Seeing as this is photography for geeks: Colour temperature is exactly that, a temperature.

Things glow when hot, with the colour of the light depending on the temperature and the material. When you say "a colour temperature of 6200 K" it means the light is the same colour as that emitted by an ideal black body at that temperature. It's no coincidence we perceive colour temperatures around the high 5k to low 6k as white, because the surface of the sun is around 5800 K.

Just sharing: If you want to learn photography, buy yourself a film camera and read those two books. Ansel Adams: The Camera https://amzn.to/3gMyCa5 The Negative https://amzn.to/3U88fsN The rest is just practice.:)

I think for learning photography today, using a film camera will very likely wasteful, unless you are pursuing a photography degree, for example.

Get a digital camera. Instant feedback and histogram are very useful for judging your exposures. Once you are comfortable with that, you may pick a film camera.

If anyone wants to move beyond using the "auto" setting on their camera (or phone), I would recommend the book Understanding Exposure by Bryan Peterson, the first edition of which was published in 1990: * https://www.goodreads.com/book/show/142239.Understanding_Exp... The principles involved haven't changed much in the intervening decades; the current fourth edition was publish in 2016. If all you have is a phone you…

Aperture Size, Shutter Speed and ISO. Just understand what they are. And their units. Actually see pictures varying one and keeping others constant to get a hang of things. Then go backwards, check professional pictures and guess the values. Professional photography forums all photos have these values published . Night/Day photography, moving/still and background focus are the only 3 skills you need as an amateur pho…

+1 for printing, which are a rare habit on social media era.

Virtually any image looks great on FB/Instagram/etc, but once you printed it big, you'll notice how good or bad actually it is.

The things I’m drawn to in life is where art meets science. In hindsight, so much of the secret is knowing how to avoid failure. Baking bread? Build the intuition over time and you’ll realize baking is forgiving so long as you don’t do these “5 bad things.” Gardening/farming? Yeah, there’s a big list of bad things. Brewing beer? Another list of things to avoid. The basic rules (rooted in science) are like guardrails…

Using a film camera will force you to take the picture with your mind first. You will understand exposure and light in a fundamental way.

You always can use your phone, computational photography will give you the best result, algorithmically speaking.:)

> The principles involved haven't changed much in the intervening decades. My problem with many old-time tutors is that they refuse to recognize that photography has gotten a lot easier. We don't need to learn the craft the way they did. For example, you don't need stuff like the "sunny 16" rule of exposure if you have real-time previews in the camera. You use visual feedback, usually with better accuracy. In the sam…

The point of learning Sunny 16 is that once you’ve internalized thinking in full stops, you don’t need visual feedback, which makes you faster, which can make the difference between getting your shot or not and having a happy or angry client.

> Or, you don't need to learn about optical filters (perhaps except for the polarizer) when almost all their functions can be accomplished in software without loss in fidelity.

I still think it’s a good idea to learn what they do, so you know when to use a (digital) BW red filter because you want brighter skin.

Earlier quoted context omitted.

Any specific recommendations?

If you want interchangable lenses look at the X series, XT-3, XT4, XT5 (just released). X100V is sold out to eternity due to popularity. XPro3 is popular too. https://en.wikipedia.org/wiki/Fujifilm_X_series#X_series_chr...

Or an XE-4 if you want a smaller body and keep the interchangeable lenses.
