Enfuse - new blender
Posted: 21 Dec 2007 at 9:13 GMT

The new blending progam Enfuse has just been announced over on the PanoToolsNG forum and has caused quite a stir. It's for blending exposure bracketed shots together to produce an LDR result directly rather than HDR. It comes from the same stable as Enblend, and is in fact part of the pre-release version 3.1 of Enblend. It was this image that caught everybody's attention - produced by Erik Krause with a straight Enfuse command (no parameter tweaking):
It does look somewhat lacking in contrast, but that can be attended to with some adjustment in Photoshop, according to taste. The original braketed images can be seen in Erik's Contrast Blending tutorial at www.erik-krause.de/blending/
Running Enfuse without parameters displays the following help:
Usage: enfuse [options] -o OUTPUT INPUTS
Common options:
-h Print this help message
-l number Number of levels to use (1 to 29)
-o filename Write output to file
-v Verbose
-w Blend across -180/+180 boundary
--compression=COMP Set compression of the output image.
Valid values for compression are:
For TIFF files: LZW, DEFLATE
For JPEG files: 0-100
Extended options:
-b kilobytes Image cache block size (default=2MiB)
-c Use CIECAM02 to blend colors
-g Associated alpha hack for Gimp (ver. < 2) and
Cinepaint
-f WIDTHxHEIGHT+x0+y0 Manually set the size and position of the
output image.
Useful for cropped and shifted input TIFF
images, such as those produced by Nona.
-m megabytes Use this much memory before going to disk
(default=1GiB)
Fusion options:
--wExposure Weight given to well-exposed pixels.
--wContrast Weight given to high-contrast pixels
(unimplemented).
--wSaturation Weight given to highly-saturated pixels
(unimplemented).
The Fusion options parameters have no effect so far since only
--wExposure is implemented and hence default. -c works only if the
source images contain a color profile.
You can download the currently Windows only version from hugin.panotools.org/testing/enblend/enblend-3.1_w...
As it's pre-release, there may be bugs! Read the NEWS and README files.

Very impressive demonstration!
I have a feeling that the next (or the next after next) release of PTGui will support enfuse some way

Mac users who are shy of command line and compiler coding (like me) can try Enfuse by using Kevin Kratske's XBlend and pointing the blender to enfuse.
You don't get any of the controls of the parameters of course but it is still a very good blender.
Like all of the so called HDR techniques it has its place and may even prove to be the best yet available. Hopefully a Mac programmer will build a GUI front end to take advantage of all of the parameter controls possible.
BTW XBlend is donationware and to date apparently only one person has done that, so shame on us all who use it without paying up. I'm going over to PTMac now to make a retro payment and given the known generosity of subscribers to this forum it would be nice if others did the same. Unfortunately PTMac has been almost completely superseded by PTGUI for Mac and many newcomers will not be aware of the fantastic contribution that Kevin has made to the VR community.

It already does. If you are creative,
And so does PTMac and PTBatch also

Andrey, I'm not a fan of HDR, but that pano looks very good, with no obvious artifacts to draw attention to the blending process. I think enfuse is going to be very popular.

John,
I share similar approach to the HDR: the less noticeable it is - the better. Never was a fan of sci-fi style images with the lead sky and shadows filled by the second sun

Hey irieman,
This is very exciting the possibility of running enfuse on a Mac. Wondering how you did it? I tried following your directions (above) Can you tell me how you point the blender to enfuse with XBlend? The only version of enfuse that I can find is enfuse.exe. Do I need to find a Unix version of Enfuse? Please help??? THANK YOU!

Just set the location in preferences in the usual way - but yes you do need the Unix file. I downloaded it from a link that Hans posted on the Panotools forum - I can't find that immediately but I think that this also works www.rogerroger.org/enblend3-20071230.zip
Oh and if you want a GUI front end go over to PTMac and cross Kevin's palm with silver!!

It was not on the panotools forum but at Kekus
kekus.com/forum/showthread.php?t=1950
And please ask Kevin for the update of X-Blend to use enfuse.
They are also beginning to discuss it at panotools so if he is not fast someone else does it.

I stand corrected - yet another senior moment. 
Do ask Kevin as it would be great to have him involved - and don't forget to make a donation.

Sorry for the cross post from the Kekus forum but I guess this forum gets a lot more traffic.
I've created a nice and simple automator action to run enfuse on OS 10.5. Please note it does not and never will work on 10.4 due to the massive 10.5 automator update.
All the instructions you need are on the 360Precision website at:
www.360precision.com/360/rd/enfuse/
You can download the latest working enfuse app and actions you need from:
www.360precision.com/360/enfuse/enfuse.zip
The interface is quite limited at the moment due to that lack of documentation for tying command line apps into automator. The other limitations are:
1. You must use tiff files with the extension .tiff, this is hardcoded and I'm not sure this will change anytime soon.
2. The output directory is hard code to /Documents/enfuse/output/ again if I can work out how to set it I will, if not I might look at building a Cocoa interface instead.
3. Even though all the sliders seem to be set at zero the actual default values are in the brackets next to the control names. Again I think this is a limitation of Automater/Command line. The sliders do work and will send the correct values to enfuse.
4. Some parameters are missing but if you give me a few days I'll try and add the rest.
Now the good part, it works plus you can add as many folders as you want and it will happily process them for you.
Enjoy. If you have any feedback please post. The download only includes the Intel Enfuse binary. If any one needs the PPC version please let me know.
Happy Fusing !
Matt
