I am a BB user now and I will be downloading the trial version C1 LE tonight. I will do a side-by-side comparison between the two using selected images I just took of golden poppies today near Lancaster, CA. I hope that I can post the results in the next couple days....

Phase One is aware of the highlight restoration issue and they will have a fix.

Any word on when to expect this fix to be released? Being a long time user of BB and YarcPlus IMHO C1LE is better now and will only get better when the bugs are ironed out. However if and when Canon fix the linear process in the SDK Pekka will I'm sure have another version of LS out for the 10D which will be very good.

The following is a very interesting comparision of BB and C1LE by Roger Cavanagh.

The highlights fix should be out w/ RC2 later this week.
Also, I undersand that Pekka already announced that his workflow will now include C1-LE and that he will modify his actions to support that :-)

i'm using breeze. should i not use linear conversion with it? how about their combined conversion?

If you have a 10D, then the linear conversion will not give good results. There is a bug in the Canon SDK that converts to 16-bit linear, but only uses 8-bit data. the edits necessary to give a usable image cause severe posterisation. Since the combined conversion uses linear it will be also affected, but presumably to a lesser extent, but I have tested it.

I have switched from BB to C1LE. While there is an issue with blown highlights, its possible to remove 95% of the highlight details with exposure compensation.

Aside from that, color rendition is better and RAW conversation looks better with C1LE than with BB.

These two gallers were processed with C1LE and final adjustments done in PS6.

The TX State Museum were handheld at ISO 800 and 1600, sometimes being pushed to ISO 3200. With C1LE I was able to recover 4 or 5 images I thought were not usable, even for the web.


Take care,

Is there somewhere I can go to learn more about linear conversion and that 8-bit & 16 bit thing...

And while I'm here, what's the business with Colour Space? You know, where you set your camera for RGB or sRGB and so on.

Martin,

I don't really know of a good place. Basically, it's pretty simple to understand. The linear conversion is the closest representation to the way that the camera captures image data. Linear images are dark because the photosensor doesn't react to light in the same way our eyes do, so linear images must be gamma (think of it as brightness - that's not quite right, but good enough) adjusted so they look "normal".

The theory about using linear conversions is that you'll get a better result using Photoshop because you're starting with "cleaner" image data than if you leave it to the conversion program.

And while I'm here, what's the business with Colour Space? You know, where you set your camera for RGB or sRGB and so on.

Colour management is a complex topic and I don't pretend to know all about it or even everything I should. There are some good links on my site:

To answer your question as simply as possible. Adobe RGB has a wider colour gamut than sRGB. sRGB is the best colour space to use for web images because it's smaller and most monitors will display the colours OK. This basically means you have a better chance of other people seeing your pictures the way you want them to be seen.

Personally, I'd rather have the extra colours of Adobe RGB vs sRGB, but using Camera Raw or Capture One LE I prefer to convert to ProPhoto RGB, which is an even wider colour space.
