MAC: http://photography-on-the.net/D30/linear/LinearSharpen_311.sit

Please remove _all_ previous 3.xx versions to ensure the 3.11 runs as expected. I've tried this download on empty PS and it worked, so if you have very odd results, see that you don't have any old versions there.

--

Ok, here's something I'm proud of for a while :)

3.11 uses totally new system for color correction. It's very complicated to edit (to correct e.g. yellow you need to do a whole line of colors basically all over again), but results are technically perfect - no problems like clipping red dots any more. It's also very fast to process. Skintones are very good. See:

http://photography-on-the.net/D30/linear/CRW_0144_LS311.jpg

After feedback from a demo photo, I decided to go for Canon colors first, as that's a good starting point for more artistic stuff. I nevertheless wanted to change gamma a bit (middle gray point is a tad higher) and have some color clearness on the whole image.

Problems remaining are deepening greens (although green tone is now correct, Canon made it darker), and bright yellows can oversaturate on extreme circumstances. Yellows are now very neutral, if you like overall more warmth, use hue/saturation/yellow hue to -3 or hue/saturation overall hue to -3. This new output is very accurate, though, and I'll make a chooser for different kinds of color 'sounds' later.

This version has features:

- sharpening in HQ or non-HQ mode (fast mode). HQ mode (which I prefer, worth the wait) uses the aliasing improvement by resampling - it's slower but you can see the quality difference to non HQ: in areas e.g. which are near bokeh edges sharpening is significantly better and more constant.

- 4 different levels of sharpening for each ISO 100-200 sharpening method

- both sharpening methods have a 'chooser'

- sharpening methods has been improved a lot (to LS 2.1 derivant) to get rid of halos

- ISO 800 sharpening has now also a low quality mode, and is very fast.

- The resulted photo is now in AdobeRGB mode for your convinience

- Add Saturation - high quality saturation adder

- grayscale chooser (3 different outputs to snapshots)[/b]

Hope you find it useful. All feedback is welcome.

As always,

You ROCK Pekka. Thanks for all of the time and effort that you have given.

Just for thoughts, it was you that inspired me to be a better photographer.

Have a great day!!!

Pekka,

Looking good. FYI and anyone else trying out HQ sharpening. You still have references to 3.09 in the play action statement for "more aliasing 1" on the normal, high amd xhigh HQ sharpening options.

If anyone wants to know how to fix it, just select the incorrect statement, click the record button and play the "more aliasing 1" action. Stop recording then delete the 3.09 statement. You can then duplicate this new step and move the copies to the other actions.

Regards,

Pekka,

Very nice!

You have obviously done a lot of work on the colours, and they look good. But I cant help noticing that the 2 curves you use are blowing some highlight detail, will you be updating these in your next version?

Incidentally what are your aims in developing your action, i.e. what effect are you trying to achieve?

Wooohooo Pekka!!! This one is fabulous so far. I just ran a few quick tests and I've got my blues back! I'm excited. Skintones are coming out beautifully, and yellows and reds are quite nice so far. I REALLY like this version as far as I've seen in these preliminary tests. Thanks so much for hanging in there with all our comments and continuing to refine these actions. I think you're onto something! Bravo again. I must do more tests and have a closer look at the new sharpening. ;)

Roger, thanks so much for the little fix. I ran into the 3.09 reference first thing and was about to post when I saw your message. Ran your fix and all is fine. :)

Now, back to some more testing. This is too much fun. I am excited!

Thanks again Pekka!

I haved tried the "convert (high sharpening HQ)", and all I can say is WOWWWW!

Does this means that I can use cheap lens, and get rid of my 70-200IS baby? NOT!!!

The color and sharpness is the best that I've seen.
The color is rich, the sharpness is smooth and clean, very impressive.

One thing though, all of this Linear processing really requires lots of CPU power. My Dual 1GHz, 1G RAM is getting its butt kick. Each image is taking my PC about 1 minute to post process with the "convert (high sharpening HQ)" action. This is fine if you have less than 10 to do, but how many of us shoot less than 100 images per session that we are out on?

Only when I get a Quad P4 3GHz motherboard to do all of these post processing then I'll truely be in Digital Heaven.... for about 3 months :-(

Or with PC so cheap now, we should look into making a Super Computer. I heard that is already been done, and I would like to know how just for the fun of it.
Anyone has Sadam Hussein'e email? The last I heard when the Sony PS2 came out, his people tried to get a whole bunch of them for such project. May be he can show me some tips on building a Super Computer.

