@Joanna Coming from a film background and squeezing the same workflow to digital photography is something I used to react on heftily. These days I don’t care anymore, but I have to add some points to this discussion. Sensors and films are so different from each other that your statement to me sounds like “I’m coming from a slide rule background, where are the slides on this bloody screen?” or “my lathe has hand wheels, I don 't need all this buttons of a cnc-machine, I just use the feed wheel as I used to do”. It’s not about old = bad and new = cool, better. It’s just different. And for the guys preferring an optical viewfinder: Apparently you learnt to live with the shortcomings of a concept developed in an era when there simply were no alternatives, or when a matte screen of 4×5" cost already a lot, not to mention pentaprisms (in this size you’d need a mule to transport a camera), so you have to get used of upside down finder images which also are right side = left side and vice versa. This way of visualizing your photo is not easy to learn and it’s certainly not the way, humans “see” their world. But it’s a way you/we were forced to learn as there were no other ways.
It’s great you still enjoy this technique since it took long to learn it and it would be a misconception to say “but digital is faster (or whatever you like to fill in for more convenient)”. The only faster thing is filling a memory card faster than you could load a film magazine, but it’s very questionable that any of the faster files would later be seen as an image worth looking at. If it (film) gives you all freedom you need to create your images: fantastic. There are just a couple of subjects coming into my mind when a field camera would not catch a single image. Nonetheless, taking your time for an image always pays up at the end. It just not necessarily “only possible” when using film. And there is no rule saying “only with a proper white balance” when it comes to “what makes a picture great image?”. Honestly, back in the days of film there were no two colour film types (negative or positive) showing the same colour characteristics, no matter how often “daylight type” was printed on their boxes. Even the same film type had differences between different batches, and batches wer involved in everything: film carrier, emulsion, developer, temperature, water quality, age of chemicals, type of developing machines… hell, there is close to no single truth in film. As there’s also no single truths in any sensor.
An image with good colours isn’t necessarily taken with “the precise white balance of 5421K” or whatever value you think you set your camera to. Measuring it and get the real number in K is a different story. And comparing your memory in your brains with the end-result is another different story. Therefore it’s pointless to give °K recommendations, too many variables influence the end result. Use the ones you’re happy with. And adjust it in post, if you feel it should show more green tint.
The one thing I learnt in photography: recipes are a good thing, but important is the taste of the soup when you eat it. And knowing what ingredients do is far better than trying to create repeatable, exact same taste each time I cook it. Or only use wood stirring spoons, cast iron pans and cooking with a gas cooker.
