  • Geysir HDR

    Whilst we were at Geysir this scene took my fancy, but it obviously had a wide dynamic range that the camera couldn't cope with, so as I had the tripod with me I decided to take a sequence of 6 separated by 2/3 EV. I've processed them in LR2 and and produced the HDR and tonemapped image using Photomatix.

    Re: Geysir HDR

    Hi Stephen, very nice! As E-P1 has 3 fps., 6 consecutive shots means probably 2 seconds. So the river flows for that elapsed time... Is this a correct inference?

    Don't you have some other shots? If possible, I want to have a closer look at the river and the volcano (spa) steam/smoke. And/or if you also took some more shots with different AEB width, hopefully you upload some more --- of course, only when/if you do not mind.

    How was the wind on that day, strong or mild? I'm very much interested in this type of HDR as one more way of giving a movement to a still photo.

    One more. Have you also taken a shot with a slow shutter speed (not HDR). I would be glad if I can compare the two kinds of means of showing movement. I know you said the dynamic range was too big for the camera sensor to cope with but only when you additionally took ordinary slow shutter speed version for test purposes...

    P.S. Just disregard this, if it is not convenient with you. I know I have just too much interests and curiosity.

      Very clever and beautiful. It would make a lovely print.

        An amazing photo Stephen! Was it early morning, as in sunrise! Did you use a polarizing lens or not? If not, would the sensor cope better or not?

          Good question about the polariser. I don't think it would make any difference to the dynamic range, though. I think almost any camera would have problems capturing the detail in the dark shadows while keeping the brightness of the sun under control.

            Thanks Jocelyn, I'd agree with Ian that a polarizing filter would make no difference in this situation, frankly I rarely use one anyway, and rarely carry one unless I know I'll need it to kill reflections etc.

            As for the time of day, the picture was taken at approx 14.50. At this time of year in Iceland the sun doesn't rise until 11.00 and goes down just after 16.00. It never gets very high in the sky then, but it does give you very warm glows for a good deal of the 5 or so hours its there

              Julia just pointed out to me that it might have been useful to cut down on glare. This is something that definitely works when wearing polarised sunglasses but I'm not sure who much benefit it would give to a camera.

                I suppose that's possible, but in the context of what Jocelyn was meaning, its not something I would be normally rushing to use. However, what would have worked are ND grad filters, again though they give a different result to HDR and tonemapping

                  Actually you are not correct here Yoshi The six images used were not taken using the multiple expsure setting, so not at 3fps. Each exposure was adjusted manually using the exposure compensation function, so infact the time lapse between the first and last exposure was much more than 2 seconds.

                  Unfortunately I didn't take any more of this particular scene.

                  I'm not really sure of the mechanics of a program such as Photomatix when it comes to blending exposures that include some movement. The fact is that water and in this case steam do not seem to be blurred as perhaps you would expect. The pictures were not taken though in order to show movement so I'm not really sure what you are asking me

                    Re: Geysir HDR

                    Many thanks, Stephen, for more explanation. When i posted my questions, I assumed that you used AE bracketing twice in order to get the 6 shots.

                    The elapsed time between the first shot and the 6th shot is then much longer than 2 sec. yet the river on your pic is not that white which is often the case when a single shot with a long shutter speed of say 2 sec. is chosen.

                    This is exactly I was wishing to see on a pic and I found it on this pic so I was simply delighted to see it and hoped to look at some more related shots.
                    Definitely not intended to find "blur" or whatever in any sense. As long as there are some time elapsed between shots, and also if there is something moving in the frame, it's "movement" in this context.

                    I do understand that you used HDR for the purpose of coping with wider dynamic range and not intended to show "movement".

                    I struggled with Photmatix before and stopped using it since then but maybe ...

                    thanks again.

                      This is the first time I have used it in a long time. Its one of those things that there was a craze for a few years ago maybe when I bought it, but I kind of lost interest in it when everyone was using it and frankly it was a bit 'over done'. If I'm honest I struggle to understand what all the controls are for, but I play around with the sliders in the tonemapping module until I get something I like. Leaving things on the default settings often lead to an 'overcooked' image so I try to turn things down a bit. If you have a copy I definitely think its worth giving it a go again, but you have to give it some of your own input.

                        With Photomatix I think the user needs to know the software well to get the best out of it, and control the effect, true of all software really.
                        I am very much on a learning curve myself.
                        I have not myself found movement to change things much if the ghost artefact reduction box is ticked, there are two levels of strength normal & high. I have not yet experimented with the box un-ticked so cannot comment on what happens.

                        These days I routinely expose three shots with HDR in mind, both hand held and with a tripod, I feel it gives that extra something even to images within the cameras dynamic range.
                        The over cooked look can work on some images but a more supple but strong approach I personally like best.

                        Insistently depending on the version you are using, an HDR image can be made directly from your RAW files using Photomatix.

                        Love the picture by the way Stephen, I did wonder if one more exposure just for the sun would have given a little detail in that one small burnt out area.

                          Thanks Patrick and yes I agree, maybe one more shot would have helped. I'm wondering if I can do it manually in LR and add it as a 7th image..........think I'll give it a go

                            And? have you? Beautiful image, by the way. Like Patrick, I'm a fan of HDR, but only if it's done subtly. I can't stand those bright garish shots... really doesn't float my boat

                              Hi Caz, yes I did have a go, but I couldn't get a significant amount of detail back into the sun area, so I didn't bother posting it. Glad you like it though and thanks for the interest.
