Animal Kingdom / Re: Show your Bird Portraits

Wow - there are some truly amazing photos in this thread..if you like to shoot birds but are not familiar with their name (proper or otherwise) try using http://www.whatbird.com it has an excellent built in wizard

Here's a few I shot over the past 6 months - all photos shot in the wild - no zoo or otherwise with 7D + 400mm hand held:

Belted Kingfisher (difficult to capture..you get anywhere near these birds they fly about 100 yards away.  You go that direction they revert back to original starting point.  I had to creep up and hide to nab this one..oh the fun!

I used this review to acquire my UV's...note the Hoya HMC UV came in first and about half the cost of the B&Wand no degradation on the final photo.  Tiffens' ranked dead last.

The best service and prices in the US on these are through Event Cameras on Ebay.  Ask for Ben - the guy knows his stuff and responds to all emails.  If you need a polarizer the same site offers Marumi DHG Super as second place along with with B&W which was the highest rated (both very close)

I am skeptical of this type of cleaning..anyone?

This might be a joke though note all the comments - I don't buy that cleaning method. Just what we need are hard water stains on the mirror for starters. Then there's the rust / corrosion factor.  Being in IT, I've opened PC's near homes on the beach and they were rusted with corrosion inside.

re:  Quasimodo - not sure if you found my link here in the forum but for convenience here it tis:
http://www.canonrumors.com/forum/index.php/topic,3159.0.html this clearly shows examples of the higher quality ND fader such as the one by Light Craft and their latest 82mm 2-10 stopper.

I returned this higher quality fader as I was most disappointed in many aspects.  I ultimately went with a B&W 10 stopper as Neuro has suggested as well as a ND64 Pro hoya 6 stopper.  I found them to be more consistent and reliable and no vignetting issues though I do have a cropped EOS 7D sensor.  If you have a concern about vignetting I can tell you the Hoya ND64 has a 3mm surface ring vs. some of the competitive 5mm ones out in the market place.  That might be one feature to shop for during your quest.

As mentioned everyone has their personal opinion on these filters and brands.  I've learned recently that even a high quality filter can present issues.  Recently I had thought to get the Light Craft Fader that claimed to offer 2-10 stops as a variable ND (their newest HD series).  In my opinion this was a gross exaggeration. I posted a few test shows in the lens forum for the 16-35 mkii lens in comparison to a Hoya ND400 9 stop filter on a 72mm lens since Hoya doesn't make this filter for an 82mm.  The Fader couldn't touch the uniformity nor the 9 stop range of the Hoya ND400 so the fader went back.  I replaced it with a B&W 82mm 10 stopper and a Hoya HD Pro ND64 (6 stopper).  As the author above me writes..dont' go cheap.  They are correct.do your research.  I do stick with specific Hoya & Marumi's and B&W..I've never had an issue.  To further illustrate check out this UV filter review..note the winner and how Tiffen's were dead last in degrading the final image and note how a specific "cheaper" Hoya beat out a more expensive Hoya in the results (note I didn't say "cheap" I said "cheaper" http://www.lenstip.com/113.1-article-UV_filters_test.html note line #4 for the summary.

Wow.  Innavigable just got redefined.  That site have an index?

That site needs a bit of help.  I research elsewhere then call their 800 to see if they have it.  Excellent top notch service however.

Another way to put it is that the cyclist occupies a given area of the frame for only say 1/20th of a second. The rest of the exposure (2.95 seconds) is filled by only the background. And since both the background and the cyclist are illuminated by the same light and nothing more, the background wins.

David that was very well stated. I did a 3 second exposure (not posted) but the cyclist was nowhere to be found (as Neuro suggests) it was as if I taken a photo with no one in it.  Indeed "the background wins".  Seems this whole project is hindering on a much brighter light source against a darker background to create such a trail or as Gryphon mentioned an injection of bikers for the whole 3 seconds or reverting to a panning scenario.

tt  - when you reference strobe I believe you are suggesting using the multi flash feature?  that's actually a cool idea with the flash light..never thought of that one.

