Hi guys,
I'm setting up a new computer workflow within my studio.
unfortunately i got no 39mpx camera at the moment to test it
Is an iMac c2dou 2,4ghz (4gb ram) powerful enough to store and show! 39mpx files during an unlimited tethered capture?
thx!

Yes, but if you plan to process the photos in Photoshop etc I would suggest upgrading to a Mac Pro with at least 8GB RAM.

And be sure to custom order a more muscular video card than the stock version.

Could you recommend some for the MacPro? Last I knew, there were only two to chose from. I happen to have the NVIDIA GeForce 7300 GT with 256 of VRAM. Oooooooo..... Anyhow, it seems to work fine for me.

Not specifically, but I do know the 7300 was a definite liability. If configuring through the Apple store, I would probably start at the $200 level (NVIDIA 8800) or higher.
I'm sure others ca relay real-world experience.
As raw conversions programs provide the complete raw file for previewing purposes, the video card upgrade will have a significant impact on speed.

thanks guys!
oh i thought that video power isn't important, someone told me that is only crucial to visualizing 3d

steve, when i scroll through images and its takes a bit of time to redraw, is the delay caused by the video card?
im trying to decide on what level of macbookpro to get.

I just got the new spec 2.5 with the 7200 hard drive, and 2gb ram (waiting on 4 to arrive). Both capture one and photoshop run fine on it (with 39Mpixel files), and are not particularly slower than the 3 Gb MacPro upstairs with 2GB (I mean to get more memory for this as well) and the 7300GT Even Photoshop with 3-4 225Mb 16bit tiff files runs fine on the notebook. You could completely upspec both your desktop and notebook, but I suspect the gains would not justify the price hike.
I didn't expect the MBP to be fast enough to be practical, but to be frank, it's perfectly fine. I think the limiting factor is as much to do with the speed to read the hard drive. For viewing purposes, I find that CS3 Bridge is very quick, particularly when you use the slide show to display images, which does a great read ahead, and still allows you to easily zoom to 800% if you really feel the need. I run the slide show on manual advance.
Hope this helps

I know that with the new Hasselblad software Phocus, that the Video card plays a significant role in the speed of the application. Traditionally, I have not emphasized advanced Video cards unless 3D was an application, gaming, etc.
But with the newer raw conversion programs like Lightroom, Aperture, Phocus, it's clear the Video card plays a stronger role than in the past. It's a change.

I would recommend going with a Mac Pro over an iMac. I know that price is probably a huge consideration, but the expandability of the Mac Pro outweighs the price savings of the iMac.
I think a good option is to purchase a basic Mac Pro and then expand as you can afford to.

If you move around a lot like I do from studio to studio, location etc., the 24" I mac is tremendous.
It's fast, self contained, set up is immediate and it seems to take abuse without issue. We shot with this thing from NY, LA, Tokyo, Barcelona, to Paris, used it at night to batch process many thousands of files and it just keeps running.
The screen is a litttle hot but for viewing on set it's bright and client friendly.
It will also run a 23" monitor.
In my test of shooting with the I-mac vs. the new toers using the P30+ and 3.78 I don't see much of a difference between preview rendering and no difference in capture speed when tethered.
For batch processing quickproofs and high rez the towers are faster, but for the speed offset your carrying a lot of equipment with a tower and one you have to be very careful with.

the iMac should be just for capture, display and storage files (shoot & forget). for additional digital workflow (basic retouching, processing ... ) i'm planing to use a macpro operated by an assistant during the productions
thanks again everyone for your suggestions and info!!!

I loaded Phocus beta on my Mac Pro quad core + 6 Gig Ram and the Geo 7300...Phocus ran painfully slow...Upgraded to a Radeon HD 2600 XT and things are much better..The only other option for a last gen Mac Pro is the ATI X1900, which has very bad reviews..over heating and poor reliability..
(BTW only the Mac versions of the above cards will work)

Thanks for the information about the video card & Phocus.
Does the issue with the standard video card also apply to other applications, like photoshop or Sinar Xposure?

Performance of CS3, LR and Flexcolor are minimaly (not?) improved with upgrade of video card..don't know about Xposure but I assume it is the same as the above. With Phocus, however, the impact was not subtle.

better go with Mac Pro.
i have both iMac and Mac Pro .
and now i leave the iMac for slideshow and gaming ...
once you get used to the Mac Pro. you wouldn't wanna to start your work in iMac.

it's as james mentioned
my intention for the imac is portability
-
An iMac or Macbook Pro will capture "fine"
except if you're capturing non-stop, the computer won't allow instant focus checking
as the RAWs are streaming in.

[a href=\"index.php?act=findpost&pid=185176\"][{POST_SNAPBACK}][/a]
why it won't allow instant focus checking?
-
Mine cannot with my CF39. It simply is too busy getting the RAW's in. I am using a MBP15/2.4Ghz/2Gb. Core duo so it is a bit older (no Core2duo).
-
You'd be able to check focus, BUT it would be frustratingly slower. Compared to a Mac Pro with higher bus speed (1.33 GHz vs. 800MHz) and more CPUs and more RAM.
An analogy would be:
Turn on your sink faucet full blast (non-stop captures streaming in). Now, stick you finger every now and then interrupting the flow. Get it?
It happens to be a world of difference, and why people haul heavy Mac Pros on location instead of using a laptop or iMac (which uses laptop motherboard and CPU).
-
This brings up another question:
Let's say you make 60 consecutive captures non-stop tethered....As the RAWs are still streaming in, someone yanks out the firewire cable. What happens to the captures not yet arrived into the computer? Do they come in once you reconnect the cable, or are they lost forever? This is where Leaf and Sinar MAY have an advantage with their large buffers. Can anyone clarify?
-
I am not so sure about that. Maybe Leaf & Sinar have the upper hand here over my Hasselblad but I am not so sure. The Sinar has this big solid state memory internally but is it also used as buffer? (Thierry?).
I have had the occasional cable coming out of the Hasselblad. Putting it back in the images that were on their way continued to come in.
I have never dared making a long serie, yank out the cable and putting it back in on purpose though. So I cannot be completely sure there will be no losses at all. The cable in the Hasselblad is placed in such a ridiculous place I tend to be quite careful. I wonder when the hooked connector will be there or when they will place the connector on the bottom of the back. No, you can ruin the backs connector when you trip over your cable but you definitely molest at least 2 cables per year (I used the same cable with my Leaf for over 4 years!).
