The trick is this (for good camera with high resolution only): you can keep a distance from the T, far enough for the camera to focus right onto the T and then take a pic at maximum resolution. I mean you don't need the T to fill the entire pic, just make sure it is well-focused. Then you use photoshop or any photo editor to crop it just around the T then zoom in to make sure you can see the EF area clearly then upload it. Make sure to take it under good lighting as well.
I didn't use that trick on a T but on my palm with a white strand of hair and I was able to see it very clearly. Maybe just my camera.
