I have tried to concentrate on getting the glass as I think it should be and pretty much ignoring the stonework.

This is a crop from the bottom of that image.

How are we doing? Any better?

The TIFF produced by LR/Enfuse was too dark. Bringing up the shadows; reducing the reds a bit, adding +20 contrast in LR, reducing saturation to -20 but no other processing generates this image.

I certainly prefer this to the over-cooked version. I'm not sure whether I prefer it to the second image above (single shot at 0.5sec).
I don't understand why there's a large area of purple in the bottom left corner of the window - it's blue out of the camera (preview images). I wish I could remember what it really looked like.
I'm still not sure what I think about using LR-Enfuse. It seems that most of the time, even in quite extreme situations, you can get a decent result from a single image, providing you don't blow the highlights.
I'll have a ponder .......

A quick and dirty conversion of one of the set used for input to the HDR processing, taken at f/8 0.5sec ISO100.
With a bit of work ...... who knows. Some of the blues in the stained glass are better, rather than the purple version in the HDR.

I took 8 shots at f/8, ISO 100 with shutter speeds ranging from 1/15sec to 8 secs, using a Pentax K30 and DA55-300mm zoom (at 87.5mm). I used Lightroom, with a plug-in LR/Enfuse to convert/merge the 8 RAWs into a 64bit TIFF just over 120MB. After a bit more twiddling and cropping in Lightroom, this came out of the mill.

I'm quite happy with the result. Thoughts?

The method I've used with the 55-300mm is to take lots of shots of a distant non-moving subject at each AF setting, average the RAW (or JPEG) file sizes for each AF setting and then pick the setting that gives you the biggest file size - and hence the most detail.
How do others do this?

Andrew, that is fantastic - you have given me some great ides of things to focus on (points of interest) for my next series of images from the north Surrey / South Croydon borders!

Say for example I had been commissioned by, say, the 'Kenley & Caterham Promotion Council', to photograph the countryside for a local magazine illustrating the pleasures on offer for leisure & dog walkers if they buy in the area. Does that change our assessment of their effectiveness?
Sorry, but the photos do not seem to work at all for that specific purpose.

I have been trying for years, with limited success, to improve my photography by concentrating more on trying to make stronger images. I have found a number of books helpful here, such as Bryan Peterson's book on seeing creatively. Joining a photography club has helped me too, I think.
I'm sorry to have to say this, but if I had taken the images you posted here, most of them would have been consigned to the cutting room floor. One of the main reasons why I don't post so many images on this forum is that most of mine lie on the cutting room floor too.

So - better or worse? A starting point or as good as it gets and best left alone? Where would you take it?
I greatly appreciate your help with this, folks, and I'm determined to do the best I can with this image. You'll probably find this amusing, but I did put a 16x12 print of the first image in the thread in my camera club comp. It should be interesting to hear what the judge has to say about this (29 May).
