Android app for Reciprocity Failure calculation

[hoganlia]

Hi folks, I came across a video (two years old) by Kyle McDougall where he mentioned an app for both IOS and Android called Reciprocity Timer which looked very interesting. Sadly that doesn't seem to be available in Android any more. I can get my head around the concept of Reciprocity Failure but I don't trust my mathematical ability to calculate the adjustments I need correctly myself. An app would be a very big help. Any ideas?
Thanks in advance

Many thanks to the moderator who relocated my originally misplaced post.

Much obliged.

No problem; I hope someone will come along with the answer to your question, soon!
Unfortunately, I don't use such apps a lot, so I can't offer much in the way of useful advice.

Check out the Android app called Exposure Assistant. I haven't used it myself but it has received good reviews. You can also check out the manufacturer's data sheet for the film you're using, which often includes reciprocity compensation data/formulas.

Many thanks for the information. I'll check it out and let you know what I think.

I use an app called light meter ,
Its a light meter yes, but has a bunch of other stuff.

Generally the info given by the manufacturer of the film is good enough. Shooting time exposures usually requires some guest work besides just the reciprocity.

Thanks so much to all. I think both of these apps can help me, Light Meter looks very complete.

As for getting info off the product sheet, I am aware of that but I will have to find out how to do the math. One of my weaker skills!
