So blue/cold?

Darryl Roberts · May 15, 2019

Hi,

4x5 with 160 Portra, why are all of my shots so blue?

What is the color temperature of your lamps and the intended color temperature of the film? It they match, then perhaps a development error.

Is it the way you're converting the negative scans into positives in software? If not, that's an easy way to fix it.

Light was Profoto D1000

Thank you. I didn't scan it. It was North Coast Photographic

Looks like they did a bad job inverting the scan to a positive. Your light and your film are both daylight-balanced, so it's not a fault in the shooting.

If you got back TIFFs from them, you can try to pull out some blue using the curves tool in your favorite image editor.

Kodak Portra 160 4061 is a COLOR NEGATIVE film, so the scanning process converted the negative image to a 'color transparency' interpretation of the negative image. It is entirely the fault of the scanning process! The lab might have assumed that the image was taken under constant light source (warm) rather than strobe, and the automated scan software therefor cooled an assumed warm lighting.
Any digital image processing software can easily fix it. Here is one example...
