  1. Can anyone recommend a workshop (Europe/Americas) early next Spring?

    Subject matter not wild-life preferably, landscape fine,

    people & documentary ideally.

     

    Of course I shall be shooting medium format, or else my message will

    be rapidly deleted from the forum!!! Information will be much

    appreciated.

  2. I may have missed reviews of this camera. I would be interested in

    comments about its strength and weaknesses. Black & White reportage

    would be my main usage. What is it like on the hoof? Is it user

    friendly, reliable and robust? Does it chew batteries, have a

    slow/fussy autofocus, fiddly controls? Is the zoom useful or are the

    fixed focal lengths a better bet/lens. Is the Mimaya 7 a superior

    alternative?

  3. I have now obtained the information about the development of Delta

    3200 with AcuLux 2 from Paterson directly.

     

    <p>

     

    Dilution 1+5 at 20 Celsius Gbar 0.57:

    800 ASA=9min,

    1600ASA=11min,

    3200ASA=13min,

    6400ASA=15min and

    12,500ASA=18min.

    They comment that pushing the film to the higher speeds will

    compromise contrast quality

     

    <p>

     

    An alternative is to use dilution 1+9 at 24Celsius and the times are

    identical

  4. I hope I am not missing the point of your question. The D40 functions

    satisfactorily on the flash-shoe section of a PME-90 Prism. This

    serves merely as a mechanical mount and does not contribute to the

    electronic activation/regulation of the flash. These functions of

    course are provided by the leads passing to lens and camera body

    respectively.

  5. Can anyone suggest a suitable book for me on B&W dark-room

    techniques?

    I consider myself a borderline "intermediate"/"red-run" printer.

    I do not want to read another book about types of enlarger.

    Although reasonably mathematically minded, I would rather not wade

    through a detailed account of "Dmax".

    As a surgeon, information that does not alter my practice is fairly

    irrelevant. Tips and hints are, however, invaluable. The same

    applies to photography.

    I am familiar but inexpert with the basic toning techniques.

    I use split-contrast printing but without finesse.

    How does one adjust the basic "correct" exposure at contrast-2, to

    take account of using contrast 3.5 and 0.5?

    Why 3.5 and 0.5, why not 4 and 1, etc....

    Is there a mathematical relationship or is it trial and error?

    How best to plan test-strips?

    And so on. Many may have passed through this stratum/level and I

    would be very grateful for suggestions about suitable reading.

    Or, is it just practice?

  6. All photography clubs I have contacted in the South East (UK) are not able or willing to admit MF slides for week to week presentation. Much sucking of teeth. Suggestions have included chopping up my slides to fit 35mm holders, reshooting or copying. Very discouraging. Is there a group in SE (Kent, Sussex, Surrey) who welcome or specialise in this format?
