Third Party Lenses (Sigma, Tamron, etc.) / Re: Samyang 14mm f2.8
« on: June 21, 2013, 02:27:41 PM »
Looks like the IQ might exceed that of the Tokina 16-28, which is the only other wide angle lens I'm considering for purchase.  It supposedly has some weird halo, making it unsuitable for night shots.  Any of you compared these two?


I have not, but I also have not seen a zoom lens that can compete with the samyang 14mm (Outperforms the 16-35 ii in IQ...)

As for not being able to shoot at night, I have never had a problem with it. I am not sure if you are talking about the samyang or the tokina having the halo you mentioned.

Anyhow some pictures taken at night for reference:

As an audio engineer relying on pci-express expansion cards and working on pro tools this new mac pro without any expansion card slots is a pile of crap. :(

I can see lots of studios moving to windows because of this.

form cripples function.

I know this exists but we are also using raid storage for example and I can't see why i should get a ton of extra cases / expansion chassis instead of checking out the PC world.


You don't have any NAS disk systems running RAID outside of your computers' cases???

That's pretty common these days, rarely do you depend on the disk drives internal to the computer case....at least in my experience with anyone doing serious data storage, redundancy and even backup (mirrored RAID disk systems, tape, etc).


NAS Systems are more for the home user, not for professional use. If this is a professional workstation as it is marketed to be, no one in their right mind would use an external raid array. Too much too loose. Much better off getting a workstation that has advanced raid controllers in order to adequately support a large internal hd array. Anyways, my bet would be the mainboard in this computer wont support past raid 5.


Funny, in my server environments...we have SAN storage...effectively NAS....

Very seldom n the high end systems I work on for my day job, do I rely on servers with internal storage....and I'm talking multi-multi-terrabytes of data. Per server.

I'm quite used to using off server storage, with different RAID levels....different filesystems, etc. I'd say it certainly is professional in level to have your storage external to your CPUs.



Kinda funny when you omit my comment about how this is not applicable to servers and your entire response is about servers...

There is no use arguing apples and oranges.

But then again, anyone serious about doing "serious data storage" uses server racks. Totally different ballpark and not applicable to this thread.

All this computer is is a overpriced cylinder with decent components and NO ability to expand in the future. But hey if you want to throw away $3-4k be my guest. I could build a computer with a Xeon E5-2687W for considerably less than this costs.

HDR - High Dynamic Range / Re: Post your HDR images:
« on: May 09, 2013, 05:23:26 PM »
well It was not  about the motive, its a bridge against the sun, nothing fancy  . It more  about  that I can dig out information from one raw file from sun into shadows with out banding and noise in the shadows. You need two different exposure to do the same with a Canon, I can do it hand held, you must use a tripod. This file are now saved 4 times as a JPG =not optimal.

Ahh and all hope that this thread wouldn't be hijacked by the dynamic range discussion is gone. Please try not to ruin this thread like you have ruined many others...

If you have hdr pictures to post, this is the place to post them. Take the dr discussion elsewhere.

Software & Accessories / Re: Adobe to Stop Making Packaged Software
« on: May 07, 2013, 04:55:16 PM »
A swap to this model of using Adope CS6 will cause some problems for big organisations that have to secure their datas .
The head of the IT department in the organisation where I work, is in doubt whether the state bureaus is allowing to open the firewall/safety-solutions to use this cloud based software. It is to risky. They are in fear to get hacked.
And we own really a lot of CS6 licences.

Okay, repeat after me: This is NOT a cloud application. This is Not a cloud application.

From Adobe's website: "And, as always, your applications live on your desktop, not in a browser and not in the cloud."

It is just a confusingly-named marketing scheme.

The problem I have, regardless of whether the software resides in the cloud, on your desktop or on Pandora, is a requirement for an internet connection so that every time you start the application a license check is performed.  That would cause a great deal of heartburn on my part.

It is not going to be that restrictive. The licensing server will either need to be connected to once ever 30 days or every 99 days. I have heard both numbers from adobe representative, so I am not sure which is true. My guess would be 30 days though.

Can't wait to see the stock prices plummet in the morning. Any profit gains in utilizing a cloud based program will be lost due to the loss in share price of the stock.

Also if it can be used on a computer offline for 99 days, I assure you that this will be hacked and a bypass to the licensing server will be out within a couple days of the initial release. Don't underestimate the individuals out there who crack software. The top few hackers that develop these workarounds are light years smarter than anyone working at adobe.

As an individual who purchased cs4 and cs5e, I will too not be a part of cloud based software marketing. I will be awaiting the pirated version, for all loyalty to such a company who shows such disregard to the interest of their customers has been lost.

Lenses / Re: Best lens for capturing the Milky Way?
« on: April 28, 2013, 09:41:50 PM »
i think you want the samyang 14mm. I have one that i use for the sort of silly stuff you can do with 14mm, and astro shots. I've yet to aim it at the stars because i've been so busy, but i'm pretty pleased with it for the more earthly shots i've taken with it.

I took some shots of a wedding couple last night with it. i had to convince them to step closer, closer, closer still. "i swear, i'm not just taking a photo of your belt buckle!"

I think you're right, I just have two questions, does the lens have a hard stop at infinity and is it sharp enough wide open?

Yepp it does and it sure is performs wonderfully wide open.

If you dont use the cd/dvd drive too often, I have heard that you can remove it and put a ssd in its place. Because that will be a sata connection, it will be the fastest.

I have a server with windows server 2012 on it, but I wouldn't be caught dead using one of it's disks as a scratch disk. Way too slow. NAS would be even slower.

