Pushing Efke KB100 to 200

[Krzys]

I enjoy shooting Efke KB100 in 35mm with Rodinal or HC-110 at 100asa and love the results. Several sources say that it can be pushed to 200 'for increased speed and optimum differentiation of highlights'. Well that sounds lovely. It would be nice to gain an extra stop in overcast...and I love a bit of extra grain.

Could anyone share some photos or opinions on Efke at 200, or just the film in general.

It looks like I would be best off pushing in HC-110 however the massive development chart only lists times for 100, while it goes up to 400 for Efke 100 in Rodinal.

The EFKE film speed on the box is the Tungsten speed, the Daylight speed is higher. In the UK Jessops used to sell KB100 rebadged as a 200 EI film

Here's the EFKE datasheet KB21 (DIN) is KB100 (ISO)
