Canon SX30IS profile

Good day all,

I am attempting to create a profile for a Canon SX30IS, and have a few questions.

The camera I have is not a standard SX30IS - it has been converted to take infrared images - I have a cut filter to allow 'normal' images to be taken but would prefer not to use it as I  have an NX300 for those. The Canon also has CHDK installed so is able to take RAW images which the original SX30IS was not capable of.

I went to the Imaging Resources site but they do not have a RAW file for the camera only a .jpg - will this make a difference?

I have an X-Rite colour checker chart, what would be the perils and pitfalls of creating a RAW image for use as a profile creator?

Thank you in advance

Ian

I recommend the Color Checker

I recommend you take a Raw shot of your X-Rite Color Checker at an exposure that you consider appropriate, then create your Raw Tone Curve from that.

Thank you.

Thank you.

I've been trying just that over the last few days using these figures 232, 149, 91, 49, 23, 8. I can set the 232 & 8 easily enough but there are not enough 'zones' to allow selecting the 149, 91, 49 and 23 zones.

I've been following the YouTube video, I've tried varying the exposure but the 8 and 23 squares highlight at the same time when using the zone selector and the 149, 91 and 49 values do not highlight at all in the bottom row although blocks in other rows do appear highlighted.
