HDR using fusion?

Post by johnp »

I've not yet played around with HDR, but in looking at some Magic Lantern info, I stumbled into
the option of doing HDR using image fusion algorithms such as provided by the "enfuse" software.

Has anyone played with this type of HDR combining?

Thanks!

Photomatix offers fusion as one of two methods it can use to do HDR, the other being tone mapping. Depending on the image one method or the other may produce more pleasing results.

Have you considered adding fusion type functionality for HDR?

Thanks!

A free, portable fusion program that you might explore is "Fusion F.3" at: http://fusion-hdr.com/home
Free version: Fusion F.3 __ Date of updating: January 7, 2016
Fusion F.3 is restricted version produced from Fusion 2.8.8...
Restriction list: only one processing mode in summation operator; only one tone mapping mode in HDR operator; there is no postprocessing tools; there is not batch processing operator; save result image only in jpeg format; there is not 64-bit version, only 32-bit. OS: Windows Portable package: "fusion_free.zip" (8,00MB)
Works with my OSs: Vista 32bit and Win10 64bit... ...expand the zip file to a folder and add a desktop shortcut link to 'Fusion.exe'.

Note that the free version is limited to one fusion mode [SUM] and one tone-mapping preset [HDR].

Example with scene exposures -1ev, 0ev, and +1ev...

P.S. I tend to prefer HDR tone-mapping by SNS-HDR then fusion methods as the results can be more 'dramatic' depending upon the preset one chooses...

I have looked at it a few times, but it's not easy to implement.

Jonathon -

I thought there were some open source fusion implementations???

Also - Thanks for PWP! It's great!

Jonathon -

FYI - enfuse is open source, the following link has some .gz files with the source, I believe.

Hugin, the open source panorama software, apparently automatically determines if a set of input images is an exposure stack for a single or panorama image and can produce HDR type output via enfuse, I think. I've only ever used it for its panorama functions (which are excellent). The 2016 version was just released last week.
