This was with the 300 mm. lens, two images blended, though in hind sight I really needed 3 to get the nearest part of the fibreglas in focus.
This was shot with the 75 or maybe the 35 and below is a 100% clip from somewhere in the middle. I'd love to see a six foot print of this image.
Shot with the 120, aiming upwards, perspective corrected in Photoshop, Command A to select all, Command T to transform, and Command Drag to stretch the corners to correct perspective and trim exactly to requirements.
