Should I use this or not? HDR of Aqueduct

[ericmark]

Goodness that must have taken some time but result is great. I also considered adding something not as good as yours. same basic idea. However I looked at the time and although it can be done I think to ensure I don't run out of time in the exam I'll select another set of images. Why make it hard for myself.
However I have copied out your method and I am going to play with it may come in handy some day.
It is very different to my trade as an electrician. Either it works safely or it doesn't there are is no near enough. I was going to say Black and White but that's not right it's all Black, Gray, Brown and Blue with at little Green and Yellow for good luck!

I like your effort as well.

Oh hey ... was my explanation for the radius and threshold sliders of any help?

[ericmark]

Yes it was. Sort of working things out now. Seems course is run both as evening class and day class but in the day most students are 16 year old and no real interest in learning. As a result the lecturer is not getting into things as he should. So it's left to us who do want to learn to look it up on internet.

He has people in class who openly say why do I need to learn about aperture and speed what's wrong with auto. But I only paid £5 for class so can't really complain too much. And slowly it's sinking in. I was taught more about Photoshop when I did IT course and Photoshop was just taught for 4 weeks than on this course which should go on all year. But last time it was version 7 and there are so many extras now.

I think only way is to practice. I have now given up taking Jpeg photos they just fill up my memory card and unless I need to take loads very close together Jpeg will stay off.

But I look at the RAW panel on CS4 and there are so many options and it seems many tools do basic the same thing. If I look at histogram at top and make sure it spans whole length then once opened seems no need for me to set levels.

We were told to set Un-sharp mask at 175% and radius 1 but not a clue why we should set it to that? In RAW there are also settings for sharpening I see it move histogram but not a clue what I am doing. Maybe we learn that next year suppose they have to have something left to teach next year!

Considering course does not finish until June seems odd to have exam in Easter. I am also doing maths and what a difference. The maths lecturer does not miss a minute of time. And it's go go go. But this art course seems to be so laid back progress is nearly zero. You have taught me more in last week than course has taught me in last 3 months.

It does not help that college uses MAC's great as they are all of us have been taught with PC compatibles to date and the lecturer spends loads of time showing silly things like how to take a screen shot.

Anyway you have all been a really great help. And I am sure I will pass. Mind you can't say same for maths. We are taught in maths about the magic proportions and how since the ancient Greek's we have used this number to proportion structures and paintings. We are shown the last supper all divided and shown how it all fitted. Talk to Art lecturer and he had never heard of it! Seems odd to learn about Art in maths class but so many famous artists of past were also mathematicians.

Sorry off subject I know once I start no stopping me. Did try your method no where near as good as yours seems I need a lot more practice.

Not sure what they told you but the histogram isn't that simple at all. It shows a graph that represents the different shades (or colours) of pixels in your photo. Those will vary tremendously depending on the photo. A photo of almost just snow is going to be heavily lop sided towards the right hand side. A photo that is mainly dark will be lop sided the other way, to the left.
The important thing is to let the histogram suggest to you if you have any of the darker sections of your photo simply too dark or any of the brighter sections, too bright. Basically, unless you intended to 'clip' one of those areas, the histogram graph, no matter what shape it might be according to the photos contents, should dive into both bottom corners and not have either the dark or light side up the sides of the graph.
All of this tells you very little about whether you need to set the levels or not. A good, calibrated monitor and your eyes are best for that.

We were told to set Un-sharp mask at 175% and radius 1 but not a clue why we should set it to that? In RAW there are also settings for sharpening I see it move histogram but not a clue what I am doing. Maybe we learn that next year suppose they have to have something left to teach next year!

To set unsharp mask to 175% and radius to 1 can only apply to a specific photo at a specific resolution.
As I said earlier. the radius affects how many pixels are affected when the sharpening is applied around the pixels the filter has selected to sharpen. The more resolution, the more radius you usually need. Sounds like you had a sample photo and the lecturer has failed to mention that those settings work well with that photo because of it's content, size, and original sharpness/softness but the settings need to be varied for each photo. At a given resolution you can sometimes find settings that will do an ok job over many photos, especially if the effect is slight.

Considering course does not finish until June seems odd to have exam in Easter. I am also doing maths and what a difference. The maths lecturer does not miss a minute of time. And it's go go go. But this art course seems to be so laid back progress is nearly zero. You have taught me more in last week than course has taught me in last 3 months.

You'll find isn't unusual if you hang around here long enough. None of us know everything, but many of us do know what works for us and what tools and settings to use to get those results. Feedback is vital, and if you are the sort of person that can handle both negative and positive feedback and at least try out things you are told here, you'll learn quickly. Come here with pre-conceived ideas that you know it all and just want pats on the back and your learning will be slow.
We all learn here. I know I sure do.

Not many of us (especially me) can learn things in one go. Practice (and repetition) makes per ... reasonable to great

Thanks yet again. And yes I will accept criticism and listen to what is said. Unlike some great artists I will not cut off my ear. I'm Welsh not Dutch!

The picture is interesting it has some Tolkienish to it, like a painting of another world, tho the upper corner is blown out, and I suggest you use HDR technique to repair it
