This is a very cool implementation of a Raspberry Pi into a Battery Grip.  It basically puts a Linux computer right on the camera with a connection through the USB port. 

Since I would like to get to the point where I can add GPS coordinates into my photos as I take them, what do you think the chances are of attaching this device, having the photos go to the Raspberry Pi, adding in the GPS stream parsed into Lat and Long, and then writing the data back to the Compact Flash card?

The other things it can do would be nice too.

Third Party Manufacturers / Pelican Backpack
« on: September 24, 2012, 01:25:35 AM »

Well, Pelican has finally made a backpack, and it would fit my laptop in it perfectly...

Now the question is, could my camera fit in it, along with food and water for a few days.  (The camera would only be in the backpack when the food and water weren't) for traveling in the national parks.  Or clothes would be in the backpack if I were flying to someplace to vacation.

I might still need to use my nylon waterproof bag, but it does look like the bag would offer more protection thn any other bag I have seen.

I have a 50D camera that is about 3 years old that we abuse pretty good.  But recently it takes photos at 1/400 or 1/800th yet they are very washed out.   (Good photos and bad photos have the same EXIF data)  If you listen to the shutter it doesn't sound like the normal click.

Now, we are using a power supply for this camera, and I'm hoping that it is still getting enough power.  And if I unplug it and then plug it back in, it will act normally for a few photos.  I could try it on battery power.  And I'm using a center weighted average, so I think it should be able to get the exposure right in Av mode. 

Do you guys have any guesses as to what it is or something I could try?

Software & Accessories / Which external microphone for 5Dm2?
« on: February 09, 2012, 02:15:05 AM »,812.msg10498.html,2053.msg40879.html

This question has been asked before, but I am still trying to figure out which microphone will work for me.  My requirements are that it records in stereo, that it is small enough to travel, that it doesn't require any extra equipment or post-processing, has a furry wind screen for wind, and it would be nice if I could mount a LED light above it if it has a hot shoe mount on the top.

I will be taking video of national parks and other animals and landscapes for the most part.  And I am trying to keep it under $200, but $300 is the upper limit.

Canon has some, but do they only work with their video cameras?

These two:

Or their brand new one that comes out 4 days before I need it.

How directional is a shotgun microphone?  Should I go that route instead?
Is it stereo? 

Even Nikon has one that is designed to not need to use a battery, which I think is great.

Or this one is popular and a good size:

Maybe there are other choices out there that I haven't found.  Do you have any recommendations for microphones that just work?  Are there any settings in the camera to change when using an external microphone?

Canon General / Traveling internationally with lot of expensive gear?
« on: February 03, 2012, 12:27:36 AM »
Has anyone every had any problems with the customs people either going to or coming back from a country with thousands of dollars worth of camera gear?  Do I need a document saying that I have purchased this gear and will bring back the same gear?

Have you ever run into an airline that doesn't let you carry-on a Pelican 1510 case?

Everytime I try and figure out how to reduce the size and weight of gear I take, it just keeps getting bigger... 

Add to that, I won't have my gear with me all the time if I go out at night or swimming in the ocean (I'll have to lock it up back at a hotel or hostel), I've never thought about it before...  It is easier when I go to a national park and am the only human for miles.

Lenses / Help me justify the 17mm TS-E
« on: January 28, 2012, 04:39:16 PM »
I have been reading the reviews, and know that this lens can do things my 16-35mm can't.  But, what type of pictures besides buildings and cities can I expect to take with this?  I will admit that I like the results from this lens that other people have produced. (check out his other pics too).  I would like to know about taking long exposure night time shots with a full Moon, but no other lighting.  I know that at f/4 and an ISO of 400, it will take a while.

I also like the ability to stitch together panoramic photos.  I do need to look into an easy way to do that and HDR photos on my mac and be able to do them quickly.

Here is a picture that I found that shows what I don't like about the 16-35mm, but I'm not sure the way it was tilted here is perfect:
I really like the vertical lines in images and I have been having problems achieving that sometimes with the 16-35mm.
And I know that this lens gets great reviews.  But, do you think that it is worth the price and weight when hiking?  Maybe this lens, a 1.4x and a 50 f/1.2 wouldn't be a bad combination.

Software & Accessories / Tripod case for airplane carry-on
« on: January 02, 2012, 02:17:29 AM »
I have a Gitzo GT3541LS tripod, and I am having a tough time figuring out how to travel with it.

I have a Pelican case for both my computer and camera that I can carry on to the plane (two small Pelican cases merged into one bigger one due to the carry on restriction), but now I am looking for another Pelican case that could fit a tripod, clothes, and bathroom bag...and possibly a small tent.  My backpack does this, but only because I was able to strap the tripod in the thin bag to the outside of the backpack.

The Pelican 1514 case was just about 2 inches too short to hold the tripod without the head on it.
Sacrificing one section might be 'extreme' (and would save a little weight), but it might fit.  I would then use the existing camera case (pelican 1450) to carry the 300 f/4, clothes and nylon part of the tent.  That might work...

