BTZS ExpoDev for iOS is now available in the iTunes store

[Laura_Campbell]

I know that but, what's the connection been the book and this app?

From David Jades' website: http://tinyoctopus.net/ExpoDev/

"BTZS ExpoDev is the newest generation of ExpoDev for Apple iOS devices. As a companion app for BTZS Plotter, ExpoDev allows you to use your BTZS Film Profiles to accurately calculate B&W film exposures in the field for consistently exposed negatives that are easier to print in the darkroom. ExpoDev was designed for Large Format film photographers working in any traditional or alternative process (including hybrid processes such as film scanning/digital printing)."

Overly complicated.

The connection between this app and the book is, I worked with Phil Davis (book author) for a number of years creating the supporting software for the BTZS methodology. I am the author of Plotter for Windows, worked on upgrades to the existing Palm version of ExpoDev, and created the PocketPC and now iOS versions of ExpoDev. I also created and run the web site, http://BTZS.org.

I'm not sure if you're reacting to what I wrote as part of a blog article as too complicated or the app itself. If the app, I can assure you that a lot of thought and work was put into this app the make it as quick and convenient as possible.

I have the program on a palm, which is small and a pain to use with the little plastic pen. I think I will purchase an ipod and this app. Can I get one of the cheaper 2nd gen ipods or do I need the newer version? Also, is it simple transferring my test data from my pc to the ipod?

Thanks

coops: the listed compatibility with iPods is
• iPod touch (4th generation)
• iPod touch (3rd generation)

so you need one of the touch screen models. i.e. the iPod Touch (which is really just an iPhone without the cellular radio).

Looks kinda interesting but the price is way to high to consider testing it out. I've tried other iOS apps for keeping track of exposures and could not find one I liked. They were all just a few bucks so no biggie but $25 is way to much to spend for an app like that.

Unlike many other apps, this isn't something to install and try out. It isn't a standalone app.

It doesn't just track exposure data, it performs calculations that take a number of factors into consideration, even the contrast paper you're planning to print on (or not). It determines exposure and development.

You need test data - about your film and more - and the (separate) application which creates it, in order to use this application.

The price is very reasonable IMHO. It's a specialized tool.

And I think they did a very nice job with the interface.

You need test data - about your film and more - and the (separate) application which creates it, in order to even use this application.

The price is very reasonable IMHO. It's a specialized tool.

Ken is absolutely right, and I also agree the price is very reasonable.

I agree with Ken as well. This app is totally unique and is unlike the generic apps currently available. When I consider how much we spend on equipment, film, and other photographic supplies, the price of this app is inexpensive by comparison. I use ExpoDev on an iPod Touch and love it. Thank you to David Jade for investing so many months (7 +) to create this wonderful tool.

What is this seperate application.
I thought I would give it a try but the app has a note stating you cannot use the app without BTZS film profiles exported by the BTZS plotter application.
I could not find any other BTZS app.
