Hi Greg!
Oh yes, now I see! I had the specs for the powershot S1 but not S1IS. And I can understand very well the itchy feet! So, do get out and take some shots! Still here? Go, go for it! :-)
Cheers,
Nick

Hi Nick. The powewrshot S1IS smallest aperture is F8. Maybe you looked at one of the other powershot series as there seems to be alot of them. I pretty much leave it on apperture priority set at F8 all the time for my landscape shots. Would love a camera with F22 or more. All this talk is giving me itchy feet to get out and take more as I haven't been out for a while.
All the best
Greg

Hi Greg, everything's fine, thanks. Hope you're doing fine too.
There can be loss of sharpness when resizing but it rather happens when enlarging the jpegs (or any other format). Decreasing size is less prone to such problems though it also happens now and then. It also depends on the scaling algorithm, and of course on the image itself.
I took a look at the tech specs of your camera, which does look very nice. They say that it is F2.8-3.1 and 5.8-58mm - so you must mean focal length and not aperture?
As about aperture itself, the numbers 2.8-3.1 are likely to be the widest aperture but I think that such a camera does also use narrower apertures - for example in "landscape mode" or any similar program. And since you also have manual settings you can also set a narrower aperture than 2.8 or 3.1. or isn't that possible?
Anyway, the tech specs also say that it can focus from 10cm up to infinity and so there has to be some possibility to get the whole range from 10cm to infinity sharp at the same photo - or so I guess.
Keep it up and best wishes,
Nick

Hey Nick hows it going. The reason for reducing size is to get them to fit on this site. I have been doing a wee bit of reading about it on the net and appearantly there is loss of sharpness in resizing jpegs. They give advice and I'm going to have to explore these more. I agree with the Narrow aperture and longer shutter speed to give depth and colour but unfortuantly my camera only goes to F8. I really need to upgrade to a better camera or get the film slr out of the closet.

Surely, reducing the size of the image is likely to increase sharpness, Greg. But this one is perhaps a very nice example for trying narrow apertures, long exposures - and thus tripod, and also hyperfocus to win sharpness in the near field. It is there where the soft focus starts taking over. Mastering these few things you will almost never need to reduce the size of your images, or to sharpen them afterwards.
Best wishes,
Nick

Thanks Nick for you comments - always much appreciated. You talk about lack of sharpness which is something that has been said about other photos I have taken also. I couldn't work it out but now think it may be in reducing the size of jpegs. Someone recently told me that reducing the size reduces the sharpness and quality. When I look back at the full size original I can see the differences. May have to sharpen my skills and look at a way of sharpening the reduced jpeg.
Thanks Greg

Nice balance betwen the electricity poles and tzhe mountain, Greg! some more sharpness would have helped and also perhaps a step to the right for enhancing the perpective through the series of poles . (Though I am not sure about the latter.) The overall impression of low light makes the distance feel even more far away, and thus the mountain even higher!
Best wishes,
Nick
