You website is really nice!! I am a beginner using DP1 but I can understand more how to control it after go through your blog. I come from Hong Kong and wish to know more about how to minimize the green corner problem. Is it the 1.01 firmware already fix the problem? I found that even the updated firmware still have this problem. Do I need to tune it in new SPP? How to do it?

Thanks for your help. ^__^

IMO, the best thing about DP1 is that it is so small. You can mount it on little mini tripod and easily take long exp. pictures in pubs etc. without paing attention to yourself. Try to do that with full size DSLR with normal tripod :D

Unfortunately the firmware update didn’t bring a larger movie mode. I think you probably know but can’t tell if we’ll see a Sigma camera with a useful photo/movie combination later this year. If correct just blink with your eyes ;-)

I also would like to know if the video out of the DP1 is live during photo shooting and movie recording e.g. can you monitor the camera on a connected TV while taking pictures and also during movie recording?

Thanks for doing an excellent job of getting information
out and I like your photography,

Perhaps you can help me with a small problem:
I am running the Sigma DP1 software on a 17 inch MacBook Pro
I don’t seem to be able to eject the software CD no matter what I try, a message always comes up “the CD is in use and cannot be ejected, close the programs” , I have done that several time and even rebooted several times, I have tried to purge the program, however a similar message comes up ”
this program is in use and cannot be put in the trash”, eventhough the program is not in use.

Any ideas ?

Thanks Peter

In the studio I did use MF on close ups, but not when taking a step back - half / full body shots. Bowling half half. Not very easy to use MF when everything is moving and loud music is playing. haha. But same there. if there is something close - it’s easy. If not then I trust AF.

I´m just woundering because i have set studio light hundreds of times..

Only with profoto-flashes… And if i get a reading of lets say F/11, 100 Asa
on the lightreader then it dosent matter what kind of format i use ( everything from 135-fim up to 8X10 and mark III and Halsselblad H2)

(drnoise, hope you mean dof about the F-stops or else you have no clue)

The hasselblad syncs on all times so we usualy shoot it at 1/500 sec…

This would not have workt for you using Profoto flashes,right?if i lets say were shooting 1/500, F/16, 100 asa..

But heres a tip for you if you ever end up in that situation..Use your ND filders…8-)

Peter, there is no temperature slider in SPP and I guess we will have to wait for that to be implemented. But I use another software called Raw Developer and I have high hopes for it’s DP1 support in the near future (with temp sliders as well as a different apprach to colors in general).

Today there is no way to “copy” a WB setting from one shot to another inside the camera. I’m not sure this is possible inside SPP either. hmm.. I will have to get back to you on this one.

The only way for me to be able to actually take a shot would be to get a better shutter speed and thanks to the electronic central type shutter I can go beyond the limit of 1/200s x-sync that the SD14 has and reach somewhere around 1/1250s if flash and radio sync allows it. Now, I felt that 1/640s worked great at F9 and didn’t have to go higher. I guess I could but there was different type of flashes involved and some slower then others and the safe bet was to stay around that speed. (one ring flash was connected to a battery and therefore a bit slower)

Cryptic? If I had my camera with me as I write this I would have given you the actual exposure settings that I could have used in order to work with a F22 - 1/250s medium format shooter.

From Wikipedia about X-sync. “X (xenon) sync is a mode designed for use with electronic flash. In this mode, the timing of the contacts coincides exactly with the full opening of the shutter, since xenon flashes respond almost instantly.

Due to their construction, focal plane shutters as used on most SLRs will only allow xenon flash units to be used at shutter speeds slow enough that the entire shutter is open at once, typically at shutter speeds of 1/60 or slower, but some modern cameras may have an X-sync speed as high as 1/500. Electronic shutters used in some digital cameras do not have this limitation and may allow a very high X-sync speed.”

Read more about shutter: http://en.wikipedia.org/wiki/Shutter_(photography)
and x-sync: http://en.wikipedia.org/wiki/X-sync

So probably there is no much difference between APS F11 and MF F22.

I have your word for SD14 reds in SPP2.5, now you are in charge ;)

Why did you get perfect result shooting at f/9 when the flash reads f/22?

Time is not a factor when shooting only flash, as you know..

Did you get the same exposure if you shot at let´s say 1/60 s?

Just knew that we will have the new firmware for DP1 and SPP update (both Mac and PC versions) on 11 Apr!

I think you will be busy to do testing again :)

So I sometimes forgot to take the ND off. But the last two shots is outdoors and a good moment for ND’s. :)

My DP1 has arrived at the dealer tomorrow so I should get it this week.

Can’t wait.

Great to see Sigma making strides in its software too.
