Photo Forum / Digital Photography / DSLR Cameras / August 2005On/off camera flash advice
I've got a Canon 300D and want to add a flash to my kit. I'm iinterested in two different applcations and one flash may not do everything. I've tried fo figure out the Canon, Metz, Vivatar and Sigma catalogs on the Internet and find I can't narrow down my choices. First, I'd like a flash that improves shots like this; http://www.panix.com/~adykes/CRW_9508.jpg This was shot at with the 28-135 zoom at near-max zoom with the on-camera flash from about 25 ft. I assume the smallest add-on on-camera flash would make a big improvement in the shot by allowing me to use a lower ISO and by putting some light on the faces. (the house lighting was worst-case, with just a single stage light.) Second, I'd like something I could use off-camera in sync with the on-camera flash. I found this flash that looks like what I want but it seems to be specific to Canon P&S cameras. I'd like to use it for side lighting for headshots, for example. http://makeashorterlink.com/?N2315178B How does the exposure calcualtion work with a two flash setup? Does a 300D camera do TTL flash measurement and exposure calculation? I'm not looking for the pro-level lighting and actually like the available light look for club photography. Thanks  Signaturea d y k e s @ p a n i x . c o m Don't blame me. I voted for Gore. > I've got a Canon 300D and want to add a flash to my kit.

Besides, with a GN of 18, and no tilt or swivel, it is only mariginally better than your on-camera flash. IMHO, the price ($110) is ridiculous - that must be $30 for the flash and $80 for the Canon brand. > How does the exposure calcualtion work with a two flash setup? That depends on the flash. If you use two or more E-TTL compatible flashes on a E-TTL capable body (your 300D is E-TTL capable), it is supposed to be taken care of automatically. Same if you use two or more auto flashes (auto works on any camera). Neither E-TTL are perfect, so you still might need to tweak the exposure, but in principle, they do the grunt work for you. For manual and vari-power flashes, you need to use a flash-meter or work out the exposure yourself from the guide numbers. > Does a 300D camera do TTL flash measurement and exposure > calculation? Yes, it does, if the flashes used are E-TTL-compatible /and/ communicating with the body. For a multiple flash setup, this usually means you need to have a master (e.g. 580EX) or a ST-E2 wireless controller in the hot-shoe. > I'm not looking for the pro-level lighting and actually like the > available light look for club photography. Selecting flash for Canon digital cameras come up so often that I've written an webpage on the subject. Please take a look at: http://folk.uio.no/gisle/photo/flash.html For club work, however, I would not use flash at all. Learn to use avilable light - it gives a much more authentic feel. Here is an example of a photograph I took of jazz pianist McCoy Tyner using available light only: http://flickr.com/photo_zoom.gne?id=29631309&size=o Signature- gisle hannemyr [ gisle{at}hannemyr.no - http://folk.uio.no/gisle/ ] ------------------------------------------------------------------------ Kodak DCS460, Canon Powershot G5, Olympus 2020Z ------------------------------------------------------------------------ >> I've got a Canon 300D and want to add a flash to my kit.

It'll take a while to digest the answers. That's a nice B&W stage shot. I assume it's desaturated from a color shot. Does that make the best of the image noise in a high ISO number on an available lite shot? Here's one of my shots. It's good but shot at desperatly show shutter speed. I'd like a stop or two faster shutter and a a little more light to fill in the shadows (just a little) get less noise. I need to take a zillion shots to get one where and the musician and I hold still for the same 30th of a sec.

No, this is from my film days (Kodak Tri-X B&W film pushed to ISO 1600 - those were the days... ) The grain you see is film grain. > Here's one of my shots.

If the stage lighting was too complex for correct w-b, you might consider converting to B&W.

The microphone is almost as much of an antique as the resonator guitar. Is that a metal bodied resonator guitar? > The white-balance is off, however. If the >stage lighting was too complex for correct w-b, you might consider >converting to B&W. I think that the direct light from the spotlight over his shoulder with the green or blue gel overwhelmed the auto white balance of your camera. I would suggesting manually selecting a white balance -- make a good guess if you can't take a gray card shot under the same lighting conditions for a custom white balance. Actually -- with the instrument and the microphone, B&W would look perfectly "period". :-) Only the microphones on the instrument are a bit wrong. Enjoy, DoN.

Here are the rest of the shots from the same show. It was an old-time & Jugfest night. I was switching between the on-camera flash and no flash on the 300d with the 28-135 zoom. The flash shots are *much* better and still have an available light look IMO. http://www.6gen.com/JUGS/ I love b&w photography but haven't played with digital b&w.

What I usually do for hand-held and/or moving subjects in low light is set the camera to ISO 1600, Tv-priority mode or manual, with the shutter speed set to one that will freeze camera blur and subject blur. In Tv-priority mode, I usually set the EC to +1, so that if there is enough light for the camera to do this, I get a nice "better than native ISO 800" ISO 800 exposure index. If the light is too low, I will get an under-exposed image, and it will be noisier, but not blurry. Manual mode is for when the lens' quality or DOF is not suitable wide open (which is what often happens in low-light, Tv-priority situations). When you under-expose, it is essential that if you are using ACR, that you set "Shadows" to zero, if you want your shadows; otherwise, they are clipped away.

I'm drawing a blank on what "ACR" stands for and have not heard of setting shadows to zero which I can sort of understand but have never seen instructions for, in camera. I can do it in photoshop but it can be a PITA. Signaturea d y k e s @ p a n i x . c o m Don't blame me.

I can do it in photoshop >but it can be a PITA. ACR is "Adobe Camera RAW". It has a setting called "shadows", which, when set to a number greater than zero, renders the darkest shadows in the RAW data as black. In a well-eposed image, this increases contrast without losing much detail, but in under-exposed images, that range is more likely to contain needed detail, and it is blackened away if the shadow setting is above zero. If you're shooting JPEGs, and not RAW, then they are most likely rendered in-camera much like ACR does with "shadows" set higher than zero.

Here's a simple answer based on my limited experience so take it for what its worth. I have a 300D (with hacked firmware that enabled Flash Compensation) an EX420 and an EX550 (my wife's flash.) For on the camera flash I prefer the 420 simply because I've gotten better results with it. It's a simple flash w/ bounce capabilities. To be fair I have spent a lot of time on the 550 and I'm sure I could tweak it and get good result with it as well. Here's an example using the ex420 for fill. http://www.pbase.com/rkircher/image/44948761 This was taken around mid day on a hike. As you can see the sun is there but w/o the fill flash I'm certain I would have had shadows cast across her face and/or she would have been dark. Granted I'm not as far away as your sample. This example uses both the ex550 on camera and the ex420 as an off camera slave. http://www.pbase.com/rkircher/image/44753957 I this case I had the 550 on camera and was positioned to the left of the subject. I had the 420 the same distance away positioned to the right of the subject. Both flashes were set to bounce off the 9' high white ceiling. Now mind you, I'm no pro and these examples most likely aren't the best but I think they give you some idea of how the flashes perform.

Is there anything newer? Signaturea d y k e s @ p a n i x . c o m Don't blame me. I voted for Gore. |
