Re: [OGD] slide conversion to digital
Can anyone recommend a slide converter that would make this possible. If you look on Amazon.com or an online photo shop you will see the Opteka Digital Duplicator. I bought one for $49 and was surprised at the quality of the reproduction. You also need a digital SLR, like a Canon Rebel, but their 18 - 35mm Lens, works well. Probably a hobbyist in your area has one of these as their price is very reasonable these days. You can certainly scan slides much more reasonably that way. I like it because it is fast and I have much less contrast from the slides than when I use my expensive Nikon Super Coolscan 5000 which cost $1,200 and requires a degree in technology to operate.. Archival preservation of slides would probably cost considerably more than $1.49/slide and even then, you will probably not be completely satisfied with the results. I've had some of mine done professionally, and I can honestly say I have done better myself working at home on my own computer. Scanning is only the beginning of the process. Each slide should be brought into Photoshop or another editing software for color correction and removing the splotches and dust from mold and the copying process. Slides made with an E-6 process film like Ektachrome need a lot of restoration because of shifts of color balance and fading of colors over time. If the slides are Kodachrome they can still be vivid after 50 years... This is usually not included in the price of scanning.

Re: [OGD] Wetpads
First the easy one, PET is what water bottles are made from. Second is you are in a good location for wet pads to work. Here in Florida they don't do much to cool in summer since the humidity is already in the 80% or higher range on many a summer day. In areas with low humidity they work by evaporating water as air is passed over them, as the water evaporates it cools the air, hence the more specific name of evaporative coolers. There are two basic types Aspen Pads (which is what the PET type are) and Cool Cell which are made from a specially designed fibre that has an engineered airflow pattern to maximize the evaporation without compromising the airflow. Aspen Pads and similar are just that, pads of Aspen strings held inside some type of mesh that water is dribbled over. Most that I have seen tend to have holes and gaps in the pad and places where it is thicker than you would wish restricting airflow. The typical installation has one wall of the greenhouse that is the pads with exhaust fans on the opposite wall. If you are subject to frequent power outages as we are you better have a good emergency backup generator that comes on automatically because for them to work all air must be pulled through them, meaning if the fans go out on a hot sunny day you can have some nice cooked orchids in no time. Swamp coolers are not quite as bad as they are generally self contained units that can do some good in a passive cooled greenhouse. I have learned to prefer high pressure fog for cooling and humidifying since they work whether the greenhouse is open or closed. -Original Message- From: Paul Carver [mailto:[EMAIL PROTECTED] Sent: Wednesday, February 27, 2008 01:54 AM To: orchids@orchidguide.com Subject: [OGD] Wetpads Wet pads: Here in Melbourne Australia, I know of only one grower who uses wet pads for cooling humidifying.

[OGD] Humidification
Paul Carver [EMAIL PROTECTED] spaketh thusly: Here in Melbourne Australia, I know of only one grower who uses wet pads for cooling humidifying. This system is a mystery to me, but I have to acknowledge that a much higher % humidity can be achieved than with my small swamp coolers with supplemental misters. Would somebody please explain the 'system' , and where I can resource the 'hardware'. Here we can have hot summer days to 40 deg.C (100F), with humidity as low as 20%. It is a constant struggle in summer to ensure constant high humidity when temperatures go to 100d. F . What are recycled PET pads? PET (polyethylene terephthalate) is a wonderful little polymer that is used in a lot of different applications, including beverage bottles: http://en.wikipedia.org/wiki/Polyethylene_terephthalate Once done swilling the soda, they can either occupy a landfill until such time that the earth's crust is subducted, or they can be recycled. In the case of swamper pads, they probably last for a similar period of time- or until they are gunked up with carbonates and chlorides. Don't know about any mystery systems and how they function in .au, but I did manage to sit in on a talk from the wizards at the Atlanta Botanic Garden (with their excellent Fuqua Conservatory) in which they explained how they managed cold air in a place that's as hot and humid as Atlanta. Recall that evaporative coolers function best at low humidity, making Atlanta a poor choice for the use of such chillers. The architect or engineers or whatever that thought up the Fuqua's conditioning system stole a clever little idea from cotton twine manufacturing; in that industry, the material is processed so fast that the product would catch fire from the friction. In order to counter that, they used air humidified with pads that are wetted with refrigerated water, rather than ambient temperature. So, if one can drop the water temperature to, say, 4 C (down from 30 C outside), a 10-20 C temperature drop in product air could be achieved. This can be boosted by spraying chilled water into the air (before or after the pads- I forget) to absorb yet more heat. Very clever solution. I'm glad I don't have to pay their electric bill, though!

Re: [OGD] Orchids Digest, Vol 10, Issue 63
Hi there Jim, If you've got the time then I would recommend investing in a printer/scanner combo. We have an Epson RX630 printer with a flatbed scanner capable of scanning regular documents as well as slides and negatives. I think we paid about $NZ500 for it at the time (about 2-3 yrs ago) so they're probably much cheaper by now. Undoubtedly there will be other models available as well. We can scan in 4 slides each time and have control over the quality. I'm in the process of scanning in literally 100's of slides taken over the years.

[OGD] Dend. brymerianum
Hi everyone, I'm looking for information on the culture of Dend. brymerianum. I understand it is an intermediate/cool growing species, approx medium to medium-high light levels, but that's all I know. What moisture requirements does the species have and does it have a pronounced dormant period? Any tips will be appreciated. Thanks, Julia ___ the OrchidGuide Digest (OGD) orchids@orchidguide.com http://orchidguide.com/mailman/listinfo/orchids_orchidguide.com
[OGD] Pods to flask
I have 3 green pods well under way to ripening. The plants, mainly minicatts, are presently on a windowsill with 3 hours direct sun a day.
