When switching from portra 400 to gold 200 I forgot to change the iso for the first 5 frames .
Would those 5 frames (that were taken at 400 instead of 200 ) be in good condition after developing for 200?

C41 has a wide exposure range so exposure can be off for part of the roll and the photographs will be usable. Slide film lacks the wide range so if the exposure is off by more than half an f/stop the photograph may not be saveable.

You do not need to compensate in development unless you are 3 or more stops over or under exposed.
ISO 200 @ EV 50 or lower / 3 stops over cut development time to 3 minutes.
ISO 200 @ EV 1600 or higher / 3 stops under extend development time to 3:30 .
Any speed between EV 64 to EV 1250 use normal processing of 3:15.

In my opinion not too bad but not good. If you were to set the to 200 while having 400 film in the camera I would say no problem at all.

In the late 90's / early 2000's I was taking my color film to The Darkroom in San Carlos, Ca. After a few rolls they told me to cut my film speed in half as they did not need the extra density and box speed slowed down their throughput. Another person on another photo site (photo.net?) was told the same thing by a different lab in the L.A. area.
I only used them for C41 processing and custom prints after that.
ISO 200 exposed at EI 400 will print and scan well.

Basically what that is telling you is The Darkroom uses one generic/averaged setting to scan and/or print all the film they were getting. Instead of wanting to take the time to get your roll right.

Yet another reason not to use them. (they messed up my film a while ago, never offered to make it right so I stopped using them)

It sounds to me that you've exposed 5 shots at ISO 400 , and the rest at ISO 200 .
So from a development point if view , it's irrelevant if the roll was shot at different ratings .
The whole roll will be developed for the same time regardless , it's not like it's sheet film where each shot can be developed differently .

As others have said , the film will come out fine anyway .
I've used cameras without a meter and had to guess exposure . The settings I've used will likely have had at least a 1 stop variance from ideal and all come out fine .
So don't worry .

If we are referring to The Darkroom, once in San Carlos and now in San Clemente, CA... I use them on a regular basis and have never had a problem. I've used them for, both, color and B&W in all formats (except color 4x5).

Interesting. Glad they work for some people.

I tried them out. 6 weeks to get some black and white prints, lost the order a couple of times, after a month offered to "rush" it, and when it got here two weeks later it was -- bad.

I have a feeling they're better at advertising than they are at photography.

Can only speak for myself of course...........
I have used them for the last 5 years for Color Neg and Slides........and some B&W from FPP i did not know how to develop.
I have never had a problem.

Like I said I used the one in San Carlos in the late 1990's to early/ mid 2000's. There were several locations at the time up and down the West Coast. When that electronic recording medium took over photography they closed many locations, apparently all but one. Whether the current The Darkroom is owned and operated by the same owner or not is another question and whether or not the photo pros from 25 years ago are still providing the service or if it being provided by a bunch of clueless youngsters is another.
I was always satisfied with the development and custom B&W and color prints I had made there.
