  1. Yes, 50cm is close, but you mention Bruce Gilden's latest work. I think he photographs quite close, less than 50cm (even with a 50mm lens). Yeah, I know I need to look at the guide number. And I know how to use a manual flash. What I'm looking to understand is: if I get a TTL flash compatible with my M6, will it accommodate for all the situations I encounter, which include taking photos at night up-close (50cm) and from afar (10m). If a TTL flash does not fully cover these types of situations, then I don't want to get one.
  2. Ok, thanks for en lighting me. - And let’s say I take photos in total darkness with my M6 TTL. Will the scene be too dark for the TTL to be effective? - Then in the same total darkness setup, I could be 50cm from my subject, or 10m away from it. Flash output clearly shouldn’t be the same power. What’s happening here? Will the flash overexpose at 50cm away, and underexpose 10m away? - and how does the TTL behave when taking photo of a subject in the shadow of a strong light in the background? If the metering read the shadow it is likely to trigger the flash? And if it takes its reading from the strong light, is it likely no to trigger the flash?
  3. Ok. Am sorry. Sorry to fail understanding the situation here. If you still have the patience to answer, then I have questions that would hopefully help me understand how to improve my flash photography, or at least make it less cumbersome than having to set my flash manually. Does the distance from flash to subject have any relevance in flash photography? I veilieve it does, as light decreases as it « travels » towards the subject. If yes, then how is it taken into account when I use my Leica SF 24D flash with my M6? Hopefully this will make it easier for me to understand..
  4. I feel like I can answer my initial questions now. Yes. Kind of yes. No, because TTL metering is only about light measurement, not distance measurement. No. Conclusion: TTL is often regarded as a useful feature. But I find it quite useless because distance is not taken into account in deciding the amount of light to be output by the flash (unless you are in the optimum range of your flash, which, I guess, must be around 2m)
  5. I feel they weren't the same questions. You were two to reply, not several.. You don't understand my question. I'm asking if the flash will need a much more powerful output, not if my flash can or cannot get the same exposure. Well, no, I don't remember, and never knew. Hence me asking... Thanks for the lecture. I knew that actually. Thanks for repeating. I wasn't sure if I understood. Yes, I came to that conclusion too. About five years ago. Thanks for the lecture.
  6. So even the flash doesn't take distance into account? I thought modern flash units did... I feel it's important to vary the flash output depending on the subject distance. For example, let's say I take a photo of a wall at night. I take a photo with the flash at 50cm distance. If I want to get the wall to look the same brightness 20m away, my flash will have to output a much higher strobe, no? I'm looking for a way to address this issue when I take photos at night..
  7. Thanks Dieter for the explanations! So, I understand that the distance is indeed taken into account, but by the flash itself, not the camera.. I wonder how precise the sensor is.. It would have been good if the flash output could vary depending on the focusing distance set on the lens (focusing distance is already mechanically transmitted from the lens to the rangefinder component, so why not using it to tune the flash output?). So, to conclude, I always assumed TTL on the M6 was a really good thing to have, but I now realise that it's pretty useless to me.. Many thanks for your help on this!
  8. Part of the explanation you first provided is difficult to understand for me (im technically savvy only to a certain point). Maybe I can try and clarify my question. Flash output should take into account the distance of the subject from the flash. Does the M6 take this distance into account when it sends the signal to the hot-shoe?
  9. Thanks so much for your reply. So, if I understand we’ll, the TTL system on my M6 will NOT take distance into account? This means it will send the same light output whether my subject is 20cm or 20m away?
  10. Hi, I struggle to understand what's so good about flash and TTL, particularly on my M6. From what I understand, TTL tell the flash how much light to burst depending on the amount of light measured by the metering system. Am I correct? But then, what about distance? If the metering reads the subject is mildly lit, it'll tell the flash to burst a mild amount of light, right? But what happens if the subject is really far? The burst of light will not lit the subject enough, right? Does the M6 (and other camera TTL systems) take into account the focusing distance?
