Taking photo of object bigger than the field of view of the Foldscope

Many times we observe objects which are so big that we can’t take its photo as we have panning stage to move and take multiple photos.

In this post I’m describing a method with which you can take multiple photos of a big object and then stitch them together to create complete picture.

I took above photos of wing of a moth. For each photo I moved the focus slightly to the right.

I use a software called Mapstitch for combining the multiple images. The app is available here: https://play.google.com/store/apps/details?id=com.bcdvision.mapstitch

All you have to do is, open the app and it it open the multiple images you have taken. It stitches the image by using the common pattern in images and creates one big image. It is like the panoramic picture we take with our phone. The only precaution you have to take is that, each picture should have some common part and some new part. Two successive pictures can not be completely different, then software would not know how to stitch.

Resultant image looks like this.

    Brilliant. Love the result 1 clearly more and more apps that are very relevant for microscopy are becoming available on cellphones.

    Here are older attempts at stitching and focus stacking.. so we have list of apps in one place. Maybe someone should make a dedicated post on top ten apps for foldscope users 🙂

    Thanks for the links Manu. I have been thinking of improving the photo quality by focus stacking. I’ll follow your post and try it.
