Lightroom Classic – Cameras, Profiles and White Balance

This article is not meant to be a “do it this way” style post, more an “Oh! I didn’t fully understand that” … and probably still don’t!! Don’t stop reading though, as there might just be something (like me) you hadn’t grasped, or hadn’t stopped to think too much about it before.

The starting point is that you’re shooting in RAW, if you’re not then a lot of what follows will be academic because you will just have to accept and set in camera the colour profile one of the ones your camera manufacturer provides. [Ref. How to Use Your Camera’s Color Profiles in Lightroom]

... manufacturers started adding color profiles to their cameras. I’m using the term color profile deliberately because every manufacturer has a different name for it. They are listed below:

Canon: Picture Style
Nikon: Picture Control
Fujifilm: Film Simulation Mode
Sony: Creative Style
Pentax: Custom Image
Olympus: Picture Mode

Fujifilm’s approach is interesting because they have named their profiles after genuine film types. As a result, Fuji color profiles are more nuanced and subtle than those made by the other manufacturers. This new approach to color profiles is one of the features that sets Fujifilm cameras apart from the competition.
I will be using the Sony A7rIII as the camera that I refer to when discussing colour profile, but it shouldn’t be too difficult to see how this applies to other cameras, so I will be using the term Creative Style to refer to the in-camera profile you can set.
So you have the option of choosing a Creative Style, but perhaps you should pause and consider whether that’s the best approach. You’re almost certainly going to be post-processing in Lightroom, so perhaps it might be a good idea to start from a base that never changes. So from the choices in the Sony camera – Standard (default), Vivid, Neutral, Portrait, Landscape, Black & White. The default is Standard, but I’ve chosen to use Neutral as I don’t want any in-camera adjustment.

The same logic applies to White Balance. In the Sony you have the choice of Auto WB (default), Daylight, Shade, Cloudy, Incandescent, Flourescent, Flash, and a few more specialist ones. It would seem “obvious” to leave the camera on the default setting as you could be assured that the “best guess algorithm” it adopts would be the best base to start from. But better perhaps to choose a “known” setting such as Daylight (5050K) and to change that in post-processing. [NB not all Daylight White Balances are the same. In Lightroom, Daylight is 5500K – just to confuse everyone.]

Then we turn to Lightroom. At Import you are able to apply Develop presets, and this is your opportunity to change both of the above in-camera settings, or to adopt the camera settings to work from, as the base of your post-processing. This is what I do and I have set the Develop settings on Import to be the Camera settings, ie Neutral and Daylight.

By now you’ve probably begun to think, “does this really matter?”, so we better get down to some specifics. I’m going to use some images taken in Llandaff Cathedral to demonstrate the variety of results you can get. Just to re-iterate, if you’re shooting in RAW you can change these; if JPEG you can’t – they’re baked into the image.

First of all, shots taken with the White Balance set to Daylight (5050K) – my preferred setting as an everyday base.

The differences are subtle, I grant you, but there are differences in the colour casts and if you’re taking shots in different locations, and in different styles, it might be best to have one that you know, you really really know, to have as your base. As I’ve written above I’ve chosen to use Camera Neutral, but I could quite easily have also chosen Adobe Neutral as I’m using the Adobe RGB colour space in my camera, rather than sRGB – the other alternative.

Now let’s look at the same shots when a Lightroom Tungsten White Balance setting of 2850K is applied after Import.

Again the differences within the Tungsten White Balance with the chosen Colour Profile are subtle. What these shots show is how much White Balance (not unexpectedly) will change the image, but I’m satisfied that either of the two Neutral Colour Profiles provide me with a suitable base image to work from, and I can then successfully chose the most appropriate White Balance using the eye dropper in Lightroom to the image to get the best result to then start post-processing work on.

The featured image at the head of this post was created using a Sony Camera Neutral Creative Style, and using Daylight White Balance on capture, subsequently changed to Custom 3950K, and then Auto Basic Settings applied in the Develop module.

How does the Internet work?

[Revised 17th January 2023 and February 22nd 2024]

Now there’s a question. Once upon a time it was a little easier to answer. You connected your computer with a piece of wire to a socket in the wall and beyond the wall was ??

So perhaps it’s never been easy to answer that question. It’s not magic, it’s not fluffy, it’s actually really complicated technology which works in a relatively simple way to make things relatively easy for us to use it. Let’s start with a few videos …

How does the internet work? – This [updated] BBC Bitesize page (produced for children) is a really good starting point to help you understand how the internet works and introduces some of the terminology (ie protocols, packets) that will be useful to you to understand the other videos.

How the Internet Works in 5 Minutes – the internet is not a fuzzy cloud. The internet is in effect a wire (or a fibre-optic cable), actually buried in the ground or carried as wires between posts. Computers connected directly to the internet are called Servers, while the computers you and I use are clients, because they are not connected directly to the internet, but through an Internet Service Provider. Mobile devices away from the home, connect to the internet using radio-waves to connect to cell-towers with increasing capacity being generated by increasing the frequency modulation of the waves (ie 3G, 4G, 5G and even 6G). Mobile devices in the home or in the office, or in public hot-spot spaces, use WiFi to connect to the internet using two frequencies – 2.4GHz and 6GHz. All of these require Routers to shuttle packets of information across the internet, and transmit e-mail, pictures, and web pages. Although this video is a little dated, it really does explain the process of what happens when you connect to the internet …

A more recent video and the ones that are referenced at the end of the video will get you a long way to understanding the technology that makes up the Internet.

How Does the Internet Actually Work? – this discusses how internet traffic can be labelled to ensure that packets of data can arrive at their destination with the minimum amount of disruption [- but it is a biased view in favour of scheduling]. However for an impartial point of view of Net neutrality, you should probably look at this video produced by Vimeo – strong supporters of Net Neutrality …

… and the policy documents from the Internet Society and Electronic Frontier Federation.

Finally a couple of alternative views of the internet. First, Andrew Blum (in a TED Global talk) philosophically examines What is the Internet, really? A journey that started for him when he found out a squirrel had chewed through a cable led to him exploring trans-ocean cables and the very physical nature of the internet – a wire! Then this rather entertaining video …

… takes us from very local internet and cell-phone technology, through an examination of data centres such as the former Western Union office at 60 Hudson in Manhattan, to laying ocean cables and the future with balloons acting as transmitting stations for low-density inhabitation, or remote areas.

You might also be interested in seeing a Google Data Centre, in particular the pieces on security and cooling are interesting. [However, all of this increasing use of the internet comes at a cost to our environment as the advance of Artificial Intelligence and its huge need for energy for increased computing power comes at a cost.]
