    Why ETTR May Be More Important Than Ever

    As Andrew says, I think it’s important to remember that if you are using RAW the histogram and blinkies will not be accurate. There is something else though. You may think that Camera Raw will tell you what highlight limit you have. I am not an expert so Andrew might like to confirm this, but I believe that Lightroom and Camera Raw use a method of recovering blown highlights that is clever but risky. Usually one channel saturates before the others. Camera Raw generates what it thinks is the correct value for the blown channel based on the other two channels and nearby values. It might give you a stop extra headroom but it isn’t infallible. Sometimes you will get some strange results. I have Rawdigger which reveals that, for my Fuji X-T3, there is only about half a stop more at the highlight end than the histogram indicates, although that will vary according to the jpeg settings, which are many and varied for that camera.

    In the UK you do not have to have a persons permission to take their photograph as long as they are in a public place. If you want to take a portrait then, of course, you would engage with that person and ask permission.

    Re: New computer – how to get Silver EFEX to work in Photoshop?

    Have you got an old version of Silver Efex? It was taken over by Google, then again by DXO who sell it as a collection with the other NIK utilities. I cannot be certain but if you have the old standalone version I suspect that it may not be compatible with PS6 and Windows 10 or the latest mac os.

    Good advice. Can I just correct one item though. It is not possible for a memory card to become fragmented. Fragmentation is something that happens to hard drives only. However, if you want to erase everything on a card you have to format it. Always format in the camera and not in a PC or Mac. That is because the structure of the format may be different. There are often folders created for video for example.
