On the subject of Power LEDs, i found a interesting poll on Facebook.  You can vote your favorite LED brand from Cree, Nichia, Seoul, Osram, Lumileds and the company promises to give us a discount for the wining brand. There is even a contest for the pages fans, the prize is a 400€ LED fixture, all you need to do to participate is to sign in your email, name and country!

The facebook page is facebook.com/LedRise and after looking at their shop i can see they already have kick ass prices. I cant wait for my favorite brand to win so i can buy the LEDs even cheaper! Come on , lets go vote, 100 votes are needed to decide the winner.

For illuminating macro shots, there are "ring lights" -- and I've seen instructions online for building them.  That's just a ring of LEDs mounted around the lens aimed at the close-up target distance.  Might be a project.

Don, Grand Rapids is not a bad guess on my location, I am 1hour south of Grand Rapids so I would only need to travel about 770 miles to Cree (hmm how to convince the wife this would be worthwhile).  I would expect something for luxury cars soon in forward lighting aka headlamps or driving lights. Car companies hate to spend money on development until someone else does it first than it is monkey see monkey do.

Regards 

I've made the drive between Grand Haven and Durham a couple of times now, easily done in a day, but still takes about 13 hours, which scarily is only 4 more hours than it took me to go from Grand Haven up to school at Michigan Tech.

Thanks for the pictures Foy.

Perhaps we should have an LED picture competition; who can take the coolest shots of LED’s?

Awesome pictures, unfortunately I cant find any pictures of XRE and XPE side by side, they look the same to me, but there is some difference in size or?

You can see the difference here on brted’s wiki:

The ring around the XR-E is square while round on the XP-E.

I posted these in the flashlight photography thread, but I thought they are appropriate here as well.

Alright, thanks!
So it looks like XR-E has huuuge metalic square around it while XP-E has nothing but the dome on top of it, nice, now I know that all my lights ar XP-E, because I cant see that giant square around LED in any of my lights :D!

Man, those make my sad pictures look stupid.  I still think I can get it right with the right lighting.

I think your pictures are more interesting. If you are going to do Macro... DO IT! The ones on CPF are clear but yours show "Life". A little better lighting and yours will lose the grain and be even more interesting. Nice! Thanks for sharing.

I simply cannot believe you with your “only available light so they’re grainy” stuff, oh please man you’re surrounded by lights!!! Fire one up and shoot away! lol Seriously, I use a Triple Nichia 219 on med mode to get my macro’s

If you don’t like the “hot spot” pull a reflector and use it as a mule, Wink

The one or two experiments I've tried to supplant available light with a flashlight looked horrible.  It seems the only pictures that turn out are when there is abundant, indirect light.  That was available in the kitchen of our last house from around noon to 6pm or so.  Good light never happens in this stupid house but the short wall on the side "yard" is perfect most of the time, except with the sun at high noon.

I really need to master macro using flash.

As this one was taken, low room light with a single Nichia 219 in a 2” keychain light running about 30 lumens. It’s also depicting a Nichia 219 in an OP reflector with Hi/Lo modes by VinhNguyen. I use a split 1 1/2” PVC pipe, drilled and tapped 1/4 × 20 to fit on a tripod. Mount that and use rubber bands to secure the light in the half-pipe so that I can direct the beam where I want it. Works beautifully. I now have a Triple Nichia 219 from EDC+ that is even better using the Med setting so that it can stay on for longer lengths of time without worry. Depending on how much depth-of-field I’m looking for, I might take 20 or more consecutive shots at 1:1 ratio .5mm apart.

This was taken with Canon’s 100mm Macro 2.8 L IS, 6 shots using a RRS macro rail to deepen the depth of field and stacked in CS5. Go ahead, left click on it then right click and select original in Flikr, see it at 100% from a 21MP full-frame sensor. Smile
