Hey Guys.
Just a question I need help with. :help: :bonk:
But when im shooting in clubs or parties, I have noticed that sometimes there is a long period that my camera stays busy for, before i can take the next photo.
What causes this.
Is it when I have alot of photos stored so it slows down.
Is it the battery getting low?
Its very confusing and when it comes to a "capture the moment" picture, often i miss out on good shots because my camera status is busy.
Please Help Guys :D
Thanks Very Much
Gary
 
i think, its the memory buffer getting filled up and not emtying to the card fast enough

im probs totaly wrong
 
No, in clubs I dont use a flash
The internal one is good enough for what i need.
The main reason actually being is you get the drunk idiots bashing into you so I dont want it snapped off
lol
Any ideas guys lol

Noise reduction does it too on long exposures as I found out the other night doing my first star trail shot and it was busy for 10 minutes!
 
If I remember right the in camera noise reduction runs as long as the exposure.
 
sounds like noise reduction is on... pointless to do it in camera when the canon software can do it for you after jsut as well.
 
On the 400D IIRC, the noise reduction process only kicks in if the exposure time is 1 second or longer, so it's unlikely to be the cause.

Post up a photo with the exif intact and lets have a look at what is going on. What sort of cards are you using?
 
Does it happen when you've taken several shots in quick succession? It could be that the internal buffer is full so you can't take any more shots until it's written data to the card. I think that's what #13 was meaning but maybe the point about several shots wasn't clear?
 
What make/model of memory card are you using ?

I have a couple of Sandisk Extreme III cards which are fine, I can run a 7-8 second burst at 6fps on the 40D before it slows me down. However, the other cards I have can only handle about 4-5 seconds, as they're not "as fast".

I wasn't aware that in in camera noise reduction added any additional load on the buffer, but thinking about it I guess it must.

EXIF data is the information embedded in a jpeg file which gives details such as shutter speed, aperture etc...

Do you shoot Raws at 3 or 4fps?

Richard.
 
Maybe a re-word is needed?

How long a pause do you leave between shots? If you take just one shot does the camera stay busy for a while or does it only go busy when you've taken several shots in one go?

I think that is your problem. You didn't make yourself very clear though, and it looked like you were saying you didn't use flash at all in clubs. But having just checked one of your nightclub shots exif (THIS one), you did in fact use flash :thinking: I presume it was the cameras on board flash? This will definitely slow you down. HTH.
 
Ok, then a faster card will improve things slightly but the delay will still happen. The camera has an internal buffer but once that's full it has to write the data out to the card before it can take any more shots. Once space becomes available in the internal buffer you can take another shot but you'll immediately fill it up again and writing shots to the card is fairly slow really as you've experienced. Ultimately the problem is that you can take shots faster than the camera can write them to the card.

Shooting jpeg will improve the situation as the files are smaller, on the 400D you can get about 11 frames in raw and 27 frames in jpeg before the buffer fills up but those figures are under ideal conditions. High ISO (more noise) or lots of detail in the frame means more data to be stored thus reducing the max number of frames the buffer can hold.

thanks pxl8
 
My 400d suffers from the exact same issue when using the built on flash. I am using a 4gb sandisk extream iv.

When trying to capture shots around 100 -150 it can sit at busy just before the shutter click and after.

Easy solution. wack a external flash gun on. Solved my issues and now allows better lighting when shooting with the 400.

If your fearful of it getting snapped off, get a bracket that will allow the flash gun to sit parallel to the body. They cost about £25+ but give u a two hands on aproch to the camera and not easily damaged by drunken Yobs who want to touch your camera....Now all you have to worrie about is drink being spilt on it

I shoot in clubs every weekend, always have an external flash on. If you keep your wits about you it won't ever get snapped off.

Not sure you spotted Jo's post.
I have the 400d and when using the internal flash there are long busy times between shots.
 
Yeah it is all down to the internal flash, which really doesn't light many subjects adequately in clubs. Get your external on!
