Extended enfuse and enblend documentation (was: Re: [hugin-ptx] Re: ImageFuser 0.5.7 released)

[Harry van der Wolf]

Hi George,

As mentioned before: dr. Christopher Spiel wrote an extended enfuse and enblend manual. I hoped these would be added soon to the enblend/enfuse trunk but maybe that will take some time, but I think the info is so valuable I decided to put it on my website at

<http://panorama.dyndns.org/EandE-documentation/>

The manuals you will find on this page are written by dr. Christopher Spiel and contain a wealth of information about the use and possibilities of enfuse and enblend. As already said: I hope that these documents will be added to the enblend/enfuse trunk soon as they can also be added/converted as man pages for the programs.

There are a couple of tools "out in the open" to convert html to (media)wiki, or to convert postscript to (media)wiki, but I was not yet completelely succesful (and limited in time). Otherwise I had put them on wiki.panotools.org immediately.

These documents are released under the GNU Free Documentation License which makes it possible for me to publish them on my website.

Please note that this is not my work at all and all credits go to dr. Christopher Spiel.

The enblend manuals are in a "text only" format. The enfuse.pdf and enfuse.ps versions contain numerous graphs to explain the (complex) information further.

With regard to your ghosting, you could read chapter 6 fo the enfuse manual and also take a look at <http://chdk.wikia.com/wiki/DoF_Stacking> as I think that the last part/picture explains what you mention.


Hoi,

Harry,
Thanks that worked pretty well ... I did an extreme example with 7
shots one focused on each cup in a diagonal line across a table.

I got slight ghosting around some of the cups ... any idea where I
should start experimenting to get rid of it?

all the best

Harry,

THANK YOU!

My next question was going to be "how can I get hold of the documents
by Christopher Spiel that you mentioned?"!

I have downloaded the PDF file of the document on enfuse and given it
a very quick skim ... it seems to have some really useful explanations
and advice.

Thanks.

all the best

George

Thank you, Harry!

Benn sort of skimming through the HTML. Wanted to print the PDF, but it
seems to have an issue with a font and is unreadable here :(

Hoy Harry.

If you can get a hold at the original LaTeX-Sources (the documents
look a lot like it :), a conversion from this to (Media)-Wiki should
be quite straight-forward with pandoc
(http://johnmacfarlane.net/pandoc/).

For work purpose I have quite some experience with conversion of LaTeX
to other formats (let's say my boss insists on getting a .doc to
read/edit instead of a .pdf :). I'd be happy to try and give it a go
with it. Do you have the original .tex-source or "just" the html and
pdf-files?

Cheers.

PS: The pdf seems veryreadable here (Windows 64Bit, Foxit-Reader at Work)

Hi Harry, if you want somewhere to put these you can add them as a hugin sourceforge file release and delete them when they get a more permanent location (or leave them there).

I didn't even think of this. I'll have a look at it.

Yeah, I saw that too. I opened the pdf's at work where I have to work with this rare, exotic, non-standards supporting, own standards-creating OS  ;)  and had the same issue. I will have a rerun on the postscript, replace the fonts that unix alikes do support but windows doesn't and create a new pdf.

I just put the source code on the same page: <http://panorama.dyndns.org/EandE-documentation/>

Anyone being able to create a nice MediaWiki format is welcome. I used a couple of tools to convert both the tex(i) docs and the html to mediawiki. That delivered a 90% correct MediaWiki document, but the last 10% is the hardest one. With some time you can do the final 10% by hand, but currently I don't have the time (actually I don't want to put in the time right now).


I will have a look at the conversion of the postscript to pdf with some "world-wide available" fonts.

I recreated the pdf's from ps on my Ubuntu server with ps2pdf. I added them to my website under "windows optimized". They do now function on my son's XP box too.

Please try.
