New issue 347 by nicola.a...@gmail.com: Extending the EAEB (Extended
Automatic Exposure Bracketing)
http://code.google.com/p/400plus/issues/detail?id=347

The current EAEB (Extended Automatic Exposure Bracketing) is limited to
maximum 9 frames. Since I need more frames for a scientific project to
generate enough data to be merged later in a single image with high
bit-depth, in the file menuitem.h I have modified the line 269 from

#define MENUITEM_BRACKET(_ID_, _NAME_, _VALUE_, _ON_CHANGE_)
MENUITEM_INT(_ID_, _NAME_, _VALUE_, false, 3, 9, 2, 2, 0,
false, "%1u", _ON_CHANGE_, NULL)

to:

#define MENUITEM_BRACKET(_ID_, _NAME_, _VALUE_, _ON_CHANGE_)
MENUITEM_INT(_ID_, _NAME_, _VALUE_, false, 3, 33, 2, 2, 0,
false, "%2u", _ON_CHANGE_, NULL)

This allowed me to shoot up to 16 frames darker and 16 lighter than the
central exposure value.

Setting more than 33 frames seems pointless because almost after 25 frames
we expect the images on the extremes to be all black and all white.

Thanks.

More than 9 exposures is probably overkill for any "normal" use, but I am
not against expanding the range.

On the other hand, won't it be easier for you to use the BULB mode for the
EAEB script (see
https://code.google.com/p/400plus/wiki/UserGuide#Extended_AEB_In_BULB_mode)?
That way, you can define the start and end point of your sequence, and the
script will make as many photographs as needed.

According with the documentation, seems that in the "Extended AEB In BULB
mode" you can only have 1EV separation between shoots, while with the above
change you can have 1/3EV separation.

Yes, EAEB in BULB mode has a fixed 1EV separation; but that can change,
too. Question is: do we prefer to have 32 shots in "normal EAEB", or a
configurable separation in "BULB EAEB"?

I personally prefer to extend the EAEB option since it is more intuitive
and it is very small change. Thank you for taking this into consideration.
