Aerial Photography and Video > URBI interface rules out RAW format on Canon G9??

Hi there,
I just tested connecting my new Canon G9 on my camera rig.
The basic functionality is fine, shutter and zoom works.
I programmed the URBI to operate in Tv (shutter speed select) -mode and to shoot 2 pics for every trigger, and so it does.
Before connecting the camera to the interface, I set the camera, in Tv mode, at 1/500S and RAW format mode. And when triggering on the camera button it works as supposed, shooting 1/500S and storing RAW pics.
BUT: As soon as I connect the urbi interface, the camera shoots Tv 1/500S but RESETS the format to JPG Superfine Large, refusing to shoot in RAW. And RAW is what I whant to use!

Anybody else noticed this phenomena? Remedies?

Hey Snurre

as far as i know the RAW mode are unavailable with these interfaces, ive got the Blip URBI, that one rules out the raw mode, and im now looking into the CAMremote-1 unit http://rc-systems.net/camremote.html

They also states that the raw mode are unavailable with this interface, so i guess this is a common issue with this accessories

Anyway, i dont shoot in raw anymore in my daily work, cause i find it useless in most situations, after all, most of the pics will be saved in jpg anyway, so it will look the same in the end...

If you shoot in Tv mode during broad daylight, there are small chances you will need the "extra adjustment" possibilities raw format have.
At least thats my experience...

I only shoot raw in bigger assignments, but just more as a psychological backup and if large formats are required

Never argue with an idiot, he'll drag you down to his level and beat you with experience...

I've got to use the CHDK load to be able to shoot RAW with my A640/CamRemote. I hear they are nearing completion on the G9 version of CHDK so perhaps you'll be able to use that soon. Though, I don't know of the URBI supports CHDK. CamRemote does.

Yep, can't wait. Hopefully it will allow full display so you can see what the heck the shutter/aperture settings are.

The URBI, Canon A620, and CHDK give you both jpg+raw if you want it. A G9 version of CHDK may do it.

Thanks guys for very enlighting responses

And Hi to you all and especially my friend Daytona , some time no see.

Ok, so I did not know that the URBI had these bad desire to decide for me what format to shoot in, but now I know.

I had never heard about the CHDK but now I made some research and it might just be the solution for this problem, thanks for the hint!

The reason why I want to shoot RAW is because I believe that I might get better final quality doing so, but I have not yet verified that this is so. However I read some G9 review on one of the major review web site and the reviewer complained about the quality except for the pics shot in RAW mode. My own shots on ISO200 JPEG max quality confirmed my concerns, it looked kind of grainy and smeary in the same time - mind you, then I compare to the Nikon D300 RAW files I am used to normally, and I am aware this comparision is not fair.
Maybe the Lightroom RAW to JPEG converter makes a better conversion than the integrated algoritm in the G9? I will have to find out. But now I know it was not just me handling the camera setup wrong, the problem is verified. And you gave me a way to look for the solution.

You are good guys

Howdy!

Regarding RAW,
If the photograph is captured in good lighting and the contrast is not excessive then it is possible to capture good JPEG images. RAW is particularly advantageous for difficult lighting and in particular high contrast. You can only obtain any significant benefit from RAW if you use the RAW editor to improve the tonal range and there is much more flexibility to do so with RAW.

If you want to work on a picture and/or resave it several times, save it in TIFF as this format is lossless, jpg format tend to get degraded after 2-3 resavings.

Yes, you will ALWAYS see a huge difference between a compact and a DSLR, when making side by side comparisons, due to the fact that the sensors are quite different in sizes, smaller sensors are more sensitive to light cause the same amount of pixels are squeezed in to a smaller space... this is noticeable on most compacts from 200 iso and above, so, size DOES matter

But, if we are looking at RAW for AP work, which in the end 99% of the cases will be saved in jpg for customers ease and use for web etc, you will hardly see any difference between a jpg of the camera, and a post processed RAW out of the camera when the final file will be jpg after all, and thats if were shooting in broad daylight, as most of us will do.

Bottom line; RAW is more post work, gaining microscopic improvements over jpg. (if saved in jpg after all)
Do a test for your self outdoor a sunny day (with the same camera) one pic in jpg, and same one in RAW, edit the two pics in the same way, and save them both in jpg, you will find it hard to tell the difference, even side by side, and all that work for so little

Canon G9 the camera to get?

This is a really good post, lots of good info in here. I am looking at getting a Canon G9 for AP work, is this still the camera to get, or should I get something else? I already have CAMremote that I am using for my AV work. I really value your guys' opinions when it comes to me having to make these decisions, you guys have tried this stuff and know what is good and what isn't. Which is very helpful for a rookie like me .

Thanks

Denny, you will find many different opinions on that question/answer.

But all in all i think the G9 produce well enough if youre not comparing it to a heavy Dslr camera... remember, the details you usually notice or need to be razor sharp are in these cases so far from the camera that it doesnt matter much, thats my opinion as a fulltime photographer, but others might disagree

We have used the G9 for a while now and have found the images to be noisy over ISO100. This tends to limit your shots a little in anything but really bright conditions. The trouble is that the aerial application is just so critical that normal test shots such as you see on DP review don't really give a good indication of how the cam will perform on the heli.

We now tend to use our trusty 350d - no noise right up to ISO400. Yeah, btw, we found out too late that the URBI won't do RAW on the G9!

Hope that helps.

Thanks, Cameraman

Seems we have the similar experiences from the G9+URBI.

Probably I will mostly stick to the D300 with VR zoom lens. But it IS heavy...

Daytona, I agree to some degree, still.... the D300...

I have found a sigificant improvement in image quality converting from Raw to Jpg in CS2 for shots taken with my 5D. The shots side by side are nowhere near the same. I was surprised by this.

keepin' it real

Stet!

Really, care to share some examples with us here, cause thats not my experience...
But when you say nowhere near the same, what do you mean by that, colors, sharpnes, grain, or what?

Snurre, im considering a canon 450D, since it doesnt way more than 480gr and that its faster an less grainy above 100 iso.
Shutterspeed is a prioroty after all in this business.

I think i got hung up in the nice video mode the G9 have, but its time to be more realistic i think
