Review Update

Some DxO improvements

DxO Optics Pro has been updated to version 6.5

As well as a whole lot more lens modules, there are changes in the functionality that I thought it worth showing examples of.

We have a full review of DxO 6.2 which covers many more details of the software.

I've long used DxO Optics Pro for some of my images to get the benefits of its very good RAW processing.

Recent versions have drastically improved the handling of noise in images, to the point that if I'm reproducing a print from a few years ago, taken with my Canon 1Ds at high ISO (1000/1250) then I'll seriously consider reprocessing the RAW file (one more reason to keep your RAW files).

Updates -

 What's new

This from DxO: "DxO Optics Pro 6.5 introduces exclusive Single Shot HDR technology for optimised rendering of contrasted scenes. Other new features include improved RAW conversion, Lightroom 3 support, speed enhancement, and increased cameras and lenses support"

DxO have also released a specific HDR plugin for handling multiple images for HDR creation - we'll look at that in its own review.

I'm seriously not a fan of the over the top 'artistic' HDR look that is one of the current fads to pass through photography.

That said, I do use HDR techniques to extend the dynamic range of some images and was interested to see what DxO 6.5 could 'pull out' from some of the rather dark images I've got after avoiding burning out highlights,

Using DxO Optics Pro

I've selected an image from when I had a Canon 7D to test last year - Just after I'd got the camera, I went out to grab some shots before it got dark (EF14 2.8L II lens).

This particular one was underexposed a bit, so as not to burn out the sky colours and detail

There are three 'HDR' presets

First I've set for 'slight' - you can see how some of the DxO lighting settings have gone from auto to manual.

Using presets in DxO is one of its strengths and one I have to admit to neglecting somewhat in my own use of the software.

different HDR processing options

This gives a good feel for how the scene looked.

Remember, there was an extreme range of brightness - I'm looking into the sun.

The artistic version is just moving a bit too far from how the scene looked to me - I did not have huge banks of lights set up to light up the road and those bushes in the left hand side.

Here's a 100% crop at 'Realistic'

Noise reduction seems slightly less prone to lose detail in high ISO shots in V6.5.

As ever, high ISO noise reduction is a matter of taste and subject matter.


The single shot HDR shows just how much information is in those shadows. It can look great, or it can look seriously 'overdone' - your own opinions of this current fashion may well differ from mine :-)

Thanks again - Keith and Karen at Northlight Images

I was impressed - it's already help produce slightly better looking versions of some of my commercial images. I don't see using it a lot, but when it's needed, it's nice to know what it can do.

DxO keeps its place as a valuable option in dealing with some of my RAW files.


Numerous improvements on the already rather good DxO V6.2

Works stand-alone or can be integrated with other software solutions such as Adobe Lightroom.

The software has a lot of functionality, and once you move to advanced modes it can be quite complex, but well worth getting the free demo to see how you like what it does.

Can be purchased in download form.