The other possibility is to get this case:
and carry the tripod and small ball head, tent poles, clothes, and nylon tent in there.

The third option is the non-airplane best solution.  If I got the Pelican 1700, it would be the right size for truck and car trips, and allow me to keep the Whimberly head on the tripod.

Or maybe there is some other backpack that it might fit in that I could use to go hiking/camping?

I have been know to wear multiple layers of clothes through security to save weight.  The TSA loves me...

Lighting / Color temp of pictures using flash
« on: December 26, 2011, 12:16:48 AM »
I am trying to practice using my flash some more.  I use manual settings, and the exposure meter seems to be pretty worthless when using a flash.

I might be able to post some pictures if it helps, but what is happening is that if I have a quick shutter speed, the pictures show up white.  If I slow the shutter speed down and still use the flash, it matches the actual room color (a yellowish soft white light).

I think I changed the white balance from Auto to Flash, but that didn't seem to make a difference if I remember right.

And I don't understand most of the settings anymore on the back of my flash.

Or do people use a yellow filter covering the flash?  Do you have any other tips?

Lenses / 85mm f/1.8 or 300mm f/4 for baby photos
« on: December 20, 2011, 11:19:53 AM »
I'm not the best photographer of people, and have never taken pictures of babies before.  But my sister is going to have twins in the next 2 weeks, and I would like to take some good photos with the 5Dm2.  Preferably without my 580 flash...

I won't have very much time to take the pictures, and there will probably be in-laws, cousins, and parents around.  And I know that they will take the 'typical' photos.  I am looking for more of the photo book quality pictures.

I do have a 25mm extension tube that I have used on the 85mm before, but it wasn't easy to get it in focus, and the camera had to be very close.  Or I have the 1.4x that can make the 300mm into a 420mm f/5.6.  I think I have used the extension tube with that setup before to get some macro shots as well.

If you have any tips or advice, I would appreciate it.

Lenses / Astrophotography telescope 'lens'?
« on: December 02, 2011, 06:53:09 PM »
Over the last two nights I have been using my 5Dm2 with a 300 f/4 with a 2x & 1.4x stacked teleconverters to get it to 840mm, and it took some great pictures of the Moon, although I think another 2x would be good for the Moon (~2000mm to get it full frame).  At 840mm, I could see Jupiter and 4 moons, but Mars is too small.  I would guess you would need ~25000mm to get Jupiter full frame on a 5Dm2.  I might need to get a planetarium to get that size of a telescope...

Besides the auto pointing tripod, do you have any other suggestions?  Would I need to support the camera hanging off the side?  Could I use the teleconverters to 'zoom in'?  Has anyone had any luck with this type of setup?  Is there a better telescope for this kind of photography in the $2000 range?

Lenses / What gear and lenses should I get next?
« on: November 29, 2011, 07:25:27 PM »
I currently have a 5Dm2, and a 16-35mm, 85 f/1.8, and a 300mm f/4 lens.  I am trying to write this post to keep my thoughts straight, but any suggestions would be good.  Or maybe Santa is real and this is my Christmas list.

I am probably going to get a WFT grip, and the GPS adapter to geotag my photos when I take them.  I would still like a better option from Canon to automatically geotag photos, but this might be it.  Expensive, but better than doing it in post processing for thousands of pictures.

Next, I am going to get a bigger Pelican case.  I travel by airplane, and need to be able to fit my camera, tripod, laptop, and clothes into a case to get past the two bag carry on rule...

The lenses are the next thing, and this is where it gets complicated.  The 50mm f/1.2 is at the top of the list for it's ability to shoot in lower light situations than my 16-35 f/2.8 or the 85mm f/1.8.   But, I am also considering the 14mm, the 8-15mm, and the 17mm TS-E.  After shooting at 16mm for a while on a FF camera (and I have borrowed an 8mm f/2.8 Olympus lens that is interesting for the Milky Way galaxy), it is the distortions in the corners of the 16mm focal length that I would like to correct.  I am thinking that the 14mm or 8-15mm won't be 'different' enough from the 16mm-35mm (at 16mm).  I would have to rent them for sure.  The 17mm f/4 TS-E is probably the best choice for me and the landscape pictures I take, I just worry about the f/4 not being fast enough in low-light conditions.  It will take a lot of practice to use it right...

Down the road, I would like to get into astro and Sun/Moon photography...I am looking to get a good tracking telescope that I can mount my camera to, with easy GPS setup of the tripod...  And high enough zoom to allow me to stack images and get something good, but figuring out how to do that, without spending over $2,000 isn't easy.  (I'm not saying it can't be done, I just haven't researched it enough.)  I wish it was like, there is one 50,000mm 12" telescope with a Meade tripod with easy star finding and tracking ability...maybe there is.

Software & Accessories / Is a new WFT-E4 IIa being developed?
« on: February 24, 2011, 06:52:31 PM »
Or does anyone know what is going on with this?  Most places on-line are 'out of stock', Adorama looks like they might have some, but is a new version coming out?  Maybe with GPS built-in???
