Cheers Will,

I don't feel so bad about the dark stripe now!

Sadly it doesn't seen to be just a one off - all the shot that session were the same.

I've just looked back at these below I took a month ago with a similar setup. At the time I though the darker left-hand edge was just the way I had lit it (quite liked it at the time), but I don't want this to become known as my 'style', with every shot like this!

When I get some time I will try a few similar shots but using available light, that way I can at least see if it is a general problem or one when I'm using flash.

Aha, just thought of something - should I have had the flash mode in 'wireless' as I was using a wireless trigger? - It was in the normal mode - no idea what difference this would make tho.

Hi Stefan,

I can give the firmware reinstall a try, but won't get a chance to try a reshoot under similar conditions until later in the week now though, as I'm going to be busy.

Out of interest, I just tried photographing a blank piece of white paper on the bathroon floor under under ceiling light using Av (aperture priority) and didn't get the same result, the exposure looked pretty even across the frame.

I'm even more confused now!

Thanks John,

still it must be a camera problem rather than a lighting problem for the effect to move with the camera,

Hi John,

not using the built in flash, just the two studio strobes, one behind / above the subject, and one just to the left of camera.

I've not changed the lighting setup between shots here, just tilted the camera over to get portrait format - the dark area has followed the camera orientation.

I can only think it's something to do with the shutter - does anyone know what direction it travels in? If it's top to bottom in lanscape orientation I can't think of anything else.

Cheers

Sorry - cross post.

Just pulled out the lens's built in hood a bit - its circular so I can't imagine it only blocked one side. It's got me stumped!

Hi Stephen,

It was on the 'X' (flash sync)setting!

Cheers

Hi All,


I was taking some shots of some jewellery my wife made and noticed there was a graduated effect of the exposure across the frame. See the pictures below. Notice the grey band on the bottom of the top picture, then on the left side of the second pic.

It only really became apparent beause I switched from portrait to landscape and noticed the dark section moved from the bottom of the frame to the left side when I tilted the camera over. I had thought it was just fall-off of the lighting nearer the camera until I switched to portrait.

Set-up as follows:
K10D - f5.6 on 'X' setting
Pentax 35mm Macro Ltd with Kenko 2X teleconverter (tried it without teleconverter, still same problem)
2 studio flash heads, one fired remote and the other slave.


Anyone else experienced this phenomenon, or can anyone explain what it might be?

I'm hoping it's just some aspect of 'user error' and not a fault with my beloved camera!

Any help greatfully recieved!!!!

My wife is Japanese -I've just got her to do a rough translation.

Yves link takes you to a page which says:

"Challenge the next Dream
Super high resolution(?) image the world with a big image sensor. This real ability will be revealed with the CP plus"

Not very interesting I know - but try this page



www.camera-pentax.jp/new/news01/index.html
link

This page reads:

"In this new product, comparing with 35mm full size it has about 1.7 times more pixels(?)

From oneimage the data amount is 100MB - you can understand the impressive image quality of the big sensor by just one look at it."

(?) means there was a technical word the missus didn't fully inderstand herself.

Don't know if any of this will give any clues or not - but there you go.