5D MK III Sample Images / Re: Set From Death Valley National Park
« on: April 14, 2013, 11:15:32 PM »
Nice shots, but I have to agree with everyone else... the watermark is atrocious. Anyone with some decent skill in photoshop will be able to remove that in minutes. If you photo gets stolen, who cares? If someone wants to steal it, they are going to steal it.

Plus, dont forget that there is a huge hacking community around the world that would rather hack your computer than bother photo shopping that watermark out. Then they have access to all your files. And same goes for hacking - if someone wants to hack you, they are going to hack you 

Best not upload your photos at all if you are that paranoid. But then whats the point of photography if no one sees your work?

First was the superior glass canon offers. It was significantly cheaper and better than Nikon when I got into photography. Now canon's recent price strategy is making me stray away from the $1500+ lenses. I am just hoping completion from sigma, tameron and samyang drive down the prices of canon's lenses.

Second was Magic Lantern. It transforms the camera into a whole new machine. All the features and capabilities are what keeps me committed to the canon system

And third is the video capabilities. No need to explain why, since everyone knows the profound effect the 5d ii had on video.

Rather than quote everyone who responded to this forum, I would like to thank everyone who responded! This was the information I was having a hard time finding on the internet and learned a lot from all of the responses.

Thanks again  :)

Hi,

I think for  planets a webcam is more often used than a DSLR (those are more suitable for DSO).
I don't know if there is an astronomy club close to you?, you could go out there to get some information and possibly ''play'' with some of the gear available before purchasing any.

I have a dobson telescope and used it with an adapter to take pictures of the moon and saturn/jupiter.
Results of the moon are great, but a full frame body for planets is not putting enough pixels on them.

Also for planets / nebulas (basically anything but the moon), you combine many images to get a far better result.

For DSO's you want longer exposures and need a good tracking system, then afterwards you correct each image before combining them to 1 image ( ideally you use different filters: for example for a galaxy a R V an B filter, take multiple exposures (different lengths) in each filter to reach a certain number of counts that reach your sensor, then you correct each image for a : flat field/dark/bias and combine the different images to one nice image).

This requires a good tracking system, ccd and software.

There are lots of people who make beatiful images with their DSLR (they also correct for dark i think), and us tracking system with follow scope(to ensure the tracking keeps tracking correctly).

Last time i checked tracking systems (even simple ones) were quite expensive (eq5 and eq6 were 600-1200 dollars), a good dobson telescope for DSO is another 1000.

For planets a ''simple'' refractor and 20$ webcam (modified) will yield better results than a dslr!, you take hundreds of images and combine them afterwards with software.

I think you dont need a good tracking system for that either , a bit more work on aligning the images afterwards maybe but it should be doable.


The moon is the most easy to do, but you will want more, where i live there is an astronomy club(not 2 many members), where for 50 euros/year you get membership and access to the telescope ( +- 24 inch/60cm reflector with a great tracking system, where you can connect your dslr with an adapter).
Alternatively you could visit a university for more information!, most people who are into these kind of things love to share knowledge and give advice/tips etc.

If you got something like that close to you, there would be no need to spend a lot of money , and you can photograph different objects ( moon/planets and dso's). Or at least orientate a lot better before spending the money!

Hope it was of any use.

Thanks for the very informative reply! I was hoping that I would be able to get started for around $600 or less, but it looks like I was dreaming! Better start saving I guess. I will definitely look into astronomy groups or using the telescopes at the local university until I have enough saved up.

I was hoping I could get some advice regarding using a camera for astrophotography. Any advice is greatly appreciated!! I am not looking for exceptional pictures of nebulas, but something that can take pictures of some of the larger planets and the moon.

Unfortunately, my budget is rather limited. As much as I would love a star tracking telescope system, I am hoping to settle for a dobsonian reflector.

What I am looking at is as follows:
Orion SkyQuest XT8 - F/5.9 @ 1200mm (build a scope version)
Orion 2" low profile focuser
Canon T-mount adapter and Orion 2" Zero-Profile Prime Focus Camera Adapter
And a kit of 2" eyepieces for when I want to do viewing rather than imaging

I read that refractors are considerably better for astrophotography, but ouch are they expensive. I am always open to suggestions though!

I am hoping to get into astrophography, but fear spending money on a system that isnt compatible or wont give good results at all (I have heard focusing issues is a common problem).

Thanks! Feel free to post pictures you have taken or of the setup you use to photograph the night sky!
Back in the 70's and 80's I did a fair amount of astrophotography, using film. And I was involved in the making of telescopes, mainly reflector types. While times have changed, the basic techniques are still the same.

As a rule of thumb, a refractor is a good telescope for planetary use. High magnification, and good contrast. Reflectors are better suited for deep space use (the secondary mirror tends to reduce contrast a little). That said, they both can be used for general astronomy.

For tracking, an equatorial mount is best, although, I believe an alt-azimuth mount can be used with todays computer controlled systems. Dobsonians are really best used for visual observations, as they tend to be set on a simple alt-azimuth mount, which is manually controlled. I tended to use an equatorial mount in the field, and use a small guide scope to keep things on track.

From a camera perspective, the Canon 60Da is designed for astrophotography. It has the IR filter removed and a number of other enhancements. In the film era, it was common to run exposures (for deep space objects) for up to 2-3hrs. In the digital era, its more likely to take a great number of short exposures, then combine them later. This is done to cope with sensor noise, as long exposures tend to get very noisy.

I got carried away with the wide apertures and long focal length of the dobsonians, so I didnt give too much thought to a refractor. Maybe picking up an astrotrak and using my 70-200mm may be a cheap alternative given the cost of the equatorial mounts?

I am hoping to grab a 60Da the next time lens rentals does a promotional sale and lists that camera. Hopefully that will be soon because I just found a wonder spot away from all of the city lights!
