A symbolic marker of my first blind and bumbling stab at a panorama, operating under the unwarranted and misguided supposition that Hugin might be intuitive and user friendly. Hey! Everyone starts somewhere...

Although 23ers may not be altogether thrilled with the arrival of the impending experiments of a neophyte, I thank kato for telling me about the software, and reassure everyone that I have now taken the trouble to acquire a tutorial. :)

Lol!.. It's a start, so don't be too tough on yourself. If I were to suggest anything, the horizon can be straightened in Hugin and it might pay to set the camera to manual to avoid Auto white-colour-balancing. You'll have even better results, I promise!

As an aside, I hear the new stitching utility in photoshop CS5 is quite effective.

Thanks for the encouragement, Kato, you are so kind.I have done a little reading and am trying to bracket my shots so I get three pictures of everything 2ev above and below the normal exposure. I'll try turning the auto white balance off too. The tips are most appreciated!

Happy to help Creeksong. I wouldn't worry about auto-bracketing for your panos. Instead look to set the exposure manually and shoot the sky and the earth separately with about 1/3rd overlap on each shot. That way when you stitch it together, you'll have the best tonal range for every element.

Hope that makes sense?

So only one shot of the overlapping areas at the best exposure I can, each set separately? This kind of help with technique is just what I need right now. and one of the reasons I spend so much time paying dues. You are most kind to offer it. Thanks from Eric Rothchild

Hi Eric, I'm not quite sure I explained very well. In the case of the image above, I would shoot one horizontal band for the sky at the right exposure (say f10/500sec ?), then lower the shutter speed and shoot another horizontal band for the foreground (f10/200sec?). Make sure there's enough overlap in the two individual bands to join it all together later on in Hugin. Good luck!

Although I am quite busy right now and don't have much time to spend playing with this new knowledge, Give me a week or two and I hope to do you proud. The time you are spending to help me is a valuable gift, and yes, I didn't understand. But it's making better sense now. More light in the sky less on the ground. not rocket science. But I was changing the F stop and using the same speed in my latest attempts at this. For scenery, would you use the highest F stop applicable in order to provide a long depth of field?
Mark Andrews April 22, 2010, 08:19 AM
haha.. almost. You want to restrict the light in the sky (faster shutter speed) and increase it for the foreground (lower shutter speed). That way you'll have an "even" exposure from top to bottom when it's all stitched. I would keep the f-stop the same throughout otherwise you'll have too much variation amongst the images. Keep the f-stop around the middle ... f8-f12 or so and the depth will be fine. Your images will actually get blurrier the more extreme you push the aperture.

"Your images will actually get blurrier the more extreme you push the aperture." What a gem! Why didn't someone tell me this 50 years ago when I started doing photography?!? This conversation is way more enlightening than I ever could have expected. ( yes, pun intended) No wonder you have the high praise and respect of everyone here. You deserve it! Again, thanks for taking the time to help me.