It's Friday night...and I need a life. :-), of such is a life of a married man with children (soon) :-)

I've been doing more testing with 3.11. I'm still impressed. Pekka, I think you've nailed it with the sharpening this time. It's beautiful!! The extra high sharpening is too much for my tastes, BUT, it's incredibly smooth. The sharpening action itself is fine, now it's just a taste thing. What you've called "normal sharpening" seems so far to be a very nice all round sharpening. But I just about fell off my chair looking at the extra high sharpening...you really have indeed mastered this one this time...the haloing, or should I say lack of it is simply remarkable!

Pekka, every image I've run through this version so far has come out beautifully. Now, I must add (for the sake of commenting) that I'm finding that the saturation is slightly on the low side overall. But, the extra little saturation step that you've included adds a nice touch of saturation so you've looked after this. And the other thing I'm finding is that there is slightly less yellow/orange/red (or perhaps it's just that these colours are less saturated in the result would be a better way to put it) in the converted image when compared to the Canon output. BUT, that said, I actually am preferring the result your action is yielding over the Canon output. So, for me, it's not a problem at all. Merely an observation.

I like the addition of the grayscale chooser. That's a nice touch. It makes for a very nice, very complete bundled action. Superb work Pekka!!!

THANK YOU!!!! ;) ;)

Pekka, just barely tried out the new 3.11 with the testing night lighting shot. I am trying to post the results later here. AFAICT, it is very close to the color of the scene I see every nite.

Keep up the good work.

This is now corrected in new download from http://photography-on-the.net/D30/linear/

One problem with Canon conversion is that you can never have sharpening totally off - this is a problem when upsampling a lot. Without sharpening at all you can upsample to 100Mb and get a very film like results. Additional sharpening works best when the original in not sharpened at all.

Other thing is general muddyness of Canon colors. They are like that merely by a choice of some developer in Canon, and are designed to fit sRGB color space. As D30 stores 12 bits per channel you can get wider gamut of colors (than sRGB can store) out of it.

It's like a high end audio system: you have a great recording and play it back with a bad preamplifier - it does not matter if you have Genelec 1031's they'll sound like the bad preamplifier. Put in a good pre and you'll be amazed what can be heard (been there, done that).

Basically, I've invested a lot into D30, and I try to see how much and what you can get out from it.

There's a corrected download at http://photography-on-the.net/D30/linear/

It also fixes one curve which killed highlighs in some extreme cases.

Puhleez, Pekka! I feel like all I'm doing is cleaning Picasso's paintbrushes. :D

I have now doubt you'll carry on looking to improve LS. We'll probably see V3.13, 3.15 and 3.23 by the end of February. :) I've spent the morning running different images - some old, some new - through 3.11. I have not been making a systematic comparison to previous versions or alternative processing options. Whenever I have checked an old version, 3.11 has been unquestionably superior, but I have just been running the HQ conversion and looking at the output on my monitor. No doubt, some picky sod will complain that the blues are slightly off :) , but people I show my images to won't say that. They will just be amazed at the quality of the images that the D30 can produce. I will know that, in large part, that reaction will be due to your effiorts in developing LinearSharpen. Pekka, the output from 3.11 is jaw-droppingly good, thank you, thank you, thank you.

Kindest regards,

Roger

Good to hear you like 3.11.

I'll have at least a couple of week break with LS developement now, as I have to put Exhibit Engine out and before that I have to finish updating four websites - and we'll have a really tricky Esa Pekka Salonen concert next friday.

Also, changing small nuances in specific color of LS 3.11 is very time consuming as the whole thing is so complicately built from bottom to up (even small changes affect histogram, other colors etc.)

Since you have tweaked this action for the D30, do you think it can be used for the 1D files as well?

Just checked in the other evening and saw 311 was out. Tried some tests this morning and........WOW!!! This is your best yet Pekka, and like Roger, I've been with you from the start.

311 sharpness (especially in HQ) is just superb, better than my beloved 2.1 ! and sooooo smooth. Colour balance is wonderfully neutral, an excellent base from which to start warming up/cooling down if required, safe in the knowledge that the base colours are nailed at the start. I really am so impressed and I think if a colour chooser (warm/neutral/cool) was also involved in a future version (which I think you mentioned a few days ago in the 3.9 thread) it would be like Christmas every day! ;)

If you are ever in Yorkshire UK, e-mail me, I owe you many beers for showing us how to get the best from that lovely piece of CMOS in the D30.

Cheers Pekka, take a well deserved break!

First, here's is a page of the same pic done with Miranda's and Pekka's actions:

http://www.jackzucker.com/D30.htm

My comments are:

Pekkas action is still blowing out red highlights. Notice the highlights in the red tulip and how they almost have a neon quality to them. Fred's action is truer to the original scene. I'd also like to be able to run Pekka's sharpening alone without the conversion...

