After research and viewing these videos I believe You can see evidence of thin film interference on digital photographs too. One of the video is digital and it also shows color produced through TFI. Old style film cameras can also show color produced by TFI. So my pictures were not misleading. It showed the color in a soap bubble produced by TFI. Eeven bubble maker used for the purpose but soap water used for that so you use old tradintion blower and blow with mouth or use machine what’s the difference?and why it should not consider TFI? PS: Waitng for yur pics; Qiyamat se pehly post hu jain gi??
