I have personal experience doing this with a few developers, most recently Ilfosol-3 and Ilfotec HC.I would use the HC as a single-shot developer if you are pushing, perhaps you could squeeze out two uses. In experimenting with reusing single-shot Ilfosol, I noticed similar results with reusing HC that had been involved in push processing. Neither of those ...

Building on Romeo's answer: You can use imagemagick to convert to HSV color space and get statistics on the color distribution. HSV means Hue, Saturation, Value For a true grayscale image, saturation must be constantly zero. You can use the following command: identify -colorspace HSL -verbose <infile> and obtain something like the following ...

With imagemagic you can use command identify to get info about the image identify -verbose image.jpg From the output you can check for standard deviation of red, blue and green. For grayscale images the should have very close values (theoretically equivalent values) P.S. You can check also this site for some scripts for such tests

You could start by converting the image to grayscale and compareing that to the original image. If the image is already black and white, you'd expect the two images to be very similar; if it's full color, you'd expect them to be different. Clarification: Given the two comments below, I think I wasn't clear enough here. Certainly, the grayscale version of a ...

Your best would be to find a PictureStyle that fits your needs. There's a QuickGuide to Picture Style Settings and Customization pdf that will get you started. It is from the Canon Digital Learning Center.(http://usa.canon.com/dlc) I'd like to quote from this article that's about the adjsutments specific to your camera in the following: Find the Picture ...

I think there is a missconception of post processing. Adjusting Camera settings is doing a post process but not done by yourself, but the camera. I don't imagine a camera that renders a black as that one in its raw file. I think there is a need to have "pure photography", which is good. But you most likley don't have that in a digital world. You also ...

You can use it, but it will upset your replenishment schedule. That's why they don't recommend it for reused developers. You can always treat it as a one-shot developer, though - if you have no plans to replenish a given batch (let's say it's been used and replenished already, and is approaching its limits) pushing is no problem, but getting a batch back up ...

If your camera supported custom tone curves, you'd be able to get a similar result to this straight out of camera. Unfortunately, yours doesn't, so your only option is post-processing. There are many ways one would get this effect in post. Basic levels adjustment - put the black point output as a value above 0 using a levels control or similar in ...
