I think it probably does look a bit more realistic. The stone might have been a fraction darker.

So - what do you reckon, Nigel? An improved HDR from several images, re-processing of a single image - or something else? Is it realistic enough for you?

Technically realistic rendition? I don't know. I think it might be a little better. You folks can guess for yourselves how it was produced.

and a 100% crop ..........

Better, worse or just different? I quite like it.

I think LR/Enfuse is actually quite good. It can do either HDR or focus stacking. I'm sure it can produce better results than I have seen so far - especially if I don't try (too much) to "improve" the image afterwards.

Up to press I have only played with it. Maybe I need to spend more serious time with it to get the best from it.

I think I've learned quite a bit in this thread - and thanks to everyone who has contributed to that. Some of that is really re-learning stuff that I thought I knew anyway - such as shooting RAW and exposing to just avoid clipping highlights. It seems to work quite well even for fairly extreme subjects like stained glass windows in a church and landscapes with fluffy white clouds (which I should use ND grads for anyway).

I'm looking forward to seeing what the judge in my club comp is going to make of the stained glass HDR print I submitted. Maybe I should barrack if he doesn't mark it down.

Nope, just the reverse. As I said of the last image, all I've done is lift the shadows & blacks so that the stone isn't completely black - and sharpen a bit. Other than that, it's exactly as a JPEG out of camera would have been.

In my book, the crop from the original HDR is ....... awful. I can't believe that I put that image into a photo club comp.

Nigel, this is a crop from the first HDR image at the start of the thread.

You don't really think that's better than the crop from the single image immediately above, do you?

Nigel - I agree with what you say, to an extent, about making selections and masking not being so simple. It would only be worth it if I regarded the stonework as being an important element of the photo. In a club comp, it's likely that the image would be marked down if the stonework was completely black with no detail.

Bearing that in mind, I have here just taken the single image (0.5sec exp) and lifted the shadows and blacks in Lightroom & added some sharpening.

I'm not sure I can do much better with a single image. FWIW, I definitely prefer it to the first image in the thread. I remain unconvinced of the benefits of HDR software.

The very last post looks a bleached but the potential for rich saturation is there, it just needs a tweak on the slider in PS to bring down the highlights and enrich those lovely reds and blues.
Yep, I did try that. No matter what I do, it leaves the large blue area in the left hand pane looking purple.

Taking two exposures and bleeding them together (by any method) produces a HDR image.
I am coming to think that the advantage of the Smeggypants cut & paste using two images approach, is that you have full control of the output - which isn't the case if you use HDR software (even the simple LR/Enfuse plugin in Lightroom).

FWIW, this is the default output of a HDR produced by LR/Enfuse from the 0.5sec image and one three stops lighter (4sec).

I think HDR & LR/Enfuse just went on the back burner again. It doesn't seem to have anything to offer for this kind of image. I think now, for this kind of image, Smeggypants suggestion of using two images - one for the glass and the other for the stonework and then doing a cut and paste job might work best.