Jaz

ratsey
23rd of February 2002 (Sat), 09:59
I like this new action - the sharpening is excellent, much better! I ran some tests against Nik! Sharpener Pro and I'm pleased to say that I think Pekka's may now be better.

Jaz - if you want to send me the tulip image I'll run it through Nik! and you can post that comparison too.

Good work Pekka!

jzucker
23rd of February 2002 (Sat), 12:57
I wish pekka would include a "sharpening only" set of actions. I like his sharpening better than Miranda's but at this point I still think Miranda's conversion is truer to the actual colors...

Keep up the good work pekka! It's getting closer and closer! :-)

I find Pekka's conversion more accurate in some cases, Fred's more accurate in others, and in still other cases Canon's RAW conversion closer to the original. As well I have images that defy accurate conversion! It's not too different from film photography, where the various films have different properties that make them more useful in some situations than others. The advantage we have is choosing our poison after the fact!

I, too, am finding Pekka's sharpening actions superior to anything else I have tried. I found they it can be run independently of conversion in v 3.05. Under the "these a's for internal use" button, click on "more aliasing 1" and then "low", "medium" or "high". Works nicely.

After lurking for a long time i felt i had to get on this board to say thank you pekka, 3.11 is big leap forward on the sharpening front, it is right on the money. I am really blown away with the images i am now printing.

But, well there is all was a but, i normally use fred's SI action to upsample the images i print, how can i do this with 3.11 i really do not want to lose the sharpening in 3.11 as it is that good, but i do not really want to upsample after sharpening. Any ideas.

Again great work pekka, thank you.

Jonathan,

One answer to this one is to use SI before running LinearSharpen. This does work, but can give memory problems with HQ sharpening as the antialias steps then tries to 3x upsize a pretty big image file.

Pekka: does the upsize-downsize still have benefits on an already upsampled image?

I think a bigger issue is that, in my experience, an upsized image needs stronger USM settings than a standard D30 image. I tried it yesterday with 3.11 and the upsized image even with extra-high sharpening was still too soft. Still, there's no reason why you can't add more sharpening with USM, EdgeSharpen or whatever your favourite tool is. With some experimentation, it should be possible to tinker with Pekka's settings, which would be preferable.

Great stuff, Pekka! Thank you for sharing.

I haven't been able to try 3.11 on an image with good skin tones as yet, but I would suspect that the better the white balance of the original image...the better your action(s) will work. I'm anxious to give it a try.

One question...the extra saturation actions...are they meant to be run before or after the rest of 3.11 has done it's magic?

Thanks again...

Correct. It works best when exposure and WB are correct.

If you LS an underexposed photo and use levels to bring it to normal, you'll need to pull saturation back otherwise you'll get too strong colors.

One question...the extra saturation actions...are they meant to be run before or after the rest of 3.11 has done it's magic?

After.

LinearSharpen is an action, not a plug-in or filter. It goes into the the Presets/Photoshop Actions folder. Then you must load the action into Photoshop. See Photoshop online help for details.

Before I send you the originals, here are some results:

1. 16-bit Linear straight out:

2. Use Fred's D30 Linear Pro w/ no sharpen, normal saturation

http://www.pbase.com/image/1236082.jpg

3. Use LinearPro 3.11 convert only + slightly more saturation

http://www.pbase.com/image/1236083.jpg

Hope it helps.

That can happen if the image has a colour space profile attached before you run LS. Did you open the file and start off with no colour management?

Hi Roger,

Thanks for your tip, i will give it a try tonight, but i am sure it is something that a lot of people will come across, i.e. if you want to print A4 borderless you are going to have to upsample or print at a low dpi. So i am surprised more people have not mentioned it.

BTW the prints i am doing at 300 dpi which is about A5 size, are excellent and the sharpening is what i have been looking for since getting by D30, possible the sharpening actions could be used seperate to the conversion action ?

I was at the focus on imaging show yesterday at the NEC, and had a look at the new canon s900 & s9000 printers, very very good, and the speed is something else, also they reckon they use a lot less ink than the epsons, will have to wait and see on that one.

Pekka, I may be getting poor results because of not setting 311 to what I want to end up with.

I want normal sat, sharpness and contrast and end up with sRGB as I find I get better prints in sRGB than adobe. What setting in 311 should I have checked or uncheched to get the desired results?

Hi Dale,

Camera settings have no effect when working with linear TIFF, only white balance matters. I haven't done (yet) any saturation or contrast versions into LS, only sharpness level can be choosed, and saturation added later.

Please post a demo photo(s) of your problem - it's easier to discuss with some examples.

Bigger PC's :D

Actually, I managed to process the image I bombed on, but only because I decided to crop it first and shut down anything else on the PC. Try the non-HQ version, it might be acceptable, but I did find that I had to add further sharpening to my upsized image in any case.

