My Lumix LX7 has an \u2018high-dynamic range\u2019 feature. Otherwise known by its initials \u2018HDR\u2019, high-dynamic range is a technique for digital imaging that allows greater detail in highlights and shadows by combining several images of the same subject that were exposed at different values.<\/p>\n

The LX7 includes the HDR setting as one of the options in \u2018scene mode\u2019 (SCN on the selection dial). This rapidly exposes a sequence of images and combines them in-camera to produce a single HDR JPG. Obviously you need to hold still when you make the photo.<\/p>\n

Also it helps to photograph a static scene or the result my get a bit weird.<\/p>\n

In this instance, I photographed some flowers on the platform of NI Railway\u2019s station at Whitehead, Co. Antrim (Northern Ireland).<\/p>\n

This is my HDR composite photograph. The camera automatically exposes a burst of images at various exposure settings and combines them in-camera to produce a single image with greater shadow and highlight detail than is normally possible with a single frame.<\/figcaption><\/figure>\n

There are other ways of accomplishing a similar result.<\/p>\n

So I decided to compare the HDR with some manipulated versions of a camera RAW file that I exposed of the same scene. With the RAW images, I\u2019d adjusted the file with Lightroom post processing software, selectively altering contrast, gamma, and colour saturation and colour temperature to make for a more pleasing photograph.<\/p>\n

Specifically I applied a digital graduated neutral density filter, while making global changes to highlights and saturation.<\/p>\n

The output of the RAW is also as a JPG, which I scaled for presentation here.<\/p>\n

\"\"
This view is from a single RAW file exposed with the Lumix LX7 and manipulated digitally to maximize highlight and shadow detail. This is my first of two manipulations.<\/figcaption><\/figure>\n
\"\"
This is a more intensively manipulated file than the image immediately above. Again this image was from a single camera RAW file. This one features slightly darker highlight values.<\/figcaption><\/figure>\n

I made two versions of the RAW interpretation.<\/p>\n

In both sets of images I\u2019ve intentionally focused on the flowers and not the NIR train.<\/p>\n

Which do you prefer?<\/p>\n
