Do you saw Blow-Up? Do you know about photography chemical process and technique?

Hi!


I need to do a description, for the school, of what David Hemmings does for print his photographs (well, the common process..). I'm starting to learn about photography and never print photos in laboratory so I don’t know exactly how it works, if you can help me…





Here are the stills from the movie, of what I want to ask:

Do you know why he puts the negatives on that “box”? (what’t the name of the box?) (No.2)


The clock that he put it’s to control the timing of what? (he starts the clock before he puts in that box) (No.1)


Before he puts the negatives in that “box”, what it’s necessary to do first?





This movie is from 1966. Something is done differently nowadays in photographic chemical process?








About the cameras that he uses, do you know which are the cameras and film formats? (just a guess).


Why he uses this camera to photograph far away from the model? (No.3)


And why he uses this camera to photograph close to the model? (no. 4)


And why he uses that to photograph in the park? (it’s seems similar to the previous one, but here he is shooting in distance, so what’s the difference between this two cameras?) (No.5)


(If you know the names of this cameras you can say too)








if you want you can say more things about it, that you find relevant.


And if you don’t know everything just ask what you know, I appreciate.





Tks.|||1. The 'box' in number 2 is a drying cabinet which is big enough to hold many films, he is removing the film which he has just processed, he is holding it by a metal clip to which he fastened the film after it having washed it.





2. Almost certainly his film is in the tank in front of him in picture 1, this washes all the chemicals out of the film, he sets the wash time which on average is 30 minutes.





3. The film has been 'developed' then 'fixed' and lastly it is washed before drying.





4. The chemical process in 1966 is exactly the same as it is today, only the type and style of the equipment has changed.





5. The camera in 3, is almost certainly a Hasselblad SLR (Single lens reflex), it uses 120 film and the format is 2 and 1/4 inches square.





6. You can't tell from 3 how far in front of him the model is, in front of him is another photographer taking his picture. It's quite normal in portrait photography to use a long focus lens, this gives less distortion than a normal angle lens.





7. The camera he is using in 4 is a 35mm SLR (single lens reflex) camera, it is sometimes handier for close-ups where it gives greater depth of field.





8. The camera in 5 is exactly the same one as in 4, it's a matter of his own choice which camera he uses, in general the Hasselblad would be used in a studio while the 35mm is lighter and quicker to use, but it's his own personal choice which he feels more comfortable with. As the negatives are larger in the Hasselblad they would be more suitable for bigger enlargements.





It's very difficult to say what the make of the 35mm camera is, both cameras are completely manual in operation, they contain no batteries and the shutter speed and aperture would need to be estimated with an exposure meter and the focussing would also be manually operated.|||Thanks, ines, you are welcome to contact me any time, photography has been my passion for over 50 years.
