RE: Fill flash in low light - balancing natural and flash

Hi all

First off, many thanks to those who offered advice.  Apologies if this reply 
is misplaced, I am subscribed to the digest and it sometimes gets a bit 
confusing as to who replying and whee I should be replying to.

I have one quick question to Tom, who kindly went through quite a bit 
regarding flash:
 I understand that I can manually set the 
 camera 2 stops underexposed and set the flash exposure to 2 
 stops over, 

Well, you could do that, but your shots would have 2 stops too much flash.

I'm confused as to why I'd be exposing incorrectly on this - if I deliberately 
ask the camera to underexpose ambient by two stops,  and after that simply ask 
the flash to take this setting and add two stops to it (at least that's my 
assumption of what +2 flash comp would do), wouldn't that therefore be the 
correct exposure?  The only way I can see this not being the case is if the 
flash TTL exposure takes absolutely no notice of the camera exposure settings, 
and simply works out what it thinks is best, in which case my two stops flash 
compensation would indeed be two stops overexposure.  If anyone can fill me in 
on this (pun not intended) I'd really be very grateful.

I think, on the balance of it, I may just have to go with ambient light as 
it's patently obvious I don't really understand how flash works, and I'd 
rather have slightly soft, grainy pictures (ISO 3200 film) than shots of 
drummers looking like startled bunnies in car headlights.

After having seen how Frank's shots came out, I'd be more than happy with 
anything looking like those (http://www.photo.net/photodb/folder?
folder_id=383331 for those who haven't got the link from the previous 
message).  Unfortunately I have a student lighting engineer who seems to enjoy 
using rear lighting a bit too much for my liking, so there are few (if any) 
kickers lighting the face.  That would be one area where I might just have a 
crack with some standard fill flash - in which case I'll just turn on the 
flash with no compensation and leave it entirely to it's own devices.

Someone suggested a Pz-1 and 500FTZ combo, well I can borrow a Pz-1 but I'm 
stuck with the 400FTZ unfortunately - limited funds mean everything is bought 
used as and where it turns up.  Is it reasonable to suggest that Pentax have 
made this balancing ambient and flash thing unnecessarily difficult to do with 
the MZ series (to recap, I have an MZ-3 and 400FTZ)?

By the way, what's PUG and PAW?

Thanks for all your comments, the battle of the bands is tonight and I've just 
realised I'm down to 2 fast films.  I'll let you know how I get on, and will 
try to get the photos up somewhere.

Cheers

Hi Morgan, many thanks for reply.

 
 I think there's something you're might be missing here...
 
 I shot a band for the second time under very similar circumstances two weeks
 
 ago.  It was my first attempt at using a flash at all, and so I found and 
 read everything I could about it (which BTW is not a lot).
 
 I think you should really look at and try to figure out the Guide Numbers 
 for your flash.  I'm trying to infer information from your post, but it 
 sounds like you want a very high level of detail on the film.  I think you 
 want a.) everything in focus -and- b.) everything well lit.  If you were 
 outside in bright sunlight, this would be no problem.  Just close the 
 aperture down for a big depth-of-field, and you can use all that available 
 light to create a great high-detail negative.
 
 Unfortunately, those are not the circumstances you are working with.
 
 It took me a while to wrap my brain around how the throw distance of my 
 flash works.  Basically, as the aperture opens up, you can use your flash to
 
 expose a greater distance of space.  As your aperture closes down, the total
 
 distance that you can effectively expose with the flash will decrease.
 
 So basically, you could use a relatively fast shutter speed and a small 
 aperture (which would produce big depth of field in normal lighting), but 
 you would get a very short throw distance from your flash.  Thus, your 
 fast shutter, small aperture combination would result in a black background 
 because the aperture wasn't open enough for the flash light.
 
 Likewise, you could open the aperture up and get small depth of field, but 
 everything illuminated.
 
 I'd be willing to bet there's a way to get what you want, but I'm not sure 
 without knowing a.) the distances between you, the subject, and the 
 background -and- b.) the length of your lens.
 
