Lack of orange cast on colour negatives

[ackers8888]

Hi Guys,

I took a batch of 35mm portra 160 to be processed at a local 'professional' lab.

I'm scanning the results and it's obvious something went wrong somewhere. The images are very grainy and de-saturated. They look terrible.

I am comparing the negatives to another batch of negs I shot in May using the same film with perfect results. The perfect negatives appear to have much more of an orange cast to them

The image below is a good negative

This image is a new/bad negative.

Is this likely to be caused by bad developing? Lack of fixing maybe? Any ideas would be great.

Thanks

Claire
