Hi,

I have attached a link to the first attempt to convert a super 8 to digital frame by frame.

I am still learning, but need a bit of advice please.

The picture seems dark. It scanned this way and when I play it through my projector it is also on the dark side.

Silly question time, was it just a cloudy day or is there any way to brighten the film up?

Hello Andrew. The extract you put on YouTube is very short (a few seconds) so it is difficult to make one's opinion. Frow what I saw it doesn't look too dark. It seems logical that if the picture looks dark through the projector, it will also look dark copied. To answer your question, it is possible to brighten the picture but don't expect too much. The projector you use can make the difference some projectors have a 100 watts lamp, others 150 watts. The lens aperture has an effect on the brightness as well : a 1.0 aperture will make a brighter picture than a 1.3 aperture. And an often neglicted thing can also help : the surface on which you project. A white surface will of course be better than a grey one. I assume you are aware that you already know that the smaller the picture is the brighter. Hope this can help.

Thanks Dominique,

I guessed it was a cloudy day when it was filmed.I wasnt sure if there was a cleaning liquid I should use that would brighten up the film, or I should be happy with what I have.

Did the one second clip by scanning each frame and building an avi file with the images. Used 18fps, I assume thats about the right speed.

I am quite new to this,been collecting various formats (main interest id 9.5) for a wile, but to be honest not tried digitising them before.

Thanks

Andy

If you are using a videocamera, simply disable the auto iris control and increase the iris aperture. Of course highlights (e.g. the sky in this sample) will be washed out but you'll get more detail in the darker areas of the image. 100 W bulb and a 1.3 aperture lens (or less!) are more than enough in fact you don't want too much light output when you do this operation since modern CCDs are so sensitive. Also why is the picture reversed? The sprocket holes should be on the left side when projected...

I thought I scanned them the wrong way round. I originally did it with holes on the left, then saw a couple of examples with holes on the right, so got totally confused!

Will do it again the correct way round, thanks