 Hope I could help and not exacerbate the problem...
 
 -m
 


You're partially right in deciphering my question, having reread what I have 
written I didn't perhaps phrase it as well as I could, so I'll try again now.

I really want to do away with flash, and shoot as I would in daylight.  I can 
do this with certain compromises, as in fast film, slow shutter and wide 
aperture.  However, I'd like to improve pretty much all of these but only by 
very slight amounts.  The real problem is shutter speed, as I am getting 
blurred hands etc., and the lighting really is not that great so I am stuck 
with it.  What I want to be able to do is to get as close to being able to 
take the photo WITH THE APERTURE AND SHUTTER AT SETTINGS I WANT, NOT THOSE 
REQUIRED FOR THE CORRECT EXPOSURE (apologies for caps, I don't know how to 
italicise in this email package!).  All I want the flash to do is to bring the 
exposure up to what it should be, thereby using the absolute bare minimum 
amount of flash for my needs.  I have use full auto flash before and it just 
flooded everything - the flash has a guide of 40, it's quite powerful and the 
stage isn't that big.  I also much prefer the effect of stage lighting, and 
would like to keep some idea of this in the photo.

I hope this clarifies, thanks again for your commnets

Matt.

p.s. If I reply in this way, does it fit into the thread structure of PDML 
properly?

The compensation dial always measures compensation from the meter. In other
words, the compensation isn't measured in relation to your settings, it's
set in relation to what the camera sees through the lens.

Basically, shifting to manual mode shifts the compensation calculation from
the ambient meter to the ttl flash meter.

how it works.

2004-03-23 Thread M D Giess
Tom, many thnaks for your reply.

My apologies for labouring the point slightly, but I've another question 
regarding the use of flash.

 
 The compensation dial always measures compensation from the meter. In other
 words, the compensation isn't measured in relation to your settings, it's
 set in relation to what the camera sees through the lens.
 
 Basically, shifting to manual mode shifts the compensation calculation from
 the ambient meter to the ttl flash meter.
 
  

If this is the case, then if I manually set the camera to underexpose by two 
stops and just turn the external flash on with no compensation, would this 
balance the ambient and flash light correctly?  In other words, the ttl flash 
side of things would just use the camera meter and decide, for itself, how 
much flash to use for correct exposure, and the fact I'm underexposing would 
just cause the background to be slightly underexposed and the areas reached by 
the flash would be fine?

I'm a bit unsure of what is meant re. shifting to manual (the second paragraph 
I've quoted), does this mean I can only ever use flash compensation in 
manual?  I was under the impression that, even in aperture priority, when 
flash was used the dual purpose exposure dial became flash compensation (and 
actual exposure compensatio is no longer possible).  Just to clarify, I take 
it now from your comments that I can only use flash compensation in manual 
mode, is this correct?

Sorry to lumber you with so many questions, I hope I'm slowly iterating 
towards actually figuring out what the hell is going on with flash

In a nutshell, yes.

In aperture priority the comp dial affects both ambient and flash.

Yes.

2 things about flash that might help you understand it little better -

- The flash meter is independent and distinct from the ambient (regular)
meter.
- TTL flash works (generally) in the following manner - 

1. Shutter opens.
2. Flash and ttl flash meter are turned on simultaneously.
3. When the ttl meter sees enough light, it turns off the flash.

None of this has anything to do with shutter speed or aperture.

Yes, it does not have a separate dial. I think no, you can use flash

Tom, I set the MZ-5n (same thing as MZ-3 with a slower shutter,
methinks) to Av and lifted the flash. I then played with the exposure
compensation dial and the Aperture-Shutter combination did not move. I
interpret this to mean that exposure compensation in this case (and in
all 4 modes that I tried) affects the flash (except when it thinks the
flash can no longer be limited enough, in which case it closes the
aperture).

I agree with all the rest.

It suited my needs very well.  I was attempting to shoot some uhh, gritty 
photos in low light with the backgrounds dropping off into black.