The effect you've 'discovered' is the main reason I have 10-stop ND filters - shooting architecture.  Interesting architecture is often found in urban settings with lots of foot traffic, or the architecture itself is a tourist attraction with lots of bystanders.  The long exposures with a 10-stop ND effectively blur out/eliminate pedestrians, passing cars, etc.
- yes indeed I bumped into this effect by accident and a great idea for different uses of the 10 stopper.

Gryphon, first thanks for all the assistance.  Just to be clear my statement of the ND eliminating daylight was merely an abridged summary of
Quote
it's enabling you to use a longer shutter speed than would otherwise be possible, on a bright day even using ISO100 and f/22 you might still be getting 1/4 for a correct exposure which wouldn't be enough to blur running water..

The water example I provided was at  F32, ISO 100 and 1/3s not far off from what was deemed as not enough to blur running water

In either case, it seems it all boils down to the contrast of ambient light and/or injection of a constant flow of new subjects into he same scene.

(Neuro - I just got the 82mm 10 stopper yesterday - thanks for that great suggestion just waiting to use it.)

The example I mention with the headlights at night was merely to define an example.  Sorry if I didn't clearly state, I was looking to achieve a similar effect under a different set of circumstances and believe it is possible

Perhaps I can re-emphasize as I've realized in essence I (may) already be doing this.  Let's take water flow during daylight we've all seen this before (example attached to be clear).  We all know we can get that nice blur with an ND in eliminating daylight, I'm trying to achieve the same effect with a cyclist as in this example I have shot.  Night vs. day doesn't seem to matter.  It would seem a)speed of subject and b)length of subject would be key factors I believe.  Open to additional thoughts or putting me back on the right track in case I am now off course :)

Revup: You eventually get used to it after a couple outings of hurting arms, but just remember, always lift the lens, not the camera.  It'll rip the mount right out of the body if you let it dangle.
So true...  After a short while I got used to the 400mm (5.6 though)..it was an initial shocker but as you say you get used to it.  When mounted, I always grab it by the neck.

EOS Bodies - For Stills / Image effects with EOS 7D possible ?

While on a heavily shaded dirt hiking path the other day, I loaded my 15-85mm on the 7D with a tripod and had approximately 60 feet of dirt trail in the view finder at 18mm.   I was attempting to create a "blurred trailing effect" from a cyclist but failed.  Much like a stream of car lights at night when you slow the shutter speed down.  I was using a nine stop Hoya ND400 filter with the lens and had the lens open for about 3 seconds.  The exposure was decent despite the heavy contrast however the cyclist didn't appear in the image as he rode the 60 feet of trail.  It was as if the event never happened.  I finally got another cyclist after shortening the shutter speed to about 1/10th (see attached image) but he was a short blur within the 70 feet and not the effect I was aiming for.

Perhaps this is not do able in shaded daylight but if anyone has any ideas that would be great.  Perhaps my 580 EX II using multi flash would resolve this?  Open to any thoughts, this is new ground for me.

Interesting to find this topic..just found a "blue flower" (Plumbago auriculata) the other day - taken with 100mm 2.8 L Macro lens just before dark (tripod)

at least you can return it, let us know how you go with the search for a replacement
it seems to be the superzoom of variable ND's
i wonder if the dark end offering is any better the 9 to 12 stop one

OK here's what I decided and did get a full refund of $320:  I acquired the Marumi Super DHG Polarizer $100, the Hoya ND64 HD Pro Digital ($80) and I bit the big bullet today and bought (Per Neuro's recommendation) the B&W 10 Stopper for $226 through filterconnection.  Andrea there is such a pleasant individual to work with.  Just prior I had bought the Cokin graduation P121 Series (L,S,M) plus a ring adapter and holder.  She offered to take them back and offer a credit of 95% of the purchase price toward toward the 10 stopper..how could I refuse..those Cokins were a bit disappointing anyway with the purple hue when stacking more than one.  I've lost my only set of graduated but gained a set of great ND's..I think it was worth the swap.  Staying away from the Fader types then across the board..just not for my taste and also hiding my wallet :)
