LaurensB, nice to see good ideas
believe or not but i have this already in my driver. it's based on manual shutter speed selection (zoom keys) and here is small example, maybe not the best but i have no free time (and opportunity) to make something more "spectacular" 
exposure time is 0.75s (can go up to 2s as normal manual shutter speed without flash)
Already done some nice try's with Genus old driver :
http://my.opera.com/LaurensB/blog/2007/12/20/long-exposure-shots
But I am looking forward to your version, BTW is 2 seconds the limit? I thought the W810i could go up to 8/30 seconds! 
Edit :
It isn't exactly the same as told about on that website but I'm sure I will be able to give some examples about what I mean with a super cam driver that supports shutter speed:P
Basically the only thing we would need for this is control of the flash sync (flash shoots at the start of the shot or at the end) and the exposure time during flash I don't know if the first is possible but I am quite sure the second on is!
Looking forward to more development  I am sure we can do some impressive stuff with this

yes, 2sec is the official limit for 2mp/3mp. shutter speed mechanism seems to be identical like in k750/w8x0. they were able to do ~7sec exposure in extreme conditions but this was max. EXIF still was saying 2sec and that's because of slow shutter speed which also has big influence on exposure time

Awesome That's really good to know
Btw : quick question, can we disable the auto-noise reduction? It can make pictures very ugly, a good example would be this :

The K750i usually has more detail in the pictures (at a lower resolution) I haven't been able to figure out if it's because the compression, sharpness filter or noise reduction but my guess is the later one. I don't have a K750i at hand to prove my point.
Thanks for all the great work! |

bugs in EXIF exposure time (left is EXIF, right is real value)
4/3 - 3/4
3/4 - 4/3
3/5 - 5/3

as far as i know K800 don't have noise reduction methods. this rather depends on sharpness, ISO, compression, colors saturation... separately or all at once one more thing to note is bilinear filtering used for pixel interpolation in zoom. default state is always enabled but disabled can improve sharpness on x1.0 pictures. unfortunately i can't find register (cmd5b from k750 doesn't work)

Yes there's no noise reduction like others are claiming. A white balance filter is not a noise reduction filter. JPEG compression isn't either. |

Raider I think it's for the focus algorithm, when in Doc mode it takes only the center of the screen for the focus, and in other modes takes an average of every points on the screen (AF windows)

i did small test with it. with 6sec delay in seq_set_prop_9_6 code i didn't met any delays during scene & focus changes. this subproperty seems to be unused

Maybe is used when in spot metering? I'm just wondering... You tested the delay when in Macro mode too? Maybe multiple AF windows are used not in normal mode

seq_set_prop_9_6, it holds two focus commands
#SET_REG(32,04)<<<< used by protrait scenes Use multiple AF windows, normal. focuses the whole picture but only has limted range.
#SET_REG(32,05)<<<<< used by document scene only, // Use multiple AF windows, full range. uses the full power of the autofocus system.
#READ_REG(32,$r2 0 0) // Check what reg 32 contains
$b0 00 1 7 // Mask out LSB bit
$c0 00
i guess all that just tells the autofocus what to select. |

seq_set_prop_9_6 isn't used at all no matter of scene, focus, light metering etc. this could be used in testing procedures during development

Raider, I can see you are already using your 6.1 version for K800!
Do you plan to release it soon? |

yes, of course but i don't know when. i'm still fighting with problems:
high priority, must be fixed:
- very slow change between draft (we can apply EM here) and half release (must be enabled to take snapshot) modes in seq_ss_X
- AE lock doesn't work on infinity focus
low priority:
- AF macro range only scan doesn't exist. macro mode (full range) scan is veeery slow
- bilinear filtering (zoom) cannot be disabled. disabled can improve sharpness of x1.0 pictures

i don't understand what is af macro range only scan, k800i just has 4 differeny focus types.
are you saying the bilinear filtering is on all the time, even when theres no zoom???. |

in k750 driver were used only 2 values - normal range (no macro mode) and full range (macro mode) but there was also other: fast normal, fast full, macro only. if we have normal and full (normal+macro) then i still believe that macro only is available too
are you saying the bilinear filtering is on all the time, even when theres no zoom???.
yes, this was in k750 and i don't expect different situation in k800. don't ask me what for bilinear filtering for x1.0 pictures
