Greetings to all you digital photo experts,
I have just taken several photos of longipes 'Katsuragawa Beni', and
while observing the photos, I have noticed:
**when the photo is shown at 50% size, the veins are red all the way out
to the end of the leaves and the base of the leaf is very red;
** at 75% size, the red is more concentrated in the veins, less scattered
and heavy in the base of the leaf; and
** at 100% photo size, the red is visible up 1/3 of the way into the base
of the leaf, but not visible in the veins the rest of the way to the leaf
The 100% size is similar to when the necked eye observes the plant. Now
does this means that the red is there, but becomes observable only when
the pixels become more concentrated at 50%, making the red show up
better? Better take Jim Wilkins' class at Hosta College - 3 weeks away!.
Would welcome explanations??? Kevin and Jim?

unbiased-opinion; and of course I am NO-EXPERT on this. TODAY I SHALL BE

Further to what Altara already wrote you, I would like to respond directly
on your question: as to whether or not photographs are lying on their
coloring, (an "optical illusion!..or NOT?" as Altara put it?); and for the
sake of discussion alone?
LET'S LOOK AT THIS FROM A DIFFERENT PERSPECTIVE; that is to say, blowing up
a photo'graph into a larger-size? We know that, a new larger-sized digital
pixels DIGI-PIX: become more and more pixilated (more distorted and out of
focus?) with each size increase which we do -- right?
I am going to take the position THAT I HONESTLY BELIEVE:
-- If you see the red-coloring moving into the leaf-veining; and this
extends to the very tips of leaves (as was the case in your 50%
photo-example?) THEN THIS IS "A MORE TRUE IMAGE" than the 75% and 100%
blow-ups you are comparing to? Suggesting to me, that the red-color is
definitely present, in the gene-pool factors of Katsuragawa?
<subnote> I would also like to suggest, that the red-coloring of this
cultivar: is present in leaf-cell-tissue likewise, having studied many
digitals via computer. And most particularly, in those
digital-image-samples, which you have shown me?
-- When you double the size of an image; which is like your (50% verses
100% examples?), the image-resolution-quality (per
pixel-complexity/application?) within the photo, becomes more and more
pixilated, by every size-expansion done? This happens every time you save
a digital image (using the JPEG-format particularly?); and this happens
via, THE IMAGE COMPRESSION FACTORS WITHIN "filename.jpg" (JPEG-imaging
formats) on every save to disk function.
*NOW LET'S BRING TO MIND SOME SPECIAL IMAGE CREATOR SPECIALISTS...shall we?*
Bill Meyer, whom created the 'Hosta
Color-Wheel' http://www.hostasports.com/color_wheel.htm for the 'Sports
Committe': is probably the most knowledgeable person we have, pertaining to
this coloring-topic you question?
I've seen e-mails on yahoogroups.com/hostapix; wherein Bill Meyer has tried
to educate those of us fooling around with digital-imaging; and I'm going
to mention some of his most advanced suggestions related to the best way to
do digital-color-imaging (a very complex Topic, due to many factors in play?).
Will's BEST ADVICE, and Bob Axmear also advised us on this (creator of The
Internet Hosta Library [ www.hostalibrary.org ] -- they have emphasized
this point many times over, trying to teach everyone how to make good
<subnote> What the above is leaning into is: how to do 'TRUE-IMAGING' on
computer (and I will simply call this ("VIRTUAL-REALITY in the making of
your digi-pix!"), for lack of better wording.
THE POINT HERE
To avoid the severe-digital-image-pixilation (distortion of pixels within
an image?) I.E.. pixel-compression done in saving of an image, say in
"filename.jpg" format; THERE ARE SEVERAL WAYS TO HAVE THIS NOT HAPPEN:
1) Do not save any images *using compression of image-sizes* (jpeg) while
you are doing the initial setups (draft-up modes?), of your digi-pix
creation? If you prefer to use JPEG, then use the "Save As" button (not
Save?) function, and this allows you to select no compression at all. OR
Use imaging formats, that do no compression at all (like microsoft bitmap
"filename.bmp") or "filename.tif" (TIF format?).
Please keep in mind, that:
-- making high resolution (Virtual Reality Published Pictures?) is
too-complex for me to get into here;
-- most scanners, are doing true-imaging in 16 million colors; and digital
cameras are probably more precise?
-- Digi-Pix being made mostly for Internet-use/Group-sharing, are usually
done to take advantage of such things as *disk-size/speed-of-loading*
hence, these are not usually made at a (1200 dots-per-inch, or highter?)
pixel-resolution, as is done in printing/publishing. This means, all
digital pix done in true-imaging (highest quality possible?); WITH NO
COMPRESSION BEING DONE AT SAVING TO DISK: are going to be many mega bytes
by file-size; and therefore, they cannot be saved to floppy disks. A super
fast-speed computer will also be required to edit, save and move these kind
of files around. As an example, an 8" by 10" digital-image print-setup,
might be 100,000,000 bytes (100 million bytes by it's file-size = one
Just a few personal thoughts here Charlie, and I'm thinking, that all you
have to do to prove my rhetoric-ramblings above...
>>--- and suggesting RED IS THERE!---> you will see this, if you have
digital-images done at the highest-resolution-possible; and of course, when
you save these to disk, USE AN IMAGING-FORMAT HAVING *NO COMPRESSION
FACTORS AT ALL*..IN PLAY? And excuse me please CHAS? -- I am not
suggesting in the least -- that you don't know how to make good digial
just a few thoughts and hope this helps <<sumpin?>>
