Cleaning a corroded battery compartment- The Lensbusters way

I've been buying up gobs of 35mm SLRs manufactured from the 1960's to the 2000's. Many of the cameras I buy have been sitting in a closet for decades. One side-effect is that often the little button cell batteries have corroded. I've come up with a novel way to deal with said problem.

So, here goes. Wait until after-noon, unless you are on vacation, then after 10am is ok. Then prepare yourself a gin and tonic. After you've finished the first G&T (if you don't like G&Ts you are also able to have any drink that comes with a lemon or lime wedge, a Mexican beer, a Kristalweizen etc will also do.) Be sure to squeeze most of the juice into your drink, or simply eat the fruit inside and hold on to the peel.

Now, open your corroded battery compartment. Carefully dispose of battery (I keep a plastic peanut jar repurposed for old batteries to take to properly dispose of.) Take a paper towel and a pen or other similar item and rub around and get out all the white dust you can inside the batter compartment and the battery door.

Next, take the lemon or lime wedge and rub it around inside the battery compartment. There should be a little tiny bit of citrus juice (an acid) that helps cut through the (alkaline) corrosion. Once again, take a piece of paper towel or similar and wipe the effected areas.

Now insert new battery and (hopefully) Voila!

(Note: Not responsible for any damage to either your G&T or your camera or other item - this usually works for me but your mileage may vary. Also, be sure to wear proper protection and abide by all laws. If in Saudi Arabia be sure not to use real alcohol for your drink, I don't want to be responsible for anybody's beheading.)

Linhof Serial Year List - Salomon Says

Recently I've acquired a few Linhof cameras. I got a 5x7 view camera from Oakland Museum's White Elephant Sale. Later I stumbled upon a Color Kardan 90 Jahre Jubalaeum edition on Craigslist. And more recently, I found a "baby Technika" 2x3 (6x9) at Oakland's East Bay Depot for Creative Re-use. Not knowing much about Linhof large format cameras, I tried getting more info online, and came across a strange thread on the Large Format Photography Forum . Basically on this thread various Linhof owners ask a guy named Bob Salomon what year their Linhof was made. And the thread is over 100 pages long! Sifting through that thread is mindnumbing. Why Bob doesn't just publish the list of serial numbers is beyond me. Maybe it's just nice to feel needed. So I started compiling a spreadsheet of the serial numbers and the answer Bob gives. If you don't feel like spending a couple days reading this thread to get a hint as to the age of your Lin

How to stop annoying Corel pop-up ads

Corel has done something extra sleazy. For those not familiar, Corel has been making image editing software for as long as I can remember. The Canadian based company is known for budget graphics software including Corel Draw! (Similar to Adobe Illustrator) and Paint Shop Pro (Similar to Lightroom) as well as some other products. The price of their software makes it hard to resist. I bought a few of their products years ago. Recently ads started popping up in Windows (not on a web browser, but just in the right corner of my monitor. Those ads were for Corel products and would float over all other panes in my Windows. How sleazy is that?! So I found a way to get rid of the ads for good. Or at least until you install another Corel product. If this happens to you, and you find it as annoying as I do, follow this instruction. First, hit control (+) alt (+) delete and select task manager at the bottom. If you look at your task manager, you'll see something called "background

Who Makes Ultrafine Film?

One of these 120 paper backings stands out as being different. Not a big surprise, since one is Kodak, and another is Ilford. But our mystery film Ultrafine has the *exact* same backing paper as seen in this scan. What does this mean? There are a few possibilities that come to mind. It's always possible that the backing paper is made by a third party I suppose. Not likely, as there isn't much of a market for 120 film anymore, and I've never seen another non-Ilford film with the same backing paper. So is this mystery film, Ultrafine actually Ilford then? Another, more likely theory is that it is made by Kentmere. Kentmere and Ilford are both part of the Harman group . In researching this I just read that Harman was the name of the founder of Ilford company in the late 19th century. So how is are the Ultrafine (E)Xtreme films? I bought a bulk roll of the 400 speed. Frankly it's pretty grainy and soft. I don't hate it, and I'm trying to work with the grain.
