View Full Version : External Flash on 300D - Trying to get this down pat

OK, as you can see from my sig line, still shooting with my 300D. Hey, it still works great and has another year warranty, so why switch now?

Anyway, equipment choice aside, I only just recently finally purchased an E-TTL (II) compatible flash unit (the Sunpak listed in the sig line). Prior to now, I've been using an older Vivitar manual flash (with a Wien hotshoe saver - natch), shooting in Manual at 1/100 or 1/200 and altering aperature to match. Shooting in Raw helped guarantee I could recover any shots where I didn't hit the aperture just right.

I've shot a few indoor events (non-paid, pleasure type stuff) with the flash. The first one was a large kids group thing in church. For the most part, just put it in "P" mode, turned on the flash and 90% of them came out just perfect.

Next time I tried, at an indoor party for my daughter, 90% of them came out just too dark. Sadly, I was shooting JPG so I had to toss a few decent shots. Once I got home, I did a post-mortem and read through the EOS Flash Bible again to try to figure out what I was doing wrong. I thought I pretty well had it nailed with the following strategy and tested it at the house:

"P" mode, center focus point only, aim focus point at desired neutral tone (typically a face or other midtoned object), hit the FEL button to pop the flash, recompose, half-shutter to focus, then fire. Seemed to work great at the house...... then I read the manual for my camera, which recommended:

Aim at subject, half-press shutter to focus and keep holding it. Re-aim as necessary for flash, press and hold the FEL button (now you're holding both the FEL and shutter buttons down), re-aim again and fully press the shutter button. Besides being rather cumbersome to perform, I seemed to notice that the lens wanted to re-focus when I hit the FEL button. At home, the shots I tried this with (at another event) were out of focus.

OK, after a long explanation, remember that this is a 300D, which has a slightly different flash program than even it's more capable 10D sibling and others after it. Anyone that used an E-TTL flash with a 300D for a while with good results want to clue me in on what I should be doing? I have another event tomorrow (again, unpaid, but slightly more important than the previous events) and I'd really like to avoid a lot of post-processing of dark shots or, worse yet, a lot of deleting of badly focused ones.

Sorry for the long-winded question. :-)

I don't think holding the FEL (*) button does anything, just push it. It doesn't control the lens unless CF4-1 is turned on. Make sure you use FEC and watch your histogram.

The 300D has neither custom functions nor flash exposure compensation (FEC). FEC is pretty crucial, and someone at Canon should be dope-slapped for designing a camera without it. And unfortunately, your Sunpak flash doesn't have FEC either.

So your options are:
1) Buy a flash unit with FEC, such as the 430EX, 550EX, 580EX or possibly a Sigma EF-500 DG Super (or 530).
2) Install one of the firmware hacks on your 300D to enable FEC.

As for using Flash Exposure Lock (FEL), it's basically a way to use partial metering for your flash exposure. Aim where you want to meter, push the * button, then recompose, focus and take your shot within 16 seconds.

Oh wow, I haven't had a 300D for so long I forgot those things. Without FEC you're pretty hosed. The firmware hack is essential.

Thanks for the replies. I made it through the event using the method Curtis suggested (punch FEL, shoot within 16 seconds). That's what has been working more often than not for me so far. In reading the confusing (and conflicting) instructions in the 300D manual is what had been throwing me off.

I had a few underexposures (probably due to small targets throwing the metering off a bit), but was shooting RAW and pulled them all out of the dark pretty easily. The only close call was one I had to bring up 3 full stops, but I had just come inside and was still running ISO 200.

I recently did install the hack (again), but haven't played with FEC yet. I figured today wasn't an opportune time to fiddle around with settings. :-)

The lighting in our church sanctuary is fun enough, as it is. It's a new building and they were convinced (and probably rightly so) to go with flourescent lighting in the traditional fixtures. Mix that with a nice sunny day outside, lots of foliage outside some of the windows, and a flash, and you have lots of conflicting white balance issues. I feel for those shooting in basketball/hockey stadiums.

Gel your flash to match the prevailing light source. If it's too mixed just tell the customers you used your black and white digital camera ;)

Good idea. Actually, once I got into a groove, fixing the WB was pretty easy in RAW.

Anyways, it wasn't a business shoot. I've more or less gotten out of that end of the deal. Just shoot for pleasure now. Lots less pressure.
