Is photo HDR and TV HDR the same thing? speaks to Atlona Training Director Ken Eagle about High Dynamic Range or 'HDR' technology is the latest improved display technology being applied to both photo and TV display, delivering brighter, more colour and more contrasting high performance images.

Is Photo HDR and TV HDR the same thing?

We use the same name for two different things. Photo HDR and TV HDR are NOT the same.

TV HDR is exciting; it’s a different way of displaying video content with more luminance, more colour and contrast. It takes both the display and the content to make that happen. With HDR you have to have content that is encoded in HDR, filmed that way and you have to have metadata that does along – it’s layered on top of the HDR video then you also have to have a display that is HDR capable. HDR capable meaning: it has to have a peak brightness of a minimum of a thousand nits, it has to have enhanced contrast and a wide colour gamut. Then the display reads the metadata that comes along on that HDR video stream and that display then knows how to display each one of those pixels on that screen to make the HDR content.

Where as Photo HDR is a different process photo HDR is using two or more independent photos and merging them together and taking qualities out of each one to create one finished product.

Is there a single standard for HDR?

There are a number of different standards out there and the issue is they are all independent and not compatible with each other. free audio visual training channelGot a question for the HowToAV team?.. provides a whole host of tips, tricks and technology know-how for the professional and residential AV sectors.
