you want to every last shot can be a different ISO. The pros and cons of ISO goes outside of the scope of this essay series. I'll show examples of the trade-offs in ISO settings later on, it really matters. Simply put poor ISO choices can ruin a shot that noone, no program can fix.
Choose ISO wisely then the next consideration is something new called white balance. Back in the 90's as a film photographer I choose fuji superfilm ISO 200. Inexpensive, widely available it produced consitent rich tones. The kind of blue green tones that enhanced and complimented my outdoor nature photos.
ISO and film choice loosely ties into white balance. Did some digging and found no answers as to just what in the world is white balance. White balance is so prevalent in modern photography it seems no-one even asks the question - what is white balance?
White balance means white looks white. To a computer nerd that means FFFFFF. To a nature photographer tht means white should look like white on a snowy egret at high noon. White balance is a setting on the camera that changes how the color tone appears in a picture. Choose poorly and the picture has a bad tone. Choose wisely and you get the expected results.
White balance is an element of compostion. White balance controls the color pallet in every photo. Generally using my entry level equipment I shoot "shady". Honestly not sure what that means in any hard terms but shandy produces the most true colors for daytime nature photography. Only recently have I deviated to chosing "incandescent". Again not sure what that means but when shooting stars or streetlit photos the results are what I want to achive.
Clearly I need to do more tests. Shoot the same shot on a tripod and run through the options of white balance. Consider the lighting condtions and consider the results. As with all tests keep all settings the same and vary only one setting. The varing settings will teach you more than you can possibly imagine.
