Possible N0ob question...

[jemdna]

Hey everyone

Say I want a slightly grainier image... (Read extreme )

I usually shoot with DX Encoded ISO 400 film,... would I set the camera to ISO 100 for example for grainier images or the opposite... 800?

Also does the cameras metering system compensate for that OR do I have to make sense of it?

Cheers

Opposite Bry. 100 is silky smooth and 1600 and above rough as a badgers! (Usually)

You could try shooting at normal ISO's and adding the grain in photoshop. The problem with digital is that it does not behave like film with grain, it produces digital noise which can be rather ugly.

And yes you would have to make sense of the metering as the increase in ISO makes your sensor more sensitive to light so it affects your exposure.

set it to 800 and then increase the processing time, the metering will behave as it should and underexpose. You'll have to do the whole roll though or you'll end up with a right mixture

So...

Set CAMERA to ISO800 with ISO400 Film...

Then compensate by approx <Value> stops lower when shooting?..

This would result in a grainier image?

I don't process my self (at the moment) I usually get my friend at the local jessops to run them through for me...

slightly grainier with 400 film set camera iso to 800 and get processed as push +1 stop
grainier still use 400 set to 1600 and pushed +2 stops. That'll be fine with HP5+/400 Tmax for example.

Don't compensate when shooting. Deliberately let the camera underexpose the film.

When processing get your mate to increase the exposure time to get the exposure right. Here's a guide from Ilford

Yep - by setting the ISO on the camera to a higher value, that's already doing the compensation of 1 stop under-exposing the film for you. Then when the film's developed, you leave it in the developer for longer, which over-develops the film by 1 stop, leaving a nett accurate exposure, but larger grains in the film-base by virtue of the longer development time.

Just spoke to the guy, annoyingly, he reckons the "Machine" just does it automatically and so no adjustments to allow it for longer development...

Any way around this or do I just need to wait till I have my darkroom sorted...

send it to ilford and ask them to process it +1 stop...

Cheers for the suggestion TBY, That shall be the plan
