Posted at 21:45h, 09 OctoberIt looks awesome. My biggest problem using these types of apps are my ability to judge the distance of the subject I’m shooting. How can I be exact in knowing the distance of my subject?

Posted at 21:59h, 09 OctoberThanks Mark!
Some lenses have the feet and meters scale in a little window, which can be very helpful, but if that’s not available a guestimate is really all that’s necessary. I just guess roughly how far my main subject is, or when using Hyperfocal Distance, just guess approximate how far out that point will be.
I find my DoF calc more useful for understanding approximately how much depth of field I’m going to get, rather than looking for exact distances and depth.
Of course, for closer distances, you can measure from the sensor, but I have rarely done that. Again, these numbers are more a guide for aligning the thought process than anything else.
I hope that helps some.
Regards,
Martin.

Posted at 23:02h, 09 OctoberThanks Martin for the reply. I redoaded the app and I must say it’s impressive. It can really help you learn more about shooting and learning what is the DOF using any lens and apature. I’ve been playing with it and thinking how this is going to help with my photography. I must say also THANK YOU for the free upgrade. You must be very proud of the new app.
