Description

This is the view from the old Severn View service station. You can see the old bridge in the foreground and the new bridge in the distance on the left. Before either bridge was build you had to cross using a ferry which no longer runs. You can see all three crossings in www.gigapan.org/gigapans/54012/ . There is also a 360 from this location here www.gigapan.org/gigapans/54195/
Didn't really nail the focus on this one. What I find really annoying is that *no part* of this image seems to be in focus. This seems an unlikely possibility to me but if you can work out at what distance objects are in focus then do tell me by taking a snapshot.

Also *most annoyingly* the camera filled the card before getting to the end of the shot and I didn't notice so you can't see the sun-lit power station (see www.gigapan.org/gigapans/54195/snapshots/151901/).
What's more, it was a lovely blue-sky day (see the later shot www.gigapan.org/gigapans/54012/ ) except for the hour from when until I started taking the gigapan until the camera filled the card.

AND HDRSoft still haven't released any software that can cope with normal-sized images like this one so I will have to put up with the white sky for now.

Grumble, grumble, grumble :-)

    Details added. Glad to receive any thoughts you may have.

    Pity we can't see the full details of your GP in "view", as those details might indicate your problem, my suspicion is that it's all to do with Light. Photography is all about light and it's value, the human eye can process more, so the scene looks brighter to us. I think that the EV value was low hence less exposure etc. When using such a lens (I have one) a lot of photographic principles apply, and when one tries to amalgate long lens Epic head light, it doesn't always work out as our eyes saw it. As I said in recent emails I've changed quite a few timings on my Epic Pro towards achieving this aim.

    It may not be quite as slow as you think. I have 8GB of memory plus a 300GB Velociraptor as Photoshop's scratch disk. I think it took about 20 minutes to sharpen the entire pano. The result is here tinyurl.com/3ys2ydz Will open in
a new tab or window but it is not as good as what you showed me in your email. I shall investigate more later.

    To sharpen the entire pano, Photoshop has to keep the unsharpened version in memory (as an undo buffer) PLUS a subset that it works on, PLUS the finished version. That's a lot of memory. It'll have to write the working part out to the disk, slowing things down tremendously. In comparison, batch-sharpening each image takes only a few seconds each, after which you stitch again.

    What am I missing? Surely there are fewer pixels to be sharpened after the image has been stitched? If my maths is correct there only four-ninths as many pixels in the complete gigapan (assuming a one-third overlap).

    Oh, before stitching, definitely! If you're using Adobe Camera Raw (which works on TIFs and JPGs to) you can batch-sharpen the captures, saving a ton of time.

    Thanks for those ideas Tom. They are all worth trying. I never sharpen any of my images simply because I never think to do it - strange as that may seem. I guess it's because I had no interest in photography before I started gigapanning so I was largely ignorant of what tools like PS can do. These days I know something about levels but that's about it. Do you sharpen before or after stitching?

    Some thoughts on sharpness: 1. Test for sharpest f/stop. Lock the camera down on a sturdy tripod (no gigapan) and try various f./stops. I found my Nikkor 70-210 was noticeably sharpest at f/11. 2. You are looking through a long column of air. On a sunny day the atmosphere will be boiling with turbulence. You may need a faster shutter speed than you think in order to stop that movement. 3. How steady is the GigaPan Pro? Do simple 9-image panos of a nearby subject on a calm-ish day, varying the shutter speed. What shutter speed and/or button-push time are needed for sharpest results? 4. Are you sharpening enough in your processing software? Really crank up the sharpening and see what you come up with. best regards, Tom
