Developing C-41 film with 'pushing'

[ciaran_mcmenemy]

<p>hello!<br>

Today I took some photos, but all I had available was 200 speed. It's cloudy as usual here in the UK (a whole week of rain? well that's something new), so I set the camera to 400. <br>

How can I compensate for this in terms of development time? Assume that I'm using a press kit with a 'normal' time of 3:15. maybe I need to make it 3:30? just a guess. <br>

Sure, negatives can be scanned well for varying degrees of exposure, but I'd like to have the negative itself as the 'proper' image. <em><br /></em><br>

Thanks for your time.</p>

The kit directions may have pushing guidelines. Some color negative films respond better than others for push processing.

<p>oh wow, I forgot to mention that it was colour.<br>

Very silly of me! I'll amend the title.</p>

<p>The title has been amended to C-41 by the moderator..</p>

<p>Kodak has times for Porta 800 pushed one and two stops:</p>

<p>http://wwwde.kodak.com/global/plugins/acrobat/en/service/chemicals/cis211.pdf</p>

<p>They are 3:45 and 4:15, respectively.</p>

<p>Normally there are also times for successive rolls in the same chemistry, but this one seems to say not to reuse the developer. I wouldn't save the developer, but only reuse it in the same session. <br>

I believe that there are Kodak documents that give the times for additional rolls.</p>

<p>I would go for 3:45.</p>
