I'm attaching a couple of pictures showing what I've been doing with it so far. They're not 'arty' like the ones from Stephen. What I did was to take a series of shots a different exposures then i merged them to create a .hdr image which I then tone-mapped aiming to bring out the details of both the sky AND the dark areas. The exposures of the original shots ranged from under-exposed to over-exposed .. with reading taken a) from the sky and b) from the darkest areas -then shooting a short series with 1.5 stop intervals between shots. What I did *wrong* in the shot of the yew tree was to take too long over the series of shots so the final image shows the movenment in the clouds 'cos I'd underestimated the breeze. The one in the graveyard didn't have so much cloud movement - but it wouldn't have been possible to get so much sky detail AND church detail if I hadn't shot a series and created the HDR image and the tone mapped it. Hope that all makes sense.. I'm not exactly techie, nor am I a very experienced photographer. Two images attached - content is nothing special but they show something of how you can get extra detail in light/dark areas of the same image Pol |

I've bought the plugin so mine is registered therefore there are no longer any watermarks on my saved images. Pol |

Sorry Polly My mind is going I had better correct that. I looked at the price and thought I would just play for now.

S'ok. I have 'senior moments' myself but don't tell anyone. Aye, I agree it's worth playing about with it for a while before you decide whether or not to buy it. It works out at about £48.18 with the VAT added so be sure you're likely to want to use it - or maybe share the use of it with other members of the family who use the same PC and/or laptop. Pol |

Thanks for posting those. The church pic really does show how much extra detail you can get. I am having a bit of a play with D-Lighting in Nikon Capture and am amazed at the amount of shadow detail that it is capable of bringing out. Don |

The merged image, seen on the right, was then opened in CS2 then tone-mapped with the photomatix plugin to produce the final image which I'd attached to my earlier posting. As I said - the content isn't anything special but the opportunity had presented itself for me to set up in a quiet corner where I could try out a series of shots for experimenting with .hdr and tone-mapping. I used spot metering - took a reading from the sky and a second reading from the darker wall - then took 5 shots with one stop intervals (as seen in the attached source image) Dimensions are approx. 1000 x 735 pixels as that was necessary to show the full CS2 interface and source images.

Firstly, let me apologise to Don for hijacking his thread, these things are sometimes like chinese whispers and the subject seems to end up totally different to how it started out
Pol, I seem to be having a problem with the way in which CS2 is blending your images in the example you have shown. The sky in the blended preview still seems burnt out in places, whilst the the shot taken at 0.0EV seems to look pretty good in the sky area. In fact the preview looks much like the one in the +2.0EV. So whats going on here? Could it be modified by switching off one of the images at the extremes for example. The sky area in the example you posted earlier in the thread seems much better to me, was that produced in the same way or is that the result of applying tonemapping to the resulting HDR image. If so I would argue that some of the tone we see in that other example is the grey infill that the plugin seems to apply to blown highlights. |

The graveyard image is tone-mapped - that's how I retrieved the blue area above the roof..... after all, the components are there in the .hdr they are retrievable. The Yew tree and churchyard were my first and only experiments at shooting a specific series (apart from that gate latch series) so I can't really claim to be any sort of expert. I think maybe what I have concluded is that 3 shots at 1.5 or 2 stop intervals would probably be enough though - I reckon that should cover sufficient range. I think I probably overdid it with 5 and might be better trying bracketing another time. What I actually did was started shooting with the shutter speed set at the reading from the sky - then worked down in 1 stop intervals until I reached the reading from the dark wall. I suppose I could also convert the RAWs to 8bit jpgs then see what happenes if I create the hdr in the Photomatix basic freeware..... though the picci is just so boring I'm not sure if it's worth the bother. I'd rather try to have another attempt only somewhere and something more interesting. Pol |
