Reaching Out

I have an excellent 300mm ƒ/4 lens and would like to increase the magnification using a tele-extender. I’ve been told that this will degrade the image quality and I won’t be happy with the results. What is your experience using these add-on magnifiers?

Time For A New Printer

The Mobile Photographer

I’m limited to movement in a walker or electric cart. I would like to start photography again. Is there a tool that could be clamped onto the walker or cart that would hold a camera out of the way while I move into position and then would permit the camera to be swung around to take the picture?

More Depth Of Field

Using A Tilt/Shift Lens • Intensify Now Or Later? • Protecting You From Yourself • Patience • Super Scans

I’ve experimented with tilt/shift techniques. With all of the digital techniques available for altering depth of field (as well as perspective control), do you still find tilt/shift lenses useful? Helicon Focus seems to solve so many depth-of-field issues.

Simple Panoramas

What’s the best technique to obtain a panoramic image without going in for expensive equipment such as panoramic cameras? I have a Canon EOS 30D and shoot with a Gitzo tripod and Kirk BH-1 ballhead. Do I need to capture eight to 10 overlapping images of the panoramic landscape and then stitch them together in Photoshop?