However, when I was testing the film in better lit conditions, and with a 
flash, I was honestly amazed at the level of gradiation recorded on the 
film.  I was just shooting chairs at various distances away with some 
overhead flourescent light and using my flash at various power settings and 
stepping through the aperture settings.  A lot more detail than I was 
looking for or expected showed up.

But, I also have a (maybe silly) personal preference to use the products of 
smaller companies.  Nanny-nanny-boo-boo Kodak!

Ah-hah, I was always under the impression that  the TTL metering worked by 
recording the amount of light that the film was receiving and then firing 
the flash at a predetermined level to compensate.  But what you're saying is 
that the flash fires until enough light has been received, and then turns 
the flash off.  Is this correct?  I'd really like to know.  I've been 
shooting a ZX-M with (almost uselessly) a 500-FTZ.  Since my ZX-5n is in the 
mail, I've been really looking forward to actually using the TTL flash 
metering and moving beyond shooting the flash manually

 I am confused 
 as to how to set the camera to automatically use flash to 
 supplement low light levels, where I can shoot off aperture 
 priority but underexpose by two stops and use the flash to 
 bump the light back up these two stops.  I can't figure out 
 how to do it, as on the MZ-3 the exposure and flash 
 compensation are done by the same dial.  

I don't believe you can set ambient and flash compensation independently if
you're not in manual mode with this camera.

 If I set the flash 
 compensation dial to take 2 stops off, I assume that the 
 camera will (under aperture priority) simply set the shutter 
 speed for 'correct' exposure and use the flash for fill only, 
 which hard-won experience shows is too slow ('soft' hands and 
 drumsticks etc.).  

Your exposure will be 2 stops underexposed. The ratio of ambient to flash
will depend on the ambient light level, and whether or not that particular
camera decides to go with the lowest safe handheld speed or sets a really
long shutter speed.

 I understand that I can manually set the 
 camera 2 stops underexposed and set the flash exposure to 2 
 stops over, 

Well, you could do that, but your shots would have 2 stops too much flash.

 but there's so much going on I always miss shots 
 if I have to manually balance exposure - poor AF doesn't 
 help, and the shutter speed dial is a pig to turn with the 
 flash mounted (little camera and big
 fingers!)  I would hence like to automate the process, does 
 anyone know if this is possible?

First, are you sure you're allowed to use flash? Are you sure you want to
use flash in this situation? A flash is going to kill all the ambience of
that sort of situation...Studdert does this sort of thing all the time,
maybe he'll chime in here...

Anyway, if you want to proceed, your best option is to drag the shutter. In
manual mode set a fairly long shutter speed, maybe 2 or 3 stops slower than
your safe handholding speed. Set your aperture as wide as you're comfortable
with. Leave your compensation dial at zero. 

OTOH, this might not work very well in this situation because it mostly
works to bring up backgrounds. If your subjects are spotlit the backgrounds
will be almost black.

A common error is to think that you can make up for underexposure with a
little blip of flash. It doesn't really work that way...if you're
underexposing with your ambient settings, you must set your flash comp to
zero. Either your ambient or your flash must be the correct exposure. If
both are under, then you're under. 

Flash/ambient compensation math -

-1 + -1 = -1
-2 +  0 =  0
-2 + +2 = +2

Your exposure is whichever of the 2 is higher.

In order to mix ambient and flash, both have to be pretty close to the
correct exposure. If it's really dark, there just isn't enough ambient to
mix in

high
speed film without flash.  I'm after a bit more quality (i.e. smaller

Hi, Matt,

Well, I think I'll actually type something this time, before sending off my 
sage advice, as it were.  vbg

First, welcome aboard.  I hope you stick around after your flash question is 
answered.  You'll find this forum a quite lively place, and a great source 
of information about Pentaxes, photography in general, and all sorts of 
other things, from Old English Sports Cars to ramps (which thanks to Stan, 
I recently found out is a cross between a leek and a garlic - or something 
like that).  Not that we're supposed to engage in such OT traffic - 
indeed, some are pretty touchy about too much OT.  Whatever...

But, there I go, wandering again...

