Aura-135-004-23

* Sunpak 622 with eBay 89b filter taped on. (Note: I suspect this filter may not really be acting like an 89b, but I'm not sure. In any case, it's quite thick, and as a result seems to be creating quite a bit of light loss.)

* Voigtlander Bessa R with 35mm f/1.7 Ultron. Hoya R72 on lens.

* Prefocused on door.

* Shot wide open, flash full. (Note: As you can see, this yields roughly correct exposure at about 4-5', but is underexposed at 8-10', where the point focus is.)

* Efke IR820 Aura -- 10.75min. at 67.5 degrees f. in D-76 1:1

 

Conclusion: This flash/filter combination does not have enough power to really make for practical shooting in most situations. The working distance is too short even wide open, except for extremely intimate camera positions, i.e., within arm's reach of the subject.

 

I will try again with the Sunpak, IR820, and a Lee #87 gel filter. B&H recently shipped me one that had been on backorder.
