How far away is your subject? (1 Viewer)

How far away is your subject? And how can you tell?

I know that "the tree just beyond the path over the fence" is medium far, and "the reeds at the corner of the pond" is further - - but have no idea whether that tree is more like 50 or 100 metres - - etc . Walking to it in a straight line, dragging a tape measure, would be a pretty messy process.

What distances do you find suitable for really good shots, as opposed to identifiable but non-artistic shots?

In my limited experience, good shots regularly at up to 10 meters , so-so 15-30 meters, but I usually digiscope small birds, so bigger birds can be OK at longer distances. The picture of the hawk was shot at ~75meters. You can calculate distance using The digiscope calculator provided by J. Turberville at

Hope this helps. Jose

Interesting calculator, but I certainly don't know enough to be able to use it. Rather than figure out my Bayer Mask and my Rayleigh factors, I might as well just measure some standard distances and build my own custom calibration system.

a BIG pace when striding out is roughly 1 meter. So get out there and stride the distance to the tree in question. You will then be able 'guestimate' other distances.

As below I think you can ds at any length given the correct light and patience...

Reed bunting 3 metres. King fisher 150 metres

If you go to Google Earth you can use their Measure Feature to measure the distance between two points. I've used it down to 25 metres from a restaurant that I digiscope from to a rock in the harbour. They both show up on Google Earth. Neil.
ps 70 metres is about as far as you can go and show any detail , after that it is just for id/record purposes.

Brilliant.

(unfortunately I can't use it as my street, house, fence, and even pond did not exist 3 yrs ago and their satellite images are 3+ years old. Still - - eventually they'll update and your idea will work)

Brilliant.... satellite images are 3+ years old. .

Mapquest.com has a fresher satellite image, which I was able to graft on top of the google image, so now I can measure all my backyard sightings. Amazing.

Hi

Just a thought and I havn't a clue if this would work as I'm not a golfer, but would these golf "thingies" which measure the distance from ball to flag be any good - I'll leave it to the golfers out there to reply!

Cheers

Stuart

I know for sure that one particular type wont work because you have to sight the top and bottom of the flag to get a measurement. Not sure about some of the later ones.
But you can buy Ultrasonic distance tapes that work to a degree, not overly accurate but close enough. Ernie
