Custom tone curves compared
Posted: Wed Oct 06, 2004 7:26 am
I guess it's been a slow day for me. I've been experimenting with custom tone curves, loading them 1 at a time into the camera and shooting the same scene for comparison. The normal tone curve is also included as a baseline. Thought it might be helpful for someone undecided on which custom curve to choose, and don't have the time or patients to do what I did (a special hello to all those unregistered lurkers )
At the moment, my hosting gallery Fotopic.net seems to be down, so I've uploaded them temporarily on Geocities. They don't like direct linking - so you'll have to copy/paste address into browser.
Other camera settings - JPEG large fine, Auto WB, sRGB Ia, med-low sharpening. Images resized in PS7, no further post processing otherwise.
These curves presented approximately in the order taken (judge by the shadow cast on the building).
Normal tone curve - use as baseline

Normal + 0.3EV

Normal + 0.7EV

Alfredo 3 curve - slightly brighter than normal, 244 cutoff (NB: 255 is max light value).

White Wedding v3.5 - +0.5EV over normal with highlights tapered.

Provia v3.4 - supposedly closely matches low contrast tone, but slightly brighter, and with highlights tapered.

Normal - the sun moved quickly, so I took another just to standardise

BH Film curve - a new, very high contrast curve aims to match the look of positive film (shadow details completely lost)

If you want any further details, don't hesitate to ask. If you're wanting to find out more about each curve and where to get them, let me know too.
