Hi Klaus, I realise you wer testing the lense and assume that ypou have not processed the image. I was wondering if the neutralhazer filter in APG would help if you had to use this image.

Hi John!

I tested the NH filter - it didn´t help here because of too much haze. The filter can´t do miracles . . . ;):cool:
I´ll look for the examples and show them here.

A real NH filter on the lens might have helped better.

best, Klaus

Hi Klaus,

I have been struggling a little when doing my pano's with my 300mm over a landscape... perhaps you can give a little insight here, sorry if its totally obvious

Ok, here goes - do you fix the focus or do you let the camera auto-focus on each frame?


thanks

Henrik

Hi Henrik!

I did my shot using Josef´s head with xml files. In a first experiment i used different focusing on the foreground - but the foreground was too close for a 300mm: between 3m and 10m.
So i used a fixed focus - i wanted to have an unsharp foreground.

Basically i would make a shot like yours - which i like much! - with changing focus slightly (!) from foreground to the hyperfocal distance. Changing focus too much results in too big scaling-differences for the stitcher and you´d need to do focus-stacking.

I never use AF or another automatic. Fixed WB, fixed exposure - and always RAW.

Josef´s head is extremely sturdy and weights about 4Kilograms. So long exposure is not a problem at all even with 300mm or 600/800mm. Essential is a mirror-lock before each exposure. Josef added a motion-sensor which detects the slightest shaking. It´s switchable of course and we´re adjusting it´s sensitvity at the moment. So we can set a short "dead-time" and the sensor gives a "go" after any kind of shaking is gone. That saves fractions of a second - firing the camera about 700 times for a mosaic or a highres sphere this means a lot of time.

I stopped 2,3minutes for a 700MPx sphere using a 35mm lens on ff. That´s not "speed-mode" but definitely ensures sharp images even using 1/60sec instead of 1/1500sec . . . :D:cool:

best, Klaus

Hey Jo!

It´s a nice place, isn´t it. We did a tour for them:
http://www.schloss-drachenburg.de/content/virtueller_rundgang/virtueller_rundgang.html

We will do the shot again when the weather is very clear - maybe with a 400mm.
We´ll shoot the castle in an early morning-light and the rest in the late afternoon
both from the exactly same viewpoint.

best to you, Klaus

Klaus,
do you know that the "donkey trail" from castle to Drachenfels is actually closed because of fallen rocks?
