36 shot portrait panorama

Required: normal or tele lens with very narrow depth of field, tripod, patient or stationary subject, panorama stitching software.

 

Results: large format-like narrow depth of field combined with very wide angle of view.

 

This shots was with the M8, 50 Lux Asph at f/1.4 at about 1.5m. The effective angle of view is around 21-24mm. 36 Shots, and Autopano Pro. Lots of patience with the software, which is excellent, but which I just bought today, so I am still on a steep learning curve with little documentation.

 

The next time I will try a 75 Lux, a little closer :)

Here is a WATE shot at 21mm for comparison, wide open. I got lucky that as I was doing the panorama, the sun jumped behind a cloud.

Carsten,

 

Can you say a little more about the shooting technique? Did you shoot this in a grid pattern? How much overlap?

 

Thanks

I shot willy nilly :) To minimise subject movement, I quickly grabbed her in two shots, and then shots lots all over the place, more or less in a top-to-bottom, left-to-right sequence. Autopano takes all this over, and I didn't have to do any manual interference to get this panorama, other than setting the centre point on her face. I will do another with some corrected verticals, but these funky curves may end up looking more interesting. I wouldn't have the foggiest notion how to produce them on demand :)

 

I was under some time pressure due to pedestrians walking past, and the sun being behind a rather small cloud. In fact, due to missing coverage I had to crop perhaps 30-40% of the image!

 

Having a little more experience with Autopano at this point, I would recommend a 20% overlap where there is detail, and as much as 50-60% overlap where there is little detail, such as in the out-of-focus regions in a macro shot. I am still having trouble with my macro pano. I will post a preliminary result today, but I may have to reshoot to get it all. Some regions just won't stitch.

Here is the problematic macro panorama, in the control point editor. Well, not so much macro as closeup, I suppose. It was hours of work to get it this clean, and there are still problems and lots of missing connections.

Great image and technique Carsten !

It seems shot with a Linhof Digital and 90/2 lens wide open :D

 

As I'm interested in pano images (Mac platform), how do you like Autopano compared to other similar software ?

 

Thanks :)

Autopano is the only game in town. I have Canon's stitcher, and it works great for left-to-right easy panoramas, but nothing else. I used to use Panavue's Imageassembler on Windows, before switching to the Mac, but it was not this good, and required more fiddling. They also stopped developing it within days of my buying, which left me with a bad taste in my mouth ("yup, Carsten has paid. Okay everyone, go home, we are done here").

 

I have been trying forever to get a copy of Realviz Stitcher to evaluate, but I can't get one, and I hear mainly bad things about it, apart from the price which is five times as high. The Autopano developers are friendly, and the program works perfectly and automated for most situations. I just happen to be really pushing it, what with my 3 blurry shots in a row, for several columns :)

 

PT tools are meant to be good, but very manual and technical.

Here is the best I can do for now this image. This really highlights how hard it is to estimate if you have enough coverage. I thought I had lots extra. Due to slight twists in the stitching which it is nearly impossible to fix, as well as the circular motion of the camera on the tripod, the corners ended up with insufficient coverage. Back to the drawing boards :)

Well, I was ill all weekend, so apart from sleeping, blowing my nose and drinking tea, I did a lot of work on these panoramas. Today I redid the problematic rose, and here is the final result. I still want to darken that spot in the top-left corner. Can anyone suggest the best way of doing that in Photoshop Elements 3 on the Mac?

 

100 images went into this one. The exact procedure is written in my photo blog below. I cropped it square as a nod to my old Hasselblad 500C, which I kinda miss using. I love this medium/large format look, and I am so pleased that it is possible to get this with the M8, even with restrictions.

AutoStitch

 

This is the code that autopano is based on (see licensing). There is a free version there that can do some amazing work, but limited to jpg's. A starting tip for using autostitch... Edit/Options set "Output Size to 100%" & "Other Options Jpg Quality to 100%" and it won't be shrinking/compressing your output. You can do that later in conventional software.

 

I've tried a number of free stitchers over the years & this free one blows away everything else (including Canon's which is not bad for simple stuff, and Photoshop's).

 

If I had a need for serious pano tools I'd be looking at this commercial version Autopano.
