ISO mistake, advise to correct in development - B&W

[luis_modesti]

<p>I was shooting ISO 100 film and spot metering with hand held Light meter. I had my light meter set to ISO 100. all good. I was metering middle gray so I expect my mettering to be accurate for my scene. Then I decided to switch to another film at ISO 400 but forgot to set my light meter to match the ISO. I shot almost the entire new roll metering with light meter set to ISO 100. The camera however was set correctly at ISO 400. This means that I am pretty much ~two stops overexposure for most of the roll. I was shooting Kodak Tri-X 400 . The scene I was shooting was an overcast morning with very dense fog at sunrise. Light did not make it through the fog, so in general it was a low contrast scene as it was. </p>

<p>My question is: How can I correct this mistake in development ?. I think the answer is PULLING two stops during development assuming I still have detail in the highlights. As I am no expert on this, I'd like to get some advise. Is this the right solution. ? I believe I have to lower development time to accomplish this, but this will cause lose of contrast, right ?. I am hoping not to lose too much more contrast due to already low contrast scene as described above. Should I pull one stop only ? then I am thinking I will need to use a higher contrast paper/filter to increase the the contrast during printing ? I print on VC Ilford B&W paper.</p>

<p> I also heard of intensification and reduction processes but not sure if that can play a roll here ?</p>

<p>These should be good images of the Everglades in Southern Florida. I have to do what it takes to rescue the images.</p>

<p>Thanks in advance.</p>

<p>oh I forgot to mention, I use Kodak D-76 developer as my standard developer. Not sure if another developer could help this ?</p>

<p>Is the camera a completely manual camera or an auto exposure set to manual mode so that the camera ISO setting has no effect on exposure?<br>

If yes, I would cut development 10% from normal for box speed.</p>

<p>If you have over-exposed by 2 stops then reduce your development time by 50 percent from the 400 ASA dev time. For example, if the dev time at 400 ASA were 12 minutes, the give it 6 minutes. The resultant negs will be low contrast but you can recover that in printing.</p>

<p>My normal method is to cut development by about 25% per stop over exposed.</p>

<p>So for two stops, 0.75 x 0.75 x normal development = 0.56 x</p>

<p>Can Kodak HC-110 developer help ? ot should it no matter sticking with Dektol. ?</p>

[luis_modesti]

<p>sorry, I meant to say D-76.</p>

<p>my question is . Can Kodak HC-110 help in this situation. ? </p>

<p>You are going to have to use N-2 development for this and hope for the best. Your highlights are going to be pretty blocked but you might wind up with something useable.</p>
