O.K folks I have had a 30D for two weeks now and i am loving it. But 1 thing is has been annoying the crap out of me and i was hoping that someone may have the answer for me. On the mode dial (left hand side top of camera) there is the green line that you use to line the mode that you are choosing to. Next to that is another mark (green circle with green line through it) What is this for??????
Also with auto exposure bracketing I can not seem to shoot off the 3 frames for bracketing automatically, I have to manually release the shutter button 3 times. Is there a setting that i am missing here? as i am sure that when i first used the auto bracketing that it did shoot the 3 frames automatically.
Lastly Is any one else having problems with the camera download software? as i now have to use a card reader instead of the usb cable to upload files from the CF card.
I have spoken to canon regarding this and walked me through a fix... but it did not work.
Any ideas 30D owners? |

well i have the 20D and i think i can answer one of you questions
i think that he green line with the circle represents your focal plane (basically where the sensor on the camera sits)
i could be wrong but it is on my OLD Canon FTb film SLR and im pretty sure that is what it means
i would just make sure that the camera is in the burst mode when doing the bracketing. the only other thing that i can think of is in the custom function i have a setting called "Bracket sequence/Auto cancel" and mine is set to "0:0, -, +/Enable
good luck with that and the software. i actually installed the disc that came with my friends 30D on my computer cause i lost my install disc and hte software works fine for me. is the computer not reconizing the camera or is there an error that pops up in the software?
edit* added + spelling

Odd. On my 30D, the circle with a line through it is not green, it is white... ish.
I will confirm that this is indeed the sensor plane indicator mark. This can also be found in your manual.
All SLR's and DSLR's have this. It's important because a small number of shooting situations require that you measure for the optical center of the lens. This is found by measuring forward from the sensor plane by the number of MM of the lens's focal length (quite simple with a prime lens, can get tricky with a zoom lens).
I'm not sure about the software. I only ever use card readers. I can't be bothered to waste my camera battery with USB. I have a very cheap PCMCIA CF card reader which slides into a slot on my Tablet PC. It's not insanity fast, but it's plenty fast enough.

I confirm that the circle-with-a-line is marking the sensor plane, And it's a very useful mark indeed, not just for the reason eschelar stated but because you can use it to measure precise focusing distances in macrophotography.
I can't imagine why anyone would want to use the camera to download their images. The card reader is a much better solution.

My cirle/shite line is white too..perhaps your camera is moldy? LOL
Why bracket? I know why in the film world, but in teh digital world...first, shoot RAW - you can push it 2 stops up or down and change the WB as well (among other benefits). So i just don't see the point to shooting bracked exposures or WB. Not even sure why you'd ever want to bracket WB anyway.
I only ever use a card reader. the only thing i've ever hooked my camera to the computer for is to put my name in the camera. Shooting tethered is a temptation, but I have having even a flash sync cord attached to me.
I am a bit perplexed (ok, pissed off) that the wi-fi for the canon SLRs is $1000, but you can buy p&s cameras with a wi-fi for only $50 more than the non-wi fi version.

Put your name in the camera?

I think he means adding it to the EXIF database in the camera, show it shows up on all his image EXIF files.

You'd bracket WB if you were shooting jpg in uncertain lighting conditions, primarily. No point to it in RAW, nope.
But exposure bracketing is another thing altogether. Moving the slider in RAW is not the same thing as changing the exposure. It allows considerable compensation, sure, but it's still best to nail it as close as possible at the time of exposure. The closer you get it, the more flexibility you have in RAW for meaningful adjustments. If you're within half a stop one way o the other it doesn't matter, usually, but in extreme lighting conditions (like directly into sunsets) bracketing is a must. Plus, with bracketed, tripodded exposures of stationary subjects you can combine images for increased dynamic range.

I believe so, yes. I've never done it, but I believe I have seen it mentioned.

Canon Direct Connect, I believe, is what you use to do this. It's very simple. Also a great help if the camera is ever stolen, I would think, at least you could easily demonstrate ownership. |

Hi Rob
just checked this old thread i started and saw that you left a response to(sic)
"You'd bracket WB if you were shooting jpg in uncertain lighting conditions, primarily. No point to it in RAW, nope.
But exposure bracketing is another thing altogether. Moving the slider in RAW is not the same thing as changing the exposure.

Plus, with bracketed, tripodded exposures of stationary subjects you can combine images for increased dynamic range."
I agree that using the RAW exposure correction is not anything like in camera exposure compensation. However, trying to compare camera film settings to digi, I was sitting down last night playing with the 30D shooting some low light in the lounge room (at 3200 iso) and comparing the results via preview on the camera LCD "visually". What I found was that using the camera TTL exposure settings(30D, full manual, 1/4 @ f4.5, using spot meter) the shot was way over exposed by what I was actually seeing (by at least 4 stops). Have you found this happening with your 20D? I can't believe that the canon TTL metering would be 3-4 stops out in this situation! Is this something that in digi photography needs to be manually compensated for as a rule of thumb? or is the Canon TTL metering that far "out" in low light situations?
Your thoughts?
Has enyone else found this to be tha same?

And fot the record, the circle thingy on my camera is white! OK!!!
I feel like a goose now but can someone explain in "dummies terms" the "sensor plane" thing that Bear was talking about and hoe to operate it on the 30D, also is there anyone in Australia with the 30D that can tell me where the hell it the circle thingy is refered to in the manual? :-( |

It is not something that you can operate. It is a line showing you where, if you were to cut the top off your camera, you would see the image sensor inside your camera. For some types of photography it is useful to know where this is (without cutting your camera in half).
My example further to the two already given is in relation to taking a series of photographs in a row and stitching them together digitally on the computer: you need to know where the sensor is in order to calculate the point around which you should rotate the camera to obtain a perfect image (technically: in order to avoid parallax errors).
