I found this of interest. Whilst it has a US focus, it sets out some useful principles to consider. From David Coen of PikWizard:

PikWizard’s guide How Photography Copyright Laws Affect What You Share Online explores everything you need to know about copyright infringement. It covers what copyright infringement is and how copyright infringement works.

It can be hard to tell if you’ve used copyrighted materials without permission before. There are a few things you need to remember: photography copyright is automatic, and you don’t need to use the copyright symbol to protect your photography portfolio.

If you are unsure whether to use someone else’s photography, it’s always best to ask.

This guide also covers how copyright is created, the benefits of registering copyright photography and protecting your work online.

There is also an infographic on the post which has some helpful reminders.


DNG files and White Balance

Following a friendly debate on Facebook about the impact of White Balance camera settings on Leica’s DNG files, I did a very quick ‘real world’ test. Normally, the White balance setting is reckoned not to alter  RAW capture, although all cameras process the RAW date to create usually proprietary files – e.g. Nikon creates NEFs. Leica however uses Adobe’s DNG file format.

I took a serious of identical shots in rapid succession using the Leica Q2. That way the ambient lighting was identical. I changed the White Balance on the camera between shots – all other settings are the same (F8 and 200 ISO). The subsequent JPG conversion for use was identical.

Here are the results. Click on the image to see it larger.

Auto White Balance

Daylight White Balance

Cloudy White Balance

Shadow White Balance

Tungsten White Balance.

You can see that Daylight is cooler than Auto. Daylight is balanced for sunshine, it seems, and so it slightly ‘offsets’ the yellow light of the sun. Cloudy and Shadow are very similar to Auto, although Shadow is a fraction warmer. It was cloudy conditions at the time of shooting, so no surprise. Tungsten is off the charts of course as it should not be used outside. I include it just to show that the DNGs are actually processed in camera.

And here is a strip which is easier to see the differences.

My conclusion? Frankly, I will continue to use Auto White Balance as any differences are easily handled in post. Maybe I am lazy, as I know that choosing a fixed White Balance for a series might be a sensible move for consistency. But, hey ho …
