Can you explain to me, then, how they got the reflection of the camera in the
bird's eye?

I went back to see what you were talking about and decided to just look
in wonder at the pictures of the tiny, trusting, got the world in
control little birds. Would that AI had the faith and the trust to take
what is offered and be thankful.

I still have not figured out for sure where the pictures were taken -- I
don recognize the little birds at all, They don't look like what I
remember from southern California and I don't think I ever saw any in
Central California.

The Jays are Steller's Jays are definitely high altitude, but I learned
yesterday the are all over then Sierra Nevada and the Rockies way up
into Southeast.

Just in case it is necessary.....

I started this thread with a pointer to another article about a goofy
helmet designed to lure humming birds close enough to see and photograph
up close and personal (that would make a catchy come-on, wouldn't it?).

My point, the troll not withstanding, is and was: you don't need all of
that nonsense, or any of it.

A little patience and peace and quiet are all you need.

I've not had a Hummingbird land on me that I know of, but I haven't
tried very hard.

I have had them approach close enough to feel the breeze from their
wings, either when they were trying to intimidate me, or when they were
trying to work out what I was doing with their syrup feeders.

I have had Scrub Jays take peanuts out of my hand, and stand on my hand
when I didn't let go.

I have had Chipmunks and Golden Mantle squirrels run up my legs to my
shoulders, I have seen the ordinary squirrels we have here (I don't
know what the names are) come to the sound of jingled keys and search my
pockets for nuts.

It really is possible to make friends with the critters, if you give
them a chance and you don't need any high-tech trickery to make it look
like it happened.

I'm out of this thread.

I have no doubt that each image was taken outdoors, so that is an actual
picture of the hummingbird, yes. However, it was probably taken while
sitting on a twig or even a feeder against either a blue or green
background. Then a separate image of the finger was taken followed by a
separate image of the background, again all outdoors and under the same
lighting. Maintaining a blue/ green background in the case of the bird/
finger made the later recombining job all too easy.

Don't take my word for it. Motion picture artists do this all the time, but
it's a bit more difficult because for film the foreground subject and blue
screen lighting have to be just right at the right times. With photos the
job is much easier and doable. There is all sorts of info around the web
these days on blue/ green chroma screen work.

Well, Larry, that was one of the reasons I decided to reply to this thread.
I thought by "silliness" you meant something suspicious. I often "troll"
here, I guess- whatever you want to call it- and read the threads without
comment. When you mentioned the adjective and the image, I felt some
commentary was necessary. Do you folks want to be informed of possible
drastic image manipulation these days, using digital technology, or take
them as they are? If you choose the latter, that's fine, but I think to
call something a genuine image (image implying being taken with a digital
camera) is a stretch. Artful, yes, but real- maybe, maybe not.

I won't respond further here since my response has apparently created some
dissention in the ranks, but I can't promise not to respond in the future
when seeing what I feel could be questionable imagery. Isn't it better not
to be fooled by eight year old trickery (yes, 8 year olds can combine images
into whatever they like) then to be embarrased by it?

Good day and farewell to this thread,
Drake

These pontifications get more and more silly all the time. None of the
photos show any sign of cloning or combining of multiple images. "Drake"
probably doesn't even own a copy of Photoshop or know how to do what he
claims was done to these images. If he did know how to do those things,
he would easily be able to tell that it hasn't been done to these photos.

Two of the linked images (the first two) show the use some selective
manipulation of levels to create a false vignette (darkening of the
periphery of the images) but little more. The rest of the images have no
significant manipulation.

Seriously, Drake, show us a picture. Anything. Do you even own a camera?

Eric, you are the one who needs to visit basic image repocessing technique.
Once you have studied such techniques and are prepared for intelligent
conversation instead of sabre rattling, then we'll talk. I'm out of this

Now that you've explained the reflection of the camera, perhaps you can
explain
the natural position of the bird's toes, and their shadow on the person's
finger.

That's another easy task for Photoshop. Some folks specialize in shadow
creation and detail, not a difficult task at all.

For every explanation you come up with, I'm quite prepared to pose another
question about some aspect of the photograph.

As you wish, but keep in mind that Photoshop has become advanced enough,
especially over the last couple of years, to make anything digital very easy
to manipulate even for kids.

Photoshop for Kids? Now we know you do not use Photoshop.

There are so many small details in the photo that to me say it's real,

have to ask, why would someone go to such painstaking effort to Photoshop
it
just to stick it up on a website?

If it was a child or a teen looking for attention, he/ she has got it for
sure. Plus, they can show it off to friends and so forth.

For the kind of work you're claiming these photos to contain, I would
expect to
see them in advertisements or expensive books of photography, not shared
freely
at pixdaus or other sites.

Kids create stuff all the time, seemingly complex, but shared around the
world for no profit just for attention. I keep mentioning Photoshop, but
there are a good many other applications up to the task as well and there
are so many plug-ins that it's easy to lose track of them all.

