UpStrap QR on a K100D
Posted By CDP

I've been thinking about replacing the stock neck strap on my K100D with one that has quick release locks. The current strap is a pain when I have the camera on a tripod. The UpStrap gets very good reviews but I haven't been able to find any info on the thickness of the strap that goes through the camera lugs. So the question is has anyone used the the UpStrap QR on their K100D or K110D and, if so, how has it worked for you?

I just bought one of these today so I'm claiming no expertise at all. I did watch the videos demonstrating how to use the card. The one point that is stressed is to have the card in the same light as the subject. Looking at the original image it's apparent that the card is oriented so it is in the shadow of the card. Wouldn't that effect how the software calculates the WB? The colors in the original seem closer to the colors I'd expect to see in a scene like that but the ones that have been "balanced" seem over-saturated to me. I think I'd try placing the card on the ground so it is getting the same color light as the rest of the scene. Just a thought ...

I recently bought a waterproof nylon camera cover for my K100D from a company called FotoSharp. Haven't had it out yet but it looks like it'll do a good job keeping the camera dry. I've included a link ...

You can make stereo images using a DSLR even if that 3D adapter won't work correctly. Hinckc had the right idea using the base-plate of his tripod and displacing the camera from side-to-side. There is a device called a parallax bar (also called a slide bar) that mounts on a tripod with the camera attached. The part the has the camera attached is a rail that lets you displace the camera from side-to-side for the two shots used to make the stereo-pair. For landscapes you'd use a lot of displacement, for close-up work just a little. Here's a stereo-pair using a parallax bar. The displacement was only about 1/2 inch, a larger displacement would cause the image to look distorted when view.

This uses the crossed-eyes method.

Trying to eyeball the camera into the horizontal this way doesn't work well, at least in my experience. You may want to try one of those little bubble levels that fit into the hot-shoe. Here's an example that's currently on E-Bay.

Finally bit the bullet and bought a good tripod. It's the Manfrotto 3021BPro with a 322RC2 Ball Head. I plan on using the tripod much more than I have in the past. I'm concerned that taking the QR plate on and off a lot may, over time, mangle the threads on the camera. Any problems with just leaving the plate on the camera permanently?

I was able to get some addition URLs for this company through Google. The translation of the product page by Google is as follows:

* Makeall length grip JC-1.

This length grip came to make for Pentax dslr K-100D users.

There is not an additional battery and a dial and a [su] trap ring and only it is a simple grip which is the anti- only shutter and the shutter and the tripod mount socket. To refer to the lower part product photograph, against the product positively, after familiarizing, about under purchasing it gives and it wishes.

* Product price: 90.000 won (boat carriage 3,000 won inclusion)

From what I can gather:

Rose Festival Ships - Portland, OR

Thanks for the Rose Festival images. I lived in Portland for 25 years and remember well "the sailors swimming upstream to spawn". :D I worked in the Georgia-Pacific building (now Standard Insurance) and have a really good view of the waterfront area. Remember one time I keep getting this funny ringing sound from my WalkMan as I worked. It took a while till I realized that one of the Navy ships had a radar unit running and what I was hearing was the microwave beam painting the building as it revolved. Do they still have carnival rides down along the waterfront like they had in years past?

Thanks for the comments!

@Buddah Jones - I'm sending you an IM with a link to a .zip containing the 3 original PEF files. It's pretty large (25MG) but please do feel free to tinker as necessary. Let me know when you're done with the link so I can remove the file.

@Donald - Your comment on the cropping issue interested me. I tried several and none of them worked quite right. This one looked the best of the bunch but still doesn't satisfy. I'd like to see how you would have cropped the image if you'd care to show me.

Rewound the Leader Back Inside the Canister!

When I shot bulk film, I used a film changing bag for loading the film loader and such. They're very handy to have around just for situations like yours. You open the zipper, put what you want to work with inside, close the zipper and stick your arms up to the elbow in the cuffs. There is elastic around the cuffs and the material is like a rubberized cloth so it's light-tight. You can pop the end off the film cassette (if it's a standard 35mm cassette) with a bottle opener. If you do it carefully, it won't get bent up. Pull the spool out of the cassette, find the end of the leader, slip that through the slot in the cassette as you slide the spool back in the cassette. Snap the end back on and you're done. Here's a link as an example but you can probably find cheaper ones on E-Bay or Amazon.

I've seen something like this before called a thistledown velvet ant. It's actually a type of wasp and can sting pretty hard. It doesn't look quite right for that though.

I haven't used the pods you've asked about but I have been using the Ultra-pod II and find it very useful. I've attached a link that gives a rundown:

Ultra-pod II

Mostly I've used it with the strap attached to posts and hand-rails. It fits nicely in one of the side loops of my Lowepro 100 so goes everywhere with the camera bag.

BTW the link is to a forensics website. They just happen to have some of the better photos I've seen of using the Ultra-pod with the strap.
