gimme some feedback pls if u can
ur images 26 n 27 they dnt have the same orientation
etc..generally the diff between 1/49452 and 1/98905 is very small but u can see the diff in the histogram..there shall be a slight shift in the histogram to the left..but ur histogram shows the opposite!!! the shift is to the right!!!!

But if you take a look at a Makernotes you will see that 26 reports exposuretime: 1/49452 and 27: 1/98905 - so pictures are in the right order. Also - all pictures were taken in the same light conditions. Examining histogram was a bit surprising for me too. Maybe new "strange thing" discovered? But I still think 1/49452 and 1/98905 are the same. Shouldn't there be a noticeable difference between two photos taken with twice longer exposure time between them?
Hellow, Jive!There is no firmware or firmware dump for your camera now. May be it depends from u too Please read this page http://chdk.wikia.com/wiki/Porting_the_CHDKThanks