Oh yeah, flashes.  Well, I don't know much about them.  Tom knows way more, 
so listen to him.  Listen to anyone else who posts on that topic.  Not me.

I was just going to agree with tom when he asked if flash is necessary or 
even desirable?  It does sound like you've shot some with available light.  
What was it about those results that you didn't like?  You mention wanting 
to shoot smaller apertures and slower film speeds.  Why is it that you think 
that you'll get better quality that way?

I'm not trying to take you to task here.  It may be simply that you want a 
different look, just to see how it looks.  Maybe you feel you've done all 
you can do with available light.  And, that's fair enough.  I guess I just 
wonder about your better quality comment.

As tom said, it may be that a flash will not be appreciated.  I recently 
shot a band with available light.  I told them that I'd be using available 
light, to which they replied, Good, because we wouldn't really want a flash 
to be used anyway.  The music they play is quiet and comtemplative - they 
do a lot of improvising, so they need to be able to hear each other, and 
concentrate on the music.  A flash would have been very disruptive.

OTOH, I've shot several shows of a friend's Loud Rock Band.  They didn't 
care if I used flash - in fact, at one point I was using a 19mm lens, about 
18 inches from them, and they didn't even notice.  It was fine with them, 
and they liked the results (even if I didn't).

If you've already considered all of these things, then I apologize for 
sticking my nose in.  Simply do as the rest of the list does, and ignore me. 
 vbg

Whatever you decide to do, I hope it turns out, and you should post the 
results so we can see.  Here's my last shoot with the quiet band, my first 
shoot at available light in these circumstances - not great stuff to be 
sure, but better than I thought it might turn out:

http://www.photo.net/photodb/folder?folder_id=383331

BTW, do you know about PUG and PAW?  I don't know how long you've been 
lurking (if at all), so you may be up to speed on this stuff.  If not, we 
can fill you in if you're interested.

Thanks for your indulgence on a long and rambling post - I'm amazed that you 
actually read this far down!!  vbg

That's very interesting Frank, but what do you think Oppenheimer would say
about this flash issue?

Hi all

This is my first post, so hello to everyone.

I have a question regarding flash I'd like to ask.  I am taking 
photos of a
band in quite a small, dark venue and I usually just use a fast lens 
with high
speed film without flash.  I'm after a bit more quality (i.e. smaller 
aperture
and slower film) and would like to experiment a bit, but 
unfortunately I have
to print a few photos for band members so I can't mess up too badly!

I have got an MZ-3 with a 400FTZ flash and when I use flash in normal
situations I simply shoot in aperture priority and let the camera 
work out the
shutter and TTL flash, and if I only want a bit of fill flash I take 
1 to 2
stops off using the Exposure Compensation dial which doubles as the 
flash
compensation dial.

The problem I am facing is using flash to supplement low light 
levels, in
effect how to balance natural light and flash.  I have always 
considered fill
flash as something that simply lights up a few shadows, where the 
exposure
would be correct without the flash but that little burst just puts a 
bit more
light where the scene is a bit dark.  I am confused as to how to set the
camera to automatically use flash to supplement low light levels, 
where I can
shoot off aperture priority but underexpose by two stops and use the 
flash to
bump the light back up these two stops.  I can't figure out how to do 
it, as
on the MZ-3 the exposure and flash compensation are done by the same 
dial.  If
I set the flash compensation dial to take 2 stops off, I assume that the
camera will (under aperture priority) simply set the shutter speed
for 'correct' exposure and use the flash for fill only, which hard-won
experience shows is too slow ('soft' hands and drumsticks etc.).  I 
understand
that I can manually set the camera 2 stops underexposed and set the 
flash
exposure to 2 stops over, but there's so much going on I always miss 
shots if
I have to manually balance exposure - poor AF doesn't help, and the 
shutter
speed dial is a pig to turn with the flash mounted (little camera and 
big
fingers!)  I would hence like to automate the process, does anyone 
know if
this is possible?

As you can probably see, I'm quite new to the flash area, any advice or
comments would be greatly appreciated.
Many thanks

Matt