This is really for Griffin and Anthony and those guys who complained about over-saturated reds and pink skin tones.

Since I've been confined to quarters with a slight cold, I decided to have a play over the last couple of days to see, if I could come up with something.

Now I hasten to say that I'm not trying to steal Pekka's thunder in any way. I'm sure he'll come up with a new version, but he has said he's pretty busy at the moment, and what the hey? It's my time to waste. :D

I've posted a write-up of my experiments on my site here:

Interesting findings Roger!

I have been using DonRGB & Kodak’s ProPhotoRGB for my G2 Linear Conversions, and have had very favourable results, link below if you are interested.

I am going to apply my G2 Beta 18 action to D30 files tomorrow to see what sort of results I get.

Hello Pekka,

Many thanks for sharing you hard work with us, your action is for me producing the best results I have had since I started with the D30 last August, yes I do have to reduce the saturation on red, and sometimes on yellow to tone down green foliage, but thats nothing compared to my experience scanning film - could never get colours to look like these! somehow your action also produces clearer, cleaner looking images, I had thought Freds LP action worked well before but they now look hazy compared to yours.

Many Thanks

Sean Palmer

I actually reduced the yellow saturation by 18 to the plant.

Hi Pekka, thanks again for your great work.
Yesterday I took some hours to check the colors with a standard color card .

I could found that the reds are a little bit too strong and the green are a bit too bright. This result I could find also on a picture taken at carnival.

Skin tones are OK.

No question the sharp action is perfect.

Roger,

Thanks for your very comprehensive subjective tests. I agree that the implementation of BestRGB certainly produced more 'natural' looking reds and this is worth further exploration.

Thanks for the channel mixer tip, I shall use it in the way I used Pekkas original "aftershave" action for LS2.1 - this too corrected over saturated reds.

Here's to 312!!!

This version has features:

- sharpening in HQ or non-HQ mode (fast mode). HQ mode (which I prefer, worth the wait) uses the aliasing improvement by resampling - it's slower but you can see the quality difference to non HQ: in areas e.g. which are near bokeh edges sharpening is significantly better and more constant.

- 4 different levels of sharpening for each ISO 100-200 sharpening method

- both sharpening methods have a 'chooser'

- sharpening methods has been improved a lot (to LS 2.1 derivant) to get rid of halos

- ISO 800 sharpening has now also a low quality mode, and is very fast.

- The resulted photo is now in AdobeRGB mode for your convinience

- Add Saturation - high quality saturation adder

Pekka,
Should the saturation be applied before or after the sharpening?:)
Thanks

I tried 3.11 last night on the only raw file that I had created since I got my D30 in December. My previous attempts at turning that raw file into a decent picture were dissapointing hence my decision to only shoot jpegs. However...... 3.11 changed all that! I was stunned by the colors and smoothness - until I looked at my dark wallnut picture frames which were no longer dark brown but light brown/red/orange! Disaster!! The jpeg that I took at the same time showed the correct picture frame color (but everything else looked crappy compared to the raw at high magnification)

I'm going to reshoot that photo tonight using the tips that I've learned during the last few months on this forum (and a few others) to see if the problem reappears.

At one point last night I had the tiff active as well as the jpeg for comparison. I was highly amused when 3.11 started work on the tiff as instructed then proceded to chew up the jpeg!

Any tips on how to placate my wife while I'm spending so much time on the PC?
cheers
Stuart

I have tried to post a couple of samples by linking them to pbase in the message but they don't load.


Are you a PBase "supporter"? That means have you donated any money to PBase? I asked before but there was no reply. Appearently, if you do not send money, no direct linking of pictures is possible.

Hope this helps.

I was waiting for the fee rate to be published by Slug. This the first time it hasn't worked for me, must be something he has just started. :O

Please post a demo photo(s) of your problem - it's easier to discuss with some examples.

I have gotten so use to seeing :eyes my photos with a lot of contrast that I thought 311 created washed out images. I take it back, 311 actually brings out more detail as can be seen by the two photos I posted. The blues in the sky are still a bit off but you are getting close. Thanks for a great action file. Looking forward to v3.12 or v4. :)

I have been looking at this problem further. I think I have narrowed down where this occurs.

Thanks Roger,

3.12 will have only _one_ channel mixer step - I have some very promising versions already but it'll take a few more days to complete.

Can you mail me that flower photo (RAW+THM) for test purposes?

Could I send one of mine too?

I am removing the files on the links I emailed to you earlier.

Griffin,

I've got your "guy with the camera photo" here, thanks.
If you have any other "revealing ones" please send them in.

Pekka,

I think the links are in your inbox already. It is a flower close-up, and it is pink but I see no problem with this one so far.

Thanks for your kind attention.


Regards,
Griffin.
