I would like to learn how to do macrophotography with my 8X10. I realize that close focus may take my bellows beyond its normal travel range. I would like to be able to use my standard lens (CALTAR II-N 360 mm) for macro photography. Perhaps have someone's face fill the entire frame. Is this practical with 8X10?

I’ve been playing with this on 4x5… but have been having a hard time figuring out the minimum focus distances…

So… I’m responding to follow and learn…

The 360mm needs 720mm bellows at 1:1, so it depends on your camera and whether you are willing to buy extension lens board.
At 1:2 you will need 360+360/2, and at 1:4 360+360/4 and so on.

I have done 3-1 Macro with a 360mm Plasmat using nearly 6 feet of bellows onto 11X14 X-Ray

Let me know if these links work as i am having problems with flickr

Here is Matt M doing 8x10 macro and discussing lens focal lengths. This is quite good!

Yes, my first link is Matt

LF Macro is a great winter sport as I can do it inside

I have a dedicated Levy copy camera that has 3 Calumet backs, 4X5, 5X7, 8X10 and a Horsemen, Sinar size lens board mount

I use very bright lamps for focus and setup, then may use other lighting

I now use Schneider Kreuznach APO Symmar 120mm f/5.6 MC Lens Copal 0 as it is a darn good lens for Macro

You don't need a special lens, just do it with what you have

Did this ages ago with a vertically mounted 4x5 crown graphic, reverse mounted 55mm micro nikkor lens, with single desk lamp at a strong angle...of watch movement components floating on the surface tension in a dixie-cup of water upon which is also "floating" (by surface tension) a layer of aluminum powder. Exposure was long (I think about one minute), done with only the light switch:

Shorter focal length lenses that can never deliver a proper image circle at infinity focus, but can easily cover the film format required at close up distances. This works to a significant advantage as shorter focal length lenses reduces the camera/bellows extension needed to achieve a given image ratio/image size on ground glass and film. There is no real limit as to how close any given view camera lens could be focused.. Optical performance will suffer much with lenses designed and optimized for infinity -vs- lenses designed and optimized for life size or 1:1 image ratios. Exception to this would be symmetrical lenses such as the APO process lens (Dialyte) works GOOD at infinity focus to life size 1:1..

Close focus, simply add camera/bellows extension as needed.


Keep in mind, view camera is servant to the demands of the lens and image goals.

~Then comes the FAR more serious difficulty and challenge of lighting/metering for proper exposure, which is more often than not the real challenge to macro or similar images be it film, digital or _ .
