Auto Exposure Bracketing

Don't know if this has been mentioned before, but AEB would really be useful if incorporated into the M8 firmware,

very useful for scenic and landscape type shots, ..without movement (on the tripod) due to manual disturbance.

 

What do you think?

It's interesting you guys brought it up before, ..with no comments or progress. It was brought up this morning at an informal Leica Users Group meeting

(I attend every now and then), and all agreed they would love to have this addition.

 

Hands all went up! :)

Definitely yes. I have a Hasselblad Xpan (film) with this feature and it can be very useful for difficult exposure situations. And no tripod is really necessary unless the situation otherwise calls for one. Just three rapid clicks in a row, with auto motor driven film advance and recocking of shutter. Even easier in digital than film.

 

Question for the experts: could this be done with a software update, which might be loaded by M8.2 owner without return to factory?

Interesting thread. My Contax RX many years ago was the first camera I encountered with autobracketing. It was useful when shooting slide, in those pre-photoshop days. That brings me to two questions...

 

1. Now that we have RAW is it really necessary?

2. Does anyone actually like the eyeball-itching shortbread tin lid unreality of HDR imagery?

[Disclaimer: I am not replying to this claiming be an expert....]

 

Yes, of course, the M8 can already run in continuous mode, so it would be simple to program the camera to fire multiple shots each with different EV values. The user would want to specify in an extended SET menu how many shots to take (say, 3, 5, 7), the starting EV (-1, -2, -3) and the EV incremement (0.3, 0.7, 1.0), for example, with an overall limit of +/- 3 EV.

 

This could all be done in firmware though I expect you would have to buy the new M8.7 to get the new function...

For Bill Palmer, with a bemused expression on my face, arising from my illiteracy in the slang of somewhere (I live in US)"

 

"2. Does anyone actually like the eyeball-itching shortbread tin lid unreality of HDR imagery?"

 

WHAT does this mean?

 

Thanks for the fun, and I await eagerly.

I want it for my M8 Classic! Remember, I was one of the pioneers to raise the point. This AEB feature, in combination with delayed shutter recock, would make the M8 a killer.

They look crap - or at least the ones I've stumbled across do - with the sort of compressed dynamics, and unatural colours you see on some biscuit tins. Actually, I wouldn't have thought of the pastel colours on a biscuit tin as an analogy, thanks Bill.

 

Maybe I've been unlucky with the ones I've seen. Perhaps they've been prepared by people who don't know how to properly exploit the technique.

That's it exactly.

 

Again, like Steve, maybe I have been unfortunate, but I have yet to see an HDR image that does anything other than make my teeth itch. I suspect the ones I have seen that have not had that effect have been the ones where the effect is subtle enough not to notice. In every other respect I think HDR belongs with the blurred sea/single rock/tobacco grad/un-natural hue landscape shots so beloved of certain photo magazines.

I would agree as a general rule, but I have actually seen some HDR images that looked pretty darn good. Specifically, I recall some shots done on a Yosemite seminar that Guy and Jack organized for M8 users. They picked up just enough shadow detail to really make the images pop. Normally, I think people who use the HDR technique far overdo the application and end up with too much spread in exposure latitude.

Again, well said. I am happy to concede that the examples I have seen fall into that camp.

Back to bracketing. The question has been put: Do we need it now when we have RAW? Meaning, I presume, now when we have Photoshop.

 

Yes. No amount of post-processing will save highlights that have been burnt out by too much exposure. There is of course also a point where shadow detail is irrevocably lost, though this is less of a problem.

 

The only alternatives to bracketing are:

 

• Minus-expose to save the highlights no matter what, and use Photoshop after the fact to lift the gloom. But you do inevitably pay in a shorter tonal scale.

 

• Get a hand-held incident-light meter and learn to use it.

Lars, thank you for the informative answer. That makes complete sense.

Hey Lars,

• Get a hand-held incident-light meter and learn to use it.
I also use (some times, when really needed) a 1° spot meter.

Despite this, i would like to have AEB function in my M8s, because i'm a lasy person.

 

What i also would like very much, is a time regulator in the "Leica Digital Capture" software.

You know, the one you could use to shoot automatically i.e. every 5 sec. or every hour.