Halloween. We
could see the weather map wherever he placed the file folder. Made for a

when he put it over his tummy and we could see right through him.

Here, let me send you a green file folder. Or perhaps you work with blue
screen.
No matter, I'll send you a blue one too.

Not necessary, I'm well aware of blue/ green screen work. In fact, such
technique forms the basis for most motion picture work today, especially
sci-fi. The classic example, of course, is when actors are driving a car.
Hollywood used to replace the blue screen with moving film frame-by-frame
during the pre-digital era, but this is no longer the case, and a person
with only moderate program familiarity can pretty easily do it at home too.
And with still imagery the task is elementary.

That is wrong more ways than the last troll was.

I'm really sorry I posted those picture-pointers.

I'm not trying to take a stab at the messenger here (it's not your fault
for criticisms beyond your control), but your comment begs the question
"why"? Would you want a flashbulb directly in the face or to be captured,
poked or proded? Don't think anyone would, least of all the

No, and no. But it happens anyway. But as I put you in the troll filter,
note that most of the pictures do not use flash.

And some of the birds get caught in the same traps, looking for the free
lunch.

Probably a lesson there somewhere.


(There are a number of things about our interface with that nature that
bother me, and have bothered me since before it was a political
correctness plaything. Just this week, I think it was, I complained about
the opinion some folks have that until you have looked at a bird over the
sights of a shotgun, you can't possible know if it is extinct or not. But
this is not the forum for that discussion.

And just for the record, I personally think the kinds of interventions you
whine about are responsible for the saving some of the critters from
extinction.)

I said it before, this time I will filter the thread name--I'm out. The
Turkeys (a reintroduction issue, I think) are looking for their free
lunch.

Okay, I'll bite. Just what do you think all those banders are thinking

be recapturing banded birds multiple times in the same location. Do you
think that once the hummingbird dies from the shock of the initial
capture that the bands are then traded among birds as prized possessions
so that they can fool the banders into thinking that the same bird is

To be honest, I don't understand the purpose of banding. What benefit does
mankind gain from such an activity other than to possibly cause harm to the
birds? Also, some of the photos out there of captured/ sedated/ banded
birds doesn't look too kindly regarding bird health.

If I decided to expose you to a bunch of radiation where you had no choice

leukemia in the long term. Going by your line of thinking, everyone else

You don't know the purpose so you assume there is none. We can't protect
bird's habitats without knowing how and when you use them. Banding is
important for determining migration patterns and survival rates. If you
subscribe to the notion that ignorance is bliss, you might be very
happy. I believe (to cough up another cliche) that knowledge is power.

Are you sure about that? What has your total radiation exposure been? What
percentage of your x-rays have been "hard"/ "soft" and what frequency/
intensity? Without knowing this data, it's difficult to say what, if any,
your long term health effects will be. Radiation exposure is cumulative, so
small amounts add up over time.

I'll take you at your word, and explain:

First, birds are not sedated for banding. Once captured, most of them
relax once they figure out struggling isn't productive, and just wait
more-or-less patiently for release. However, birds have individual
personalities (for want of a better term), and a few remain squirmy.
Banders are taught to monitor their subjects constantly for signs of
stress, and stressed birds are released immediately, whether or not
they've been banded. So are birds that don't settle down, if there's the
least concern about them hurting themselves. We recognize that capture
is potentially stressful for the bird, and banding is only authorized to
gather raw data for bona fide research, and only if the benefit to the
species outweighs the risk to the individual.

Of course, banders are also taught how to capture, handle, and restrain
birds without injury. They also pledge to follow a written code of
ethics. The welfare of the bird always comes first, and any bander who
violates this first principle will lose his permit. Banding is learned
through apprenticeship, and attitude is far more important than skill to
the successful completion of training.

The benefit isn't to mankind, except to help us be better stewards of
nature--the goal of bird banding is conservation. To study a species'
population, one must study individuals then aggregate the data over both
geography and time. Without data that illuminates population trends, we
cannot know how habitat changes and other factors affect each species.
Aside from just counting birds, banding is the basic (usually the only)
tool to track individuals as they migrate, so we can correlate breeding
and wintering ranges; routine examination and measurements also tell us
about each bird's health.

I am a licensed master hummingbird bander. In my ten years' experience,
most birds fly away as soon as I release them. A few take several
seconds to reorient themselves before leaving. I've only had to release
two birds prematurely due to concern about their levels of stress. Any
hummingbird held captive for more than a couple of minutes is offered a
chance to feed before release. Most of the birds I band at my home are
back at the same feeder the next day, and some fly back into my trap
within minutes, despite plenty of other feeders in my neighborhood. I
have never injured a bird, nor had one die due to capture or handling.

Keep in mind, if the birds didn't return in good health to be recaptured
(so the band can be read), banding would be utterly useless as a
scientific tool and permits would never be issued.
