  • I like to challenge myself and love shooting black and white film at night, I think the organic look film gives is still unsurpassed even today, on a very dark October night I load the 4x5 film camera with 1 sheet of Ilford HP5, watch the video and see how I got on, enjoy.

    Martin you never cease to amaze me, the determination along with application of knowledge has given you a very successful print, that I think an awful lot of photographers would have struggled with, even on digital, a credit to your photographic and dark room skills, any longer and I think the restaurant would have started blowing out and would have ruined the scene, it’s a pity it wasn’t a clearer night for the sky. But a real lesson old plate or any film photography.
    I will be looking at your other videos and seeing what I can glean from your developing skills.

    Lovely photograph, Martin! Thank you for bringing us along.
    In my small town, trying a shot like this would have at least a couple of police officers asking me what I thought I was doing. :)
    And, in my experience, they will stand directly in front of the lens while I explain.
    With the added "fun" of being told some variation of "but it's too dark, you can't really be taking photos now." Thankfully, one of the advantages of being as old as I am, they don't see me as threatening just a bit of a fool. Not entirely pleased by that but it does make the encounters slightly less annoying.
    Always happy to watch another video from you, thanks again!

    Very nice. I've done a lot of analog night-time photography, most of it panoramic (6 x 12 and 6 x 17 cm), until a few ears ago. Almost all of it on C-41 colour neg stock. I've had exposure times up to 2 hours, often in clear winter nights at sub-zero temperatures. Just opened the shutter and spent the next hour or two in the car, listening to the radio. 🙂

    Dear Martin, Did you know that when you unscrew the top two screws of the partial image viewfinder, you can insert two penlight batteries. When you press the red button on the side of the viewfinder, the light projects two points of light against the object. When you use the focus button to let these points of light fall on top of each other, you are focused. I hope you find this useful; Although it is rather suitable for not being used over too great a distance... For most users this is a hidden thingiedingie.

    Wonderful work Martin! Showing us how it is done! Agreed, film has a more natural tonal quality. Digital (as it is commonly executed) is too linear and starkly rendered. Analog materials provide a more nuanced portrayal of light. Unfortunately, this aesthetic is admired by the few, in deference to the "killer shot". Thanks for taking the time to reveal your images and your process.

    Last summer I exposed a frame on RPX25 at f/2.8 for about an hour and a quarter up at the Bivouac Refuge Igloo des Pantalons Blancs (about 3300m) (it was on 35mm however). I left the cabin and the bed therein twice that night to make the exposure. The negative was somewhat underexposed, but the image came out wonderfully (a silhouette of the peaks of La Sale and Le Plereur (I think) against a backdrop of star trails, and some annoying plane trails that were a pain to retouch).
    Now I really want to take my 9x12 up somewhere like that again, with some of my (self-made) dry plates. :)

A bright led flashlight works well too, to light up something like the branches over the water. I have focused quite a few times at night on the glass without problem.

    Incredible image Mr. Henson! Is the image in the video a scan of the negative or a print? I'm simply amazed at the amount of details and the lack of noise! Does HP5 have an ASA 400 rating? It would sound about right for a night shot at f/16 and an hour long exposure. Just out of curiosity, do you ever shoot any 8X10's in large format? I've watched some of your videos and don't recall ever seeing any. Keep up the great work! Cheers

      I5 mins would have produced a very thin underexposed negative, the app is called Reciprocity failure app

      So base exposure was [8mins} 480 sec to the power of 1.31 = 3254.063 seconds divided by 60 = just over 54 mins, I rounded the exposure to 1 hour, I think you are using the base of 8 when it should be 480
