Landscape / Re: Milky Way

Well captured!  What was the camera you used?  I'm guessing a FF (perhaps 6D or 5DmkII or 5DmkIII?)


5D3

If it's $10 for life, I might jump on it even I already have LR4 and CS6.

But if it's $10 for e.g. 12 months, and then some ridiculous amount, no way.

So can someone confirm how long they promise the $10?

Went out last night to shoot Milky Way. I had my friend's 24/1.4 with me. It was late and I was tired so I forgot to try also with my Sigma 14/2.8. But the pics with 24/1.4 came out quite nice. Even I drove to North-WA trying to get away from light pollution, still there's quite strong light on the bottom.

Comments?
Comments: Nice picture... the light pollution at the bottom seems to add to the image and gives detail on the landscape, yet fades off quickly enough to not overcome the details of the stars.. it works quite well together and makes it a more interesting image than just the stars alone.
Questions: What was the exposure and ISO?

Thanks for the comments.

Here's the settings: 15 sec, f/2, ISO 6400

I first shot at 30 sec, but peeking at the photos I noticed some star trails even the 24mm should be fine up to 30sec. So I decided to use faster shutter and higher ISO.

Lenses / Re: 16-35 I vs. 17-40

I  don't have a horse in the race,  but I'm surprised at how disrespected the original 16-35  is.   I'm also surprised at how respected the 17-40 is.  I learn something new everyday.

I think it's part about expectations, especially when the other one is twice the money, you'd expect plenty more from that. Also you'd expect plenty more from F2.8 compared to F4.0. If it don't deliver, then it's not the winner.

I have a couple 64GB Sandisk Ultra 30mbps cards and a 16gb Sandisk Extreme 45mbps card, both cards cannot handle 1080p All-I or IPB. I have to knock it down to 720p if I want to record long videos on the SD cards. I can record up to 5 minutes tops before it automatically stops recording on those SD cards.


I have had quite the opposite experience. I have quite a few Sandisk Ultra and Extreme 8gb cards and they work flawlessly shooting 1080p at 24p, 30p, 50p, and 60p with IPB. As a matter of fact, I did three quick time lapse videos the other day and had my mkiii record at 1080p 24p with IPB for 27 minutes each onto different Sandisk Extreme 8gb 30mb/s cards, and not once did it give me a problem.

Interesting. I don't know what's the bitrate on 5D3 codec, but my Panasonic camcorder which records 1080p60, requires Class 4 SD cards (or better), which means 4MB/s is good enough.

Sounds awesome. I wish I could do similar trips. When you're going? How detailed trip plan you already have, or do you just go around without much plan?

I fly on Nov 4 and I NEVER have a plan or reservations (other than airline). Serendipity rules. One issue I'm running into again is that Vietnam, Burma and China still won't let me cross their borders on my bike, so if I want to visit them, I have to fly in like everyone else. Any interest in meeting up in Yangon for a photo-tour of Myanmar?

Nice. I did once 2 week trip to Thailand with only airline tickets booked. Then I usually did the bookings for hotels, airlines or boats 1-2 days ahead.

I'd love to go around SE asia for photo tours, but that'd require things like vacation, and especially permission from wife  ;D Most likely my next trip will be Japan.

I have to have a laptop too, which is why I carry the smallest one out there (11-in MacBook Air), because I write travel stories and design/post web pages from the road. This means doing basic sorting and image editing both for my website and for a newspaper I freelance for. I also upload my GPS tracks to LR4 on the laptop, so that I can encode each image with location data. I've been doing this for years and have developed an efficient workflow, so it doesn't draw much time away from the more important travel experience. In fact, spending so many months alone on the road, often not speaking the local language and confined to my tent at night (rain, bugs, middle of nowhere, etc.), I find looking through the day's catch enhances the experience and helps me learn what to do/not do the next day, with regards to photographic technique.

Oh, and there's not one cubic centimeter of space available for souvenirs--so my photos serve that purpose.

you would consider leaving the 1Dx at home?

Does not compute. I would have it welded to my arm.

Small portable solar panel to trickle charge your devices? Then you don't need to worry about power consumption.

I've looked into these, but the ones that put out adequate power are quite bulky and heavy. I can, depending on which bike I'm riding, charge a camera battery off of the engine while moving, but it's awkward and again, only possible on certain bikes.

On my bike, I installed a trickle charging device (to keep the battery charged when I store the bike for winter), and the special connector on the device works both ways, so when needed I can plug normal 12V devices on the connector. On my bike trips I bring e.g. 12V cell phone charger. If I really wanted, in theory I could bring my inverter, and thus get the standard 110V/230V AC for small power devices (~<300W).

For the solar panel, because you're space limited, you don't want the big ones, but small one combined with e.g. 10Ah power pack. The small solar panel will charge the power pack over time, and then when needed, you can power devices with that. If you want big enough panel to directly power devices, then they are big/bulky. I think e.g. Duracell has those power packs you can charge with small current USB, and it'll give large currents when needed.

Canon General / Re: Help design a time lapse rig
« on: August 31, 2013, 10:00:57 PM »
Mostly copying from other people ideas:

-more than 1 axis movement

-rotate / tilt

-individual parameters / programmable curves for each freedom of movement. E.g. rotate camera 1° every 1 minute towards left, same time move with curve x= 0.5t^2 - 0.3t + 5, y = 0.15t

-should support all common mathematical items, sin, cos, ln, log, e, ..etc...

-fast movement preview to verify movement. Hate to see the planned track to fail after hours of shooting (great idea Paul!)

In the US they are adding all funny warning labels, so maybe next one will be "The air you breathe might contain oxygen."

The advantages to RAW may be there, but they are blown completely out of proportion.

That one I do agree completely.

For me the big item is increased DR. The other advantages are minor, but I don't mind having them too.

And with computer speed and storing capacity increasing so fast, I find it easy to stay on RAW myself. For some people, I'm sure JPG is just fine.

OK, to make my objectives clearer, I could go on this 3-4 month trip with my current computer and HDD enclosures and shoot RAW, but I risk filling the HDDs too soon and slowing down my whole operation due to the size of the files. I'm often without electricity, so slow file transfers eat lots of battery.


That is tough one, I'm not sure how I'd solve that problem. Have you thought about those automatic CF-copy-devices, can't remember the name/models, but the simple device where you stick your CF / SD card and it automatically copies it to the internal hard drive. If you want mirroring, get two of them. That way you don't need to haul your laptop around so much.
