    Hi all,

    I have a few questions that i need answered as part of this photo course that i want to do. I'm hoping to improve way beyond my amateur level.
    Searched google with no luck so maybe you guys can help.


    - When using both color negative and transparency films, do we work out the correct exposure the same way, if not why?

    - Any disadvantage of using a telefoto lens?

    - What happens to film if subjected to a magnetic field?

    - What is a quick way to color correct an image containing a white or grey area?

    - What is the maximum value of a pixel?

    thanx in advance, appreciate your help!

    It should say in your books if you're doing a class. Also, you should be paying attention in class.

    I'll give you my answers to some very silly questions
    1 yes except for a possible difference in iso

    2 The difficulties of using a telephoto lens is that it will react quicker to camera shake and therefore a faster shutter speed must be used,also the weight can make it difficult for a nine year old, However if your subject is a long way away the advantages out weigh the disadvantages :)
    3 nothing, but x rays can damage film
    4 correct the color so the white is white , but as the question states it is white I've no idea :)
    5 I've no idea but it seems to be about a cent a pixel :)

    In my day the questions asked were about things like reciprocity failure or reticulation
