Hi There,
i am new here and new to panorama photography.
I have created my first panos now using autopano and was wondering about the image size. For further understanding i will post details of my case.
i imported 17 pics 8,1 megapixel per picture, with a size of about 3 MB per pic. ( i have noted that the source pics are oddly small for 8MP )
What autopano spit out was a pano with 17 images, STA_6089 - STQ_6105 - 17764x2667 - SCUL-Smartblend and a size of 8,6 MB.
Now i am wondering how this can be. Since i want to have a big poster printed out with highest quality and detail possible i was expecting a jpeg file size much larger than 20 MB.
Did i miss something, or some setting on how to get the most possible out of the images?
Help is appreciated

What camera and lens did you use?
Was this is partial pano ie. with less than 360x180 degrees field of view (FOV)?
Was it shot hand-held or using a pano head?
Don't forget you have to consider that the images overlap; usually by about 30%.
What is the resolution of the stitched panos image?

Hi meiavets,
this was a 360° pano, one line of pictures. It was shot hand held.
as written above, the final resolution is 17764x2667.
pictures have been shot with a canon s70
even expecting that a 30% overlap which is truely easy possible i would come to a calculation something like: 17 Images at 3mb = 51 mb cutting of 30 % will in my theory result in a 35 MB panorama. This is way out of bounds from the 8,6 MB i got out.
greetings

How much did you crop the stitched pano image?
Can you also post a screenshot of the Editor view with image locations displayed (click on the Layer Mode button) - like this:

Which jpg-quality did you set for rendering? 
8,6MB jpg best quality possibly could mean around 50 MB filesize or more . .
depends on your settings and the kind of pictures (details, colours).

I used JPG Quality 11
here is a screen shot:

Well I think your answer is apparent from the screenshot.
Fisrt of all about a quarter of the images appear to be redundant - from the point of view of covering the scene - with very large overlaps between some, and then you'll also lose pixels when you crop.
Do you recall whether you had the camera zoom set at max. wide or max. tele?
Did you hold the camera in landscape or portrait orientation?
With this quite limited vertical FOV did you try a cylindrical projection?

I did not have the picture cropped yet.
I had the camera at max wide / tele, holding it on landscape mode.
i did not try a cylindrical projection.

Your stitched pano has approx 47.5 Mpixels. From the screenshot it looks like an image that would compress well.
I think you shot in Super Fine JPEG mode if each image from the camera was approx. 3MB?
I reckon that if you had used a click-stop pano head then 10 or 11 images around would be sufficient to give at least 30% overlap with the Canon S70 camera at max. wide (28mm equiv.) and in landscape orientation.
Try a cylindical projection it may better suit this pano.
