I have to do a shoot that requires a fairly wide angle and which will be enlarged and framed for presentation as a gift.

The wide angle lens is on order but not yet arrived and I need to have the shoot completed by today.

Any suggestion as to the best setting??

The A640 has L through to W as setting options.

put the camera in continuous mode, then do a slow pedal turn while you hold the shutter trigger. Shoot about 3 or 4 shots as you rotate and then stitch them together.

Thanks DJ ...

Should I then just set the camera on "L" to do this (3648 x 2736)?

Also, I want to shoot about 1250 speed - any suggestion for the F stop?

L is good. Why such a fast shutter speed? I usually shoot between 640-800

To stop blurring - anything less I have found reduces the clarity of the images. This is based on the Casio Z850 and the T-Rex 450 however so I may try slower settings on the 640 and see how it goes.

What aperture F Stop are you using DJ??

*copy from another forum*

What are you shooting from? A mast or aircraft/heli?

If it's with the mast then you can 'simulate' a wide-angle lens by taking four images in a grid:

O O
O O

and then dropping them onto PTGui.

If it's from an aircraft/heli then you just have to shoot as many pictures as possible of the target and hope that some will overlap enough to give you the wide-angle view you need .... Either that or fly further back

Again, it depends on the application ... if it were on a mast I would suggest using Manual mode (if you have a downlink) and an aperture of around F5.6 - this is around the sweet spot for maximum sharpness. Then adjust the shutter speed to suit the exposure. If you don't have a downlink, set it to Av mode and F5.6 ... it will pick the best shutter speed. If it's from a aircraft/heli then you want to use a good fast shutter speed of 1/400s upward. Set the camera to Tv mode and set the shutter speed to 1/400s and take some test shots - increasing or decreasing the shutter speed depending on the conditions ....

Hope this helps

David

PS. Use the L setting for resolution and Superfine for the image quality.

Thanks David...

The camera is on a T-Rex 600.

Also - what Aperture setting for this setup is best??

Around F5.6 I would say. But if this would force you to use too slow a shutter speed, then just adjust the aperture value to suit ... you don't *have* to operate at F5.6, but it will help you squeeze the maximum sharpness from the camera ...

Cheers

David
