What works even better is converting with a gamma 1 profile as
camera profile and output to a widegamut gamma 1 profile as
workspace, output as 16-bit TIFF. Do all your processing (USM,
levels, saturation) and only convert to gamma 2.2 sRGB JPEG when
completely done.

Thanks Mike... I sometimes output to 16-bit TIFF before doing any post processing, but not unless I have a special one I really want to play with. I did try various color profiles using your workflow you were developing, but I wasn't thinking specifically about purple or colors being clipped. I'll try the wider gamut profile tonight and see what I can get. :)

For the Pro1 I use the Canon D60 as camera profile and the CIE
widegamut gamma 1 profile as workspace profile. Both can be picked
up at http://www.aim-dtp.net , a site that also has an incredible
amount of tips on improving workflow. Highly recommended reading.

Turns out that's the site where I first ran across dcraw! Very informative.

Sometimes I am "lazy" and either use the Pro1 generic profile that
came with BibbleLite and output directly to sRGB, or I use "
straight" dcraw without the -p and -o options, but I can see the
difference in the resulting JPEG.

Hehe... "Lazy" is relative. When I'm "lazy" I just use ZoomBrowser and finish up in PSE. ;)

Nice idea, this purple thread. Some stunning examples to be found

Thanks... yes, I'm always amazed at what beautiful work everyone here comes up with!

Hi Rick!

Those are great. Just goes to show you don't have to lug around the biggest most recently announced gear to come up with some very colorful lovely shots. :)

This last one of sunflowers - the leaves really had a deep purplish

Wow, that one was wild. Thanks for sharing!

Hello Mark

Thank you for your comment. Yes, the S230 is ancient and everytime I shoot with it, I'm not sure if it's focused or not - I just rely on the small beep and a green rectangle so a lot of the time it is hit or miss.

Hello S Hess

Beautiful color and great composition. I like the repetition of the diagonal step and a similary shaped shadow cast upon the wall - which draws your interest. Also, the shadow adds another shade of purple to the image. Great shot.

I used to think there was just purple and now I know there are zillions of colours iincluding Indigo and Violet. Well, we all studied the spectrum and rainbow but we never really refer to indigo and violet except for the flowers. It is very tricky capturing those colours accurately. Anyone who has tried to capture Tibouchina flowers knows what I mean. The camera will get them red to blue and everything in between. The minus EV setting is crucial in Violets and I even had to go as low as -2 to capture a violet colour more accurately. The same goes for bright reds. You need that -2/3 to get detail instead of oversaturated blurring.

I can't say which colour is which but I hope they all fall under the purple category!

















 
Hello Vince!

Glad you joined in! Wow, some beautiful flower and color shots :) It very well may have been from you that I picked up the trick of lowering EV for strong reds and purples. It really is invaluable. Great job as always... Thanks for sharing!
Best regards,
Mark

LeeJay Finger and others pointed out the minus EV and it makes a big difference. Now I know why Canon put that button so close at hand. I never used EV before but now I play with many images including sunsets and clouds.

I can't wait to try those minus settings on Jacaranda blossoms and Flametree buds. Bright orange-red flowers are anther problem and I never could capture them properly. It is quite staggering how a name like purple can represent so many very different colours.

Indigo violets were the most difficult to capture for some reason. That dark, almost blackish purple just doesn't want to appear on the LCD or monitor.

I haven't played with white balance but that is worth a tickle, too.
 
The problem is not the sensor. It is the processing which is often toward "Pleasing" color rather than accurate color.

In this shot(sorry nothing pretty Maxell DVD cases):
http://i.pbase.com/o5/04/606404/1/67358179.KACn5xrl.ColorComp.jpg

I pulled the embedded jpg, did a canon raw conversion and an ACR conversion.

Result. Canon pushes purple to BLUE, both in jpg and in its raw converter (RIT). ACR renders it accurately.

So if you have a purple problem or suspect a purple problem. Shoot raw and use ACR.

Note no PP or adjustments to any image their, all straight from the jpg or default converter adjustments.

So I wanted to say the purple problem is real, but easily dealt with.
 
Hi Peter!

Thanks for posting. Very interesting comparison... Even with RIT the minus EV setting helps that quite a bit (I assume because of color clipping in sRGB). There's a good reason ACR is the most used converter :)

Here's another purple for you processed with ACR:



Best regards,

I try to keep all my camera's on minus EV. It makes a big
difference. Very nice stuff here. Thanks for posting.

Yep, it seems to be a big help especially for oversaturated reds and purples (besides avoiding blown highlights). Thanks!
Best regards,
Mark

I really don't thing color clipping is the issue. Here is a more clearcut example, nothing is near being blown. Every coverter I ran this through came out the correct purple except Canons.

I think this is a choice. Canon decision to make Blues very blue. Impacts correct color rendering.

I have noticed that sometimes purples do actually come out much better using a wider gamut color space (even just Adobe RGB can make them suddenly purple again). Interesting that the other converters are able to come up with purple instead of blue! Nice example. Thanks for sharing! :)

I'm sure it must be their choice. Blue skies are more frequently photographed than rich purple, so I'm not surprised. Sometimes Dave Etchels runs an imatest on color reproduction over at the Imaging Resource (testing the internal jpg generator's color). Interesting to compare at least. Here is his comparison of the color reproduction from the original Rebel with the Rebel XT:
