On 2013-06-23 19:21:44 -0700, "Dudley Hanks" said: Ok, now that I've got that communications glitch straightened out, I think I was able to put together the image I was shooting for. http://www.blind-apertures.ca/pics/Landscape.jpg It's a quasiHDR image of the river valley, here in Edmonton. What do you mean by "quasiHDR"? Just that it's an attempt to compress a dynamic range my cam couldn't capture by using multiple exposures and merging them using the exposure merge feature in Elements. There is more to HDR than merging an exposure bracket set. Stacking those exposures will give you a blend. However, the dynamic range is not going to be expanded as evidenced in your result image. Five shots, ranging from -2 to +2 stops and combined using Elements 11. That is a start, but just combining the bracket set with PSE11 does not make it any sort of HDR. Your result is bland and no better than the WB problem shot, HDR doesn't really seem to be needed. If you are going to process the 5 shot bracket as an HDR you will need at a minimum the Photoshop "merge to HDR" feature or dedicated HDR software such as Photomatix or NIK HDR Efex Pro2. It's my understanding that HDR is simply a term used to describe the process used to compress a highly dynamic scene into colours / tones that can be reproduced in a single image. Am I missing something in this definition? An HDR image is the result of processing an HDR exposure bracket stack to capture a wider dynamic range than you would obtain in a "normal" exposure. Together with the merge, there are also tone-mapping, tonal contrast, saturation, and other tweeks to make it truly work right. If you care to post the 5 shots from your HDR bracket and I would be happy to see what I can get from them. This pic is just the end result of an exercise I undertook to help me understand an issue I'm systematically working through: to develop a process by which I can achieve results similar to those of a sighted photographer in settings whereby the lighting range exceeds the capability of my camera to capture it, and in which it is impractical to use an artificial means to smooth out the lighting curve (i.e. flash, reflectors, etc). ...and certainly true HDR processing can give you that type of solution. I suggest you get a trial of Photomatix or NIK HDR Efex Pro 2, so you can see what you can really do with those bracketed shots. More importantly HDR software can do a decent job of doing single exposure tone-mapping, which might be all you need. I understand that a few adjustments in Camera Raw to the shadows, highlights, whites, and blacks sliders, to name only a few, can do the same thing, Not quite. but it wouldn't tell me much about what kind of results can be achieved with the exposure merge feature. Exposure merge on its own is not the answer. Again, exposure merge is not HDR. It's not an attempt to produce a completed image for the sake of the image, just another step in the journey... After I feel more comfortable doing an exposure merge, I'll devote more time and energy to producing an actual HDR image. Take Care, Dudley Just to give you an idea of a single exposure tone map treatment here is your original compare with the result after a run through NIK HDR Efex Pro 2 for tone mapping, no exposure brackets used. https://dl.dropbox.com/u/1295663/Fil...enshot_241.jpg -- Regards, Savageduck Thanks, SD, I'm working on a script that will (hopefully) help me pixel peep a bit and do a thorough comparison of differently processed images. This will be a good test to see how much of the difference it can detect. Take Care, Dudley |

Something between that and your original bland and over-exposed image, if possible. -- Cheers, David Web: http://www.satsignal.eu Thanks, David. I think your comment that the original was over-exposed is the key to my problem. I just did a straight five shot, plus or minus two stops, without checking to see if I had captured an appropriate range. As it turns out, I didn't capture a range sufficiently exposed to eliminate all of the clipping. When I try it the next time, I'll bring along my netbook and tether it to the cam so I can get a bit more info on how the bracket set gets exposed. Hopefully, it will help me get in the right exposure ballpark. Take Care, Dudley |

Something between that and your original bland and over-exposed image, if possible. Well, the OP said he was looking for HDR, so I thought I'd do it strongly rather than subtly. If I was "forced" to do HDR, I would probably do it more like this: http://sandman.net/files/dudley_hanks2.jpg -- Sandman[.net] |

Perhaps less colour saturation, and a little less dynamic range? -- Cheers, David Web: http://www.satsignal.eu |

Create a new layer Filter! blur ! average levels layer Center dropper, turns the average neutal gray. Delete the blurred layer. Make other adjustments from there. -- PeterN |

It does not shange the underlying layer itself. Only how it appears. Try it. the purpose for the blurred layer is to easily set levels, or curves, to neutral gray. Seriously, try it. -- PeterN |
