Description

An unusual view of the Circus in Bath. This is really a work in progress. I hope to return and do the job properly soon. What you see here is made from two sets of images taken from different viewpoints in an attempt to get a shot of the circus without all the scaffolding. Hence the 'bad stitches' and parallax problems.

    Far be it from me to tell you how to take your gigapans. I merely point out that the correction of CA can be done quickly and simply if you have the right software (which you do).

    Thanks for sharing that with me/us. I have PS, ACR and PM so I can certainly try what you suggest when I next notice a problem. To be honest though, until recently I have been producing gigapans so fast that I don't have the time to look at individual frames. I simply chuck everything into AP, make sure the picture looks straight and level, press the Smartblend button and I am done. Of course that's an exaggeration, but it gives you a reasonably accurate sense of my workflow. I guess I am more interested in developing contacts (like Coexist and The People's Republic of Stokes Croft) so that I can get the technology to as many people as possible than in crafting the perfect gigapan. (I am not saying this is any better or any worse, just different.) However, now that I have a 36" carriage printer I am producing prints and that's opened a whole new can of technical worms, so maybe I will slow down and make the time to think more about what I am doing. To be honest again, I rather doubt this will happen :-) I still don't really know how to use a camera. From time to time I ask my photographer friend about some technical issues like how hyperfocal distance varies with lens length and he almost always says "You know, it would be a lot easier for you to learn the basics of photography if you took your camera off the gigapan imager and tripod" but I never do ...

    Photoshop certainly; I don't know about Lightroom. You use Adobe Camera Raw, which is part of Photoshop, and can adjust red-blue and yellow-green aberrations in real time. Zoom in to 100% and watch a high-contrast part of the photo (window frame, tree branch) as you slide the sliders. The photo becomes noticeably sharper as the channels align. Photomatix has a checkbox to fix chromatic aberration, which is not totally successful. I save as TIF from Photomatix, then open them all in ACR and batch-convert them as JPGs, correcting CA, sharpening, and adding Clarity (i.e. midtone contrast).

    I don't know Tom. What do you need? Lightroom? Photoshop?

    HDR really accentuates chromatic aberrations. Do you have the means to correct them before stitching?

    This is not just an unusual view ... it is a unique view of the Circus. Not many people have the courage to stand on a scaffold to take a 0.12 gigapixel view as what you have taken. Really, in all the research I have acomplished concerning Bath, I have never seen this view anywhere in all of the photo records.
