How To Measure?

Posted by oregonwoodsmoke 5 OR Sunset 1A (My Page) on

I've got some nice NOIDs that I would love to submit to see if anyone can identify them.

I would like to know where to measure to in order to get the height, and what angles for the photos?

Nothing is up yet, so no photos yet.

I've got a black that is really black and stays black, so I am hoping that is unusual enough that someone can identify it. All my other blacks turn purple fairly soon after blooming, so I am hoping that the persistent black will be less common.

Interesting you should ask- there is a whole series of posts up on the American Iris Society blog on iris height and bloom period. They measure from the top of the rhizome to the top of the flower.

The height question will be coming up soon- I'll post it here.

Set your camera at the highest resolution! TIFF is great -- when you resize for posting it will be a better image.

Do not shoot in the shade or on a dark day. Check color in the camera's viewing screen (brain dead on name of this) -- what you see is verry close to what you get. Morning sun is usually better. Late afternoon sun tends to emphasize certain pigments which makes for a gorgeous inaccurate photo. Stay clear of raindrops for ID purposes.

Take a side view about even with the bloom.

Also a side view with one fall facing you (zoom in just a bit to minimize parallax (sp. ?) (barrel distortion).

A shot downwards at a 45 degree angle that will show the haft area and beard.

What else ??? An entire stalk shot is valuable as branching can be a help. Height can vary from year to year. Oh, lots of shots at various times of day. You'll find what works best in your area.

Looking forward to seeing your iris!
