Unfortunately, I have not seen your code
But none of RAW converters supports this RAW.

I don't have any experience with shooting to RAW (even with my A710),
however I'm not very happy with it :(

If you want, you can look into the attached code.
It is allbest's build with my some modifications for A710,A570 and A460.
A460 support is not finished yet.
Thanks for any comments.

Thank you for the A460 Support! Great work!

I'm checking this beta-version with my A460.

Generally work this version. But the RAW-modus do not work. The camera save a file (6400kB). This file show me a Picture with noise. I tried it with Photoshop CS3 after renaming the file xxx.crw -> xxx.raw

Scripts also doesn't working properly. They are starting, for examble bracketing, but before the camera making a shoot, the script doesn't anymore to work. After few seconds the camara shoot down.

Other functions seems to work, other language, other fonts .....


Sorry for my bad english. ;)

Live-histogram works fine.
RAW file - same issues, cannot open file but at least it's created.
AV, TV, or ISO override won't work - camera hangs on half-press
Focus override does not seem to change anything.
Tested both in auto and pseudo-manual mode.
DOF calculator shows something, I haven't tried to correlate with real measurements so I assume it's correct.

I could not open any file crw or cr2   :(

But now my little canon a460 has many things
I set the menu in Spanish with the language file
Live-histogram is excellent
Zebra works fine
I make a script for exposure bracketing and this works fine.

The script is simple
Need a few things before run:
- script works in mode dial M and SCN
- Exposure set in 0
- Go to "FUNC SET" make sure to be in first element ("Special Scene Mode" or "Manual Mode") and exit of "FUNC SET"


Code: [Select]
@title EXP bracketing a460
@param a Number of +/- steps
@default a 2
@param b Step size (1/3EV)
@default b 3

if a<1 then let a=2
if b<1 then let b=3

sleep 300

print "Preparing..."
click "set"
sleep 200
click "down"
sleep 100
g=a*b
for n=1 to g
    click "left"
    rem sleep 5
next n
f=a*2
for s=1 to f
    rem print "Shoot", s, "of", a*2+1
    shoot
    sleep 60
    for n=1 to b
        click "right"
    next n
next s

rem print "Shoot", a*2+1, "of", a*2+1
shoot
sleep 60

print "Finalizing..."

for n=1 to g
    click "left"   
next n
click "set"

end

Saludos

Hello,

i own a a450 powershot, it seems to be the same as a a460 but has 3.2 zoom and not 4.0

When i'm trying to boot the a460 firmware the camera display shows "Firm Update - Update File Error!!!".

Are there any chances to get the a460 firmware working on a 450 powershot?

is so, i would be very happy :-))

thanks in advance

greetings piwi

WARNING: I'm not responsible for any damage / useless work caused by that tip.
I don't know the actual changes, but it seems that this is only an internal camera prevention,
it rejects the firmware for a460,
you can use pakwif for that propose.(it is in blinker.rar /blinker/fw form Index of /hdk/blinker/)
Just call pakwif.exe PS.FIR DISKBOOT.BIN [camera code]
and you should have it.

P.S.: You can get the [camera code] like that:
- place emty ver.req file in the root-directory (top-most) of your sd
- on in review mode
- press and hold set while you press disp button
- the p-id should show up: something like: P-ID: 30C0 PAL
the you have the camera code: 0x30C0

So now any clarities  should be removed. ::) :D :) ;) :lol
If not read on:
You can also use only DISKBOOT.BIN like that:
Make SD-Card bootable at pc and put DISKBOOT.BIN on it.
