I'm not sure this is the correct forum for this, but here it is anyway.
My goal is at least a 180 degree 20 gigapixel
panorama of a cityscape. The final output will be in a 10x1 aspect ratio, so in order to account for the height of some buildings, it may need to be more than 180 degrees.
We will use Canon 5D mk2 with a 400mm and/or 600mm lens. - will this be too heavy for the Panogear/Merlin?
We'll be using the panogear head. I am not the main photographer, but will be assisting in the stitching. The main photographer is new to shooting panorams, but we have done a test what we shot manually without a rotating head at 400mm. Here is some documentation and issues I had: http://www.kolor.com/forum/t14947-obviously,i-have-no-idea-what-i-m-doing.i-thought-i-did-any-ideas
- Even though we didn't do the shoot correctly (needed same number of photos for each row, with similar overlap), I am quite happy how the stitching for the actual city turned out. (see image).
My question is, what are somethings that I should be aware of for my first shoot to go smoothly? What are some things that you wish you had known when you first started doing gigapixel photos? Also, is there any good tutorial for shooting gigapixel photos with the Panogear and gigapano pro? (I already have the DVD from Kolor)
I wouldnÂ´t recommend the Merlin with lenses above 300mm. It gets VERY slow above 105mm because the decreasing angles result in a permanent "go to" modus instead of (faster) "move to" and then (slower) "go to". ItÂ´s a bit faster using the TC controller - but the head itself is slow motorwise.
The precision is acceptable up to 300mm - using 25 or 30% overlap minimizes the problem at the cost of shooting more images.
Take care that you use mirror-up above 200mm lenses. Therefore you must set a sufficient wait-time - thatÂ´s the time the head waits for the camera before the next move - because including mirror-lock the camera takes a bit longer to shoot.
Use a very sturdy tripod, avoid placing the setup on a vibrating plane like bridges with traffic and so on. Also donÂ´t place it near a street where trucks come driving along near the standpoint - the setup will be moved by wind.
Take care to plan the shooting in terms of changing light - shooting 20GPx using a Merlin with 300/400mm i estimate around 2-3 hours at least.
I guess your lens-/camera combination with 400mm and in particular 600mm indeed is too heavy for the Merlin. But given you donÂ´t have much vertical moves you might use a counterweight on the foreend of the rail/mounting to compensate the weight.
Run a test with a narrow angle before you start to shoot a wider one
