ISO 400 Film with ISO 200 camera
-
Hi
I have a Film roll of ISO 400, if i set my camera at ISO 200 does it work if I put down -1 (one stop down)
or ISO 400 Film with ISO 800 Camera mean +2 (two stop up)? just an idea if we can allow to do that?If you reduce iso 400 to 200 you over exposing by one stop. If you increase say 400 to 800 you are under exposing by one stop. A lot of photographers will rate their films lower than that recommended by the manufacturet something like HP5 250asa Acros 100 50asa.
yes and you may need to compensate for that shift when it comes to developing.
If you over expose by one stop you should under develop by about 20% per stop for b+w.johnnycorcoran wrote:

If you use a 400 speed film but set the camera to 200, you are over exposing by one stop, but you then say you are closing one stop down (aperture I presume?) which makes up for change of film speed, so no need for reduced development.
Why not just set the camera to ISO400 and shot away normally?
Hi I thought that once its getting dark (indoor) I can bring down to iso200 to get my light in…so I can also put one stop under..anyway was talking to john gunn as they said that I can BUT must use the whole film without changing back and forward…

What do you mean by “so I can also put one stop under”?
Ok so you are trying to pull the film, i.e. overexpose and under develop. This may help you produce more shadow detail when shooting low light situations as you mentioned, but if you are only starting with film you may be complicating things for yourself. I’d recommend shooting a few rolls normally until you get used to it and then try pulling or pushing the film. Will you develop them yourself?
Cheers… Yep I’m learning but I do understand the camera as I always use the exposing over and under on my digital camera,(I’m sure it’s not the same) but sure I can keep practice…
I will use john gunn to do me a negative so I can use my scanner at home. Cheaper that way :)
The more I learn the better I can getBuying the few bits required to develop at home (you don’t need a darkroom) will save you money if you start to shoot film regularly.
Hope you enjoy your films, you got a nice selection of them to try :)
Thanks..is this the one about the bag and negative and do it by hands inside the bag? If yes, I’m scared!!!! Maybe buy the cheapest films and give it a go!?

:lol: No need to be scared, its not very difficult at all. Yes a changing bag is what you need if you can’t completely darken a room.
I have a really dark room with no window in it…would that be handy? I will give it a go, will have a look at your site again :)

Go into the room, switch the lights off and wait a few minutes for your eyes to get used to it. You will then see if any light is getting in under the door etc.
Johnny,
Once you’ve dev’d a couple of rolls, you’ll wonder why you didn’t try film sooner :)
