These images were originally captured by Aman Zafar on 35mm film using a tripod mounted, high quality camera.

The images show flashes occuring inside the Twin Towers on numerous floors during the time the towers were burning. One flash in particular (shown below) appears to have blown out windows on that floor and smoke is later seen emanating from the previously undamaged portion of the building.

These bright, white flashes would seem to provide corroborating evidence that explosions were occurring inside the Twin Towers prior to their "collapse", as shown in this video ...

The flashes all have similar distinguishing characteristics. They all have about the same diameter, being approximatly equal to the width of the windows, they are all roughly circular in shape, they're all the same white color, and they all have similar luminance and granularity.

The granularity of the flashes is of particular significance, since it is consistent with the granularity of the rest of the image and clearly distinguishes the flashes from dust particles or other contaminents or blemishes that might appear as white dots on the image.

The following compilation of images shows the difference between a flash and a contaminant (speck of dust) on the surface of the scanned photo. Note the difference in granularity - the contaminant has a sharp edge whereas the flash is less sharp and consistent in sharpness with the rest of the image.

The next two images, showing a portion of the South Tower above the 78th floor, taken with the same camera from the same location, provide a comparison that demonstrates the camera's ability to capture light from individual windows of the WTC towers under varying light conditions.
