Camera Talk / Re: How often do you replace silica gel?
« Last post by Les Olson on Today at 08:56:58 »Silica gel only absorbs about 25% of its own weight in water. At 30 degrees C, the maximum water capacity of air is about 30g per kg and the density of air is 1.22 kg/m3. So if you have 0.1 m3 of storage to protect, you need to absorb 0.122 x 30 = 3.7 g of water, so you need 15 g of silica gel.
I use a dry cabinet. It is much more effective and cheaper in the long run.

Camera Talk / How often do you replace silica gel?
« Last post by lucaspalm on Today at 08:23:14 »Hi,
I have a simple question about silica gel / moisture absorbers used for storing camera gear.
How often do you usually replace or regenerate them?
Is it based on time, color indicator, or storage conditions?
Just asking for general practice.
Thanks.

What the Nerds Do / Re: Nikkor 10.5mm f/2.8 - 62mm filter threads modified
« Last post by toups on Today at 03:02:35 »Thanks for the info. Based on the warning on the service manual and your confirmation, I definitely will not remove the rear element group until there is no other option and the need is great which hopefully will never happen.

Processing & Publication / Re: Advice on photographing paintings
« Last post by ColinM on Today at 02:43:38 »Constant light is definitely the best way to go, you can tweak until there are no reflections.
Edit your images while you have the art next to the monitor. Digital renders a lot different than you see,,,
Thanks Eric & Ann
My investigations continue
Nice idea Airy
I dont have access to that lens this time, but if there's a next time maybe.

Erik makes a good point — especially if the artist paints with acrylic colours!
(I have had bitter experiences with Acylics!!)

"...Would you be willing to tell me what adapters that you found that allowed for mounting that lens to the front lens board..."
Most (if not all) of the posts on this board regarding this lens are by Michael Erlewine.
The Macro Varon series was renamed "Pyrite" by Schneider Kreuznach some time ago. I believe that the specific lens Michael used at that time was the 0.5 to 2X version. This is a manually adjusted "float" (variable β) lens.
Michael posted an image of his setup here: https://nikongear.net/revival/index.php?topic=7291.msg117687#msg117687
The mount of the lens is V38. Schneider sells various adapters. See https://schneiderkreuznach.com/en/industrial-optics/lenses/large-format-lenses/pyrite/f4-5-85mm-0-5x-2-0x-v38

For my own work I use a 6X9 Cambo Ultima II that I've converted to be similar to a Cambo Actus XL. I use the Actus type front standard most of the time but I have retained the original front standard due to the availability of recessed lens boards. This enabled the use of several wide angle lenses on F mount cameras that would otherwise have been useless in this setup due to the flange focal distance being too short.
