I use Hugin for flat (mosaic) stitching to increase resolution on large-format film negatives using a digital camera. I made a video tutorial for this using a recent version of Hugin, as some of the tutorials on the web are for out-of-date versions and no longer work well.
This type of stitching is for stitching photos where the camera position shifts laterally, keeping the sensor in the same plane as the subject, or in my case shifting the film laterally while the camera is stationary. This differs from the more normal panorama where the camera (or rather the nodal point of the lens) rotates.
My tutorial is a screen capture video that’s about 15 mb. Can I upload it here?
missing exif data shouldn’t matter, since hugin asks for the focal length when you load the images onto hugin. just set the field of view to something reasonable, i.e. less than 45 degrees or so - for flat stitching it’s not important.
I think @Morgan_Hardwood is right. @yteaot can we expand this into a post on the main site as a tutorial? Do you want to flesh it out just a little bit with me?
Just ignore the horrific posterization in the web-viewer image Flickr generated, all of the download sizes look better In this one I used 15 exposures to get an effective sensor size of about 3.2x3.5 inches, although I cropped in quite a bit for the final edit (cropped from ~200MP to ~100, which still makes GIMP choke). I could have covered the whole space with just nine, but using the digital back on a view camera seems to generate some pretty pronounced centerfold artifacts in the shadows, and with some duplicate pixels in the in-between spaces enblend seems to do a pretty good job of smoothing them out. I just have to accept that it’s gonna take some time to process one of these monsters
I stumble upon a new software (for me) at work for stitching (and specifically, flat stitching).
It’s called ImageJ. I play little around with it (the Fiji flavour, which contain stitching plugin). I found the Pairwise Stitching very effective, but as the name imply you can only do it by pair so if the collection contain a lot of image it tend to be click intensive.
There is another plugin Grid/Collection stitching, which seem very close to what @bieber was looking for. You can feed the plugin with image in a dedicated folder and choose from the various way of ordering them to help the plugin do the stitching. I have to admit that I didn’t succeed to make it work with the provided files, but I didn’t spent much time on it either.
Shooting a long graffiti does not work with one picture. In the next video I will show you how to photograph a very long graffiti.
Camera for manual control. Take each image while the camera is parallel to the graffiti and at the same distance and height. Do not change the zoom.
