I’ve had the good fortune to travel to some amazing locations and make images in the past month. I’ve used Kodak Ektar exclusivity for my color work because I believe it gives me the best color rendition. However, I am still exploring the emulsions performance in long exposure and tricky lighting situations.
A few observations from my last few shoots. For exposures of 30 seconds or less reciprocity failure is present in Ektar 100 but has a negligible effect. As a photographer I am now more concerned with people walking through the frame close to the lens than I am about calculating reciprocity for 30 second exposures. If you are concerned meter at ISO 50 for safety. A one stop over exposure will result in a denser negative that will scan without issue and is preferred as an aesthetic choice by some Ektar users .
In the previous image posts Grand central Terminal, study 6 (http://www.timothyhutto.com/somebodylovesyou/2019/8/16/grand-central-terminal-study-6 ) & Oyster Bar at Grand Central Terminal (http://www.timothyhutto.com/somebodylovesyou/2019/8/23/oyster-bar-at-grand-central-terminal), I used Ektar 100 in indoor situations. The said scenes were metered at 8 seconds at ISO 50 and exposed the same. After scan & retouch I think the results confirm that an extra stop of exposure for safety will result in a good image in indoor situations.
In the above image Lacoste, Study 88, I metered the scene at ISO 50 ( apx 8 seconds at f/11). During capture I bracketed my exposures (as metered, +1 stop, +2 stops) to play it safe. My best negative (standard lab C-41 development) came from the +1 stop of exposure time ( apx 15s @ f/11 ISO 50 ) and +1 over exposure in my metering, a total of +2 stops of overexposure in a pre-sunrise situation.
The more I use this emulsion in long exposure situations the more questions I find myself with. Is Ektar intensive to cool wavelengths of light? Does that explain the warm rendering of shadows in most situations? Image making with Ektar has been rewarding because it has restored some of the mystery and magic that analog photography enchanted me with when I first began.
