iPhone Photo Apps

There has been a fair amount of discussion about photo related apps for Iphone. I have been using PhotoJot, it records your gps position, shows it on a map, allows 4 snapshots, exposure info, flash info, ev info, notes and voice annotation. They are promising a DOF calculator in an upcoming version.It shows a thumbnail of each Jot on the start page and there is a planner.I use it to remember where to go photograph by perusing the Jot library and making event alerts on the Iphone calendar. I have no ties to this other than it's use.....Evan Clarke

I just downloaded the Massive Development Chart for my iPod Touch (same deal with iPhone)...it's great!

Even can be used as a countdown timer, and you can tweak the times to what works for you. It's a real treat.

The timer function looks great.

Along the line of the Johnson Exposure calculator, the Black Cat Extended exposure calculator has some other useful data along with it. The nice thing about this type of app is that it would work for the Ipod Touch as well as the IPhone. The Black Cat calculator is also good for pinhole.

"Daylight" is a free app that gives you the dawn, dusk, sunrise, and sunset times at your present location on any date. Unfortunately it doesn't let you plug in alternate locations, but it's handy if you want to know how much light you've got left.

"The Massive Dev. Chart" app was just updated and has improvements like more options for agitation schemes and easier customization.

"iHandy Level" is another free app I use for leveling tripods, measuring tilt angles, and such.

Anyone using an app called "pCAM"? It looks interesting, but at around $30 it's on the pricey side for an iPhone app. It does a wide range of calculations useful for still and motion picture photography for a wide range of film, digital, and cine formats, like DOF, hyperfocal, field of view, exposure calculations, color filtration, and other things.

I don't know if it does this or if this exists, but something really useful would be an iPhone app that can function as a color temperature meter. It seems you should be able to put a diffuser over the lens to take an incident color temperature reading and have software that can calculate the filtration required for the desired white balance (daylight/tungsten), or maybe it could work by taking a reflected reading from a grey card or a white object where you tap the reference object on the screen and get the fitration to make it neutral with a given emulsion entered separately.

Okay, after doing a little more research, but not finding user reviews particularly, I shelled out the $30 for pCAM, and it's a fairly sophisticated and handy looking app, ported from the Palm operating system, aimed mainly at cinematographers, but with many useful features for still photographers. These include a couple of DOF/hyperfocal calculators, a field of view calculator, approximate focal length equivalents for two different formats, a calculator that lets you plug in the color temperature of the light source, and it gives you the correction filter needed for tungsten or daylight film, a calculator for diopter closeup lenses, macro calculator, underwater distance calculator, light coverage calculator, mired shift calculator, various useful conversions, Siemens star focus target (very handy, I'd think--put your phone in the scene at night to focus), and a slate that might prove handy for stills as well as motion pictures, plus various other calculations specific to motion picture photography.

The diagrams showing what is being calculated are clear, and it is a well thought out program.
