Reciprocity failure - another request!

Hi Guys - another request!

I was using the app with PAN-F in the Hasselblad a few days ago, down the coast, to get some nice seascapes, and the exposure time ran to about eight minutes with the 10-stop ND filter. Can you set the app to suspend the iPod auto-lock function to keep the screen and the sound alive while the timer is ticking? That would be a real help.

Other than that, I'm really enjoying the app and putting it to good use to help me get some great photos (when I manage to do my part right!). The reciprocity times for HP5 and PAN-F seem to be pretty close to spot-on.

Thanks again - cheers! Chris.

Paid app with restricted use.

No sure why this is an app you have to pay for to get restricted use of, only to find once you’ve paid that it’s going to cost another $15 for the app to work correctly and calculate correctly. Would be good if you could ad your focal length camera type film type etc to get a correct calculation but that is only in the pro version so ideally I’ve paid for a totally useless app that will only do what it specifies it will do if I’m prepared to pay more. I like a refund as I honestly feel ripped off!!

Not sure why this app doesn’t have more good reviews. Best app ever for anybody using film.
