Hello all

I've ordered that camera, and it will ship in couple of weeks, but I want to get raw image, to check, how the camera performs by itself (mean no sharpening-saturation-noise reduction). I've read almost all reviews of A200 on the internet, but none of them features a raw file to download.

Can anyone send me such file by email, or point to site where I can download it?

oeps, mistyped

you need to download this file:
http://www.heck.be/PICT0972.flv (if it shows www. heck. be you should change it to w w w . h e l l . b e

and rename it to PICT0972.MRW

this forum probably changes the word h e l l to heck, very strange!

i seems as that my webserver doesn't recognize the .mrw file and won't show it

Thank you very much!

I've downloaded it. But I have one question. Why this image is so overexposed? it was incorrect manual settings, or camera automatics messed up?

i too downloaded the picture...

and it does look overexposed or something...

but now it's the first time i really unerstand what RAW is all about...
i opened the pictore with Adobe Photoshop "Camera RAW" , and played with the exposer settings , i took it all the way down , and i now can see the little kite which is stuck way up on the tree at the right side of the photo.

i don't belive this can be done with a processed JPG file.

cool.

"i don't belive this can be done with a processed JPG file"

True - this is because RAW files (4096 levels) have 16 TIMES more possible brightness levels per colour compared with JPEG (256 levels). That is why you can change exposure level by +-2 EV when openeing a RAW file.

Yes, i know the pic is a bit overexposed, but it was due to the strong sunshine at the right of me.
I'm still a novice using my A200. What should i have done to prevent this overexposure?

I am not a pro , so i am not 100% sure about what i am about to say...


i think this has nothing to do with the A200…
the camera took the exposure measurement probably from the center of the frame where the bridge is.
so the bridge has the "right" exposure , and the sides of the photo which are not part of the bridge are "wrong" exposure.
I see in the manual (which I downloaded from KM web site), that you can choose what zones in the frame should be the points of measurements, for the exposure.
You might also use a tripod , soot 2 frames with 2 deferent exposures one for lights and one for darks , then mix the 2 using Photoshop.
