There are two different films shown, both films are a 400 speed color negative material… one of them is the new Kodak Portra 400. Which do you like? These scans represent the outer edge for a 400 speed film… EI 25 and 50 as well as 1600!

I will use the information gathered from both of these posts and your votes along with additional testing I am running for my final thoughts in Part 4 which will be next week.

All negatives were scanned on an Imacon Scanner as a 3F linear file with no sharpening… essentially a RAW scan.

All images were processed exactly the same in Photoshop. All images were captured with my Nikon FM3a and a 50mm f1.2 AI lens.

Tell every photographer you know to vote on this as the results will be very informative for our Figital community and will be covered in my fourth and final post on this review on Novemember 23, 2010… vote now!!

Be sure to Vote now!!!!


New Kodak Ektar 100 vs Kodak 100 Ultra Color

Kodak Ektar 100

This is part 2 of my review of the new Kodak Ektar 100 film- click HERE to read part one. In this test I decided to compare the same scene photographed side by side, one shot with the new Kodak Ektar 100 and one with Kodak 100UC.

Test Specifications:

Camera: 2 Olympus XA cameras both just calibrated and shot at F8, focused at infinity.

Film: Kodak Ektar 100 rated at box speed (100) and Kodak 100UC also rated at box speed (100).

kodak100ucboxScanned on an Imacon scanner (dry) at 3000 PPI so around a 68MB 16 Bit RGB file.

Color Space: sRGB

No sharpening applied in the scan or in Photoshop. All scanner settings were set for Standard RGB Negative with full auto applied.

In Photoshop only AUTO settings were used (levels, contrast and color)- no additional image manipulation was applied. Test files were then down sampled to 8 Bit and reduced to 10″ x 6.5″ for faster download- saved as a JPEG, Level 10.

Please only download the sample files if you have a high speed internet connection as they are around 3MB each compressed.

Kodak Ektar 100 Film TestKodak Ultra Color 100 Film TestMy Thoughts:

The Kodak 100 UC has a better exposure latitude, especially at box speed than Ektar 100 does but the grain is a bit more pronounced and the color is somewhat muted whereas the new Kodak Ektar 100 at box speed is a bit thin but has nice saturated colors and somewhat finer grain. Exposing the new Kodak Ektar at an EI of 50/ 64 will make this film very hard to beat.

Overall both films are quite nice but I tend to like the look of the Ektar best, especially when exposed at an EI of 50/ 64. I find scanning the new Kodak Ektar film quite easy and possible enlargements from a good sharp capture lens and a good quality scanner with a bit of work in Photoshop can produce some amazing quality prints even at sizes up to say 20″ x 30″… remember this is 35mm!

Note: If you want to try this film be sure to rate it at an EI of  50/ 64 otherwise your shadows will be thin and you will not be seeing all that is possible from this new offering. Yes, I like this film!
