Give it a try.

This works alot better with your colour chart Martin!

Dear all,

Please try this Linear conversion action for the G2.

http://www.mechems.co.uk/G2-Actions.atn

1. Load your linear image into PS, do not assign a colour profile.

2. Run action, on the last curves dialog alter the brightness with
the top point.

This is quick and dirty, I will develop it over the next week.

All comments & suggestions gratefully received.

There in lies the rub. I saw the term "linear tiff" but it didn't click that the linear was such an important component of the team. Thank you very much for the patient explanation :o)

Now I get it... and like it much!

W
We are not talking about normal 16 bit TIFF but 16 bit Linear TIFF,
if you need to know about this, open this page and go down to
"Acquire Examples: Linear Acquire".

I don't know for sure, but I doubt Elements can open 16-bit files. Check and see, and if it can... wait, it still won't work because ELements dosn't have a curves dialog, does it? Does it have Hue/Saturation? Unsharp Mask? you need all four of those elements...

W
Has anyone been able to convert the LS action (or something similar
given Adobe Photoshop Elements limitations) into an action that can
be used with Adobe Photoshop Elements?

Thanks in advance

Sorry for this COMPLETELY ignorant question!! Can someone point me to how to use an "Action" in PS? I am still learning - sorry, and haven't got to actions yet. Therefore, I can't comment on the action because I downloaded, loaded it into PS, but now I don't know how to use it. I don't want to take anyone's time with an explanation that can be found elsewhere, so if someone can point me in the right direction, I won't take any more of your time. (Oh, and I did do a search, and couldn't find anything about actually how to use actions!)
I'm sorry, but I don't understand how an action can correct images
taken under different cicumstances.
So, did you read what was said at
http://www.photography-on-the.net/D30/linear/

The main point was the sharpening in linear mode. In addition there
was correction action for D30. Now, I do agree the G2 does very
well in daylight but sometimes one would like to have more control
over the conversion, like for doing the sharpening while still in
linear
stage. This is why it would be nice to have similar conversion action
for G2 as well.

Correcting images taken under different circumstances is something
that many of us are used to. Scanner users have no choice and
digicam users might want to go beyond handful of choices available.

Much better!!

This is Phil's raw file:



I think the next thing you should do is working on the clipping and remove "convert to sRGB", converting to sRGB certainly better for the internet but not for prints.

Photoshop Actions

An action is a series of commands that you play back on a single file or a batch of files. For example, you can create an action that applies an Image Size command to change an image to a specific size in pixels, followed by an Unsharp Mask filter that resharpens the detail, and a Save command that saves the file in the desired format.

Most commands and tool operations are recordable in actions. Actions can include stops that let you perform tasks that cannot be recorded (for example, using a painting tool). Actions can also include modal controls that let you enter values in a dialog box while playing an action. Actions form the basis for droplets, small applications that automatically process all files that are dragged onto their icon.

Both Photoshop and ImageReady ship with a number of predefined actions, although Photoshop has significantly more actions than ImageReady. You can use these actions as is, customize them to meet your needs, or create new actions.

To load a set of actions:

Unless the action file you downloaded was a compressed file (Zip, StuffIt) that included specific instructions, you should follow the directions as follows.

Put the .ATN file in a directory of your choice. It does not need to be in the Photoshop directory.
Choose Load Actions from the Actions palette menu.

Locate and select the action set file. (In Windows, Photoshop action set files have the extension .atn.)
Click Load.

To load a preset action set:

Select an action set from the bottom section of the Actions palette menu. The name of the set indicates the type of actions it contains (for example, Buttons contains actions for creating buttons).

Thank you for your explanation - I so appreciate it! It does show up in the action palette now, but once that happens, you open a picture and click on that action for it to run?

Leezah,

you click in your picture (so that this has the focus), then click on the action, and then click below in the action-menu on the icon (arrow) to start play the action;
Success !

Martin,
I think the next thing you should do is working on the clipping and
remove "convert to sRGB", converting to sRGB certainly better for
the internet but not for prints.
What is a preferred color space when you want to print ?

I thought that all digicams used sRGB as colorspace, so that it was the best to add this color space to the result (tiff or jpeg) ?

Yes... they usually use sRGB as profile but the actual images are much wider than sRGB, so if you convert them to sRGB the extra information will be lost. For G2 I usually assign Adobe 1998, the color rendition is much better with that profile although it's not for every situation.

So I still like Canon's the best, although I can't say I know what is the most accurate.

Cute kids.
 
Hi Martin,

Thanks for the comments, please check that you are loading the Linear file into PS 6.01 without any colour profile assignment(Very Very Important). I do not have a clipping problem with my images.

I have just updated the action again, I had made a big mistake and the Hue/Sat step was blurring fine detail, so I have used a few tricks to avoid this.

I will release the action later this weekend. The images I am getting now are slightly Sharper & more Saturated (Velvia like) over the canon processed image but the biggest improvement is in dynamic range.

Thanks for your input.

An Example:-

1. Image from Canon software normal settings(Note loss of detail in trees)



2. Image from my new CW-Linear Action V1 (Note increased dynamic range & detail, the image is a little dark but the detail is there)



Please remember this is a very small crop form a large picture, also it has been highly compressed.

This is one myth I never understood. How can one RGB space be "wider" than another? 3 channels, 256 shades of grey per = 16.7 million colors. Period. The truth is, AdobeRGB has more "out of gamut" colors than the other rgb color flavors. sRGB has just as many colors, they're just spread out differently. For your home inkjet, it's probably best to use Adobe RGB, but if you want to separate to CMYK for press work, you'll probably get better results with sRGB, Color Match or Apple RGB...

About adding sRGB to the end of the actions, I think it's a mistake as well. I prefer to leave my data unprofiled. When I send to the lab, I convert to AdobeRGB, when I send to the Iris at work, I use Color Match... I just deleted the step from the end of the action.

Anyway, I now understand all this linear tif talk better and am really tickled pink, wow! They dynamic range is the biggest barrier between a G2 and an SLR, afaik, and these techniques bring the two much closer together, at least to my eyes (and my histogram and info palette in Photoshop)

Two examples here. The highlights and shadows are clearly better defined than the versions I'd created before by simply going from RAW to jpg or plain tif. I thank you all very heartily for bringing this up in this forum and a big hug and a pat on the back to Pekka!

Larger versions wher ethe detial is easier to see are here:

The linear portion works well but I am running into problems with the sharpen part. The Hide Layer "Fond Copie" doesnt work. I get an error message saying that layer "fond copie" not currently available. The same error crops up later when you Select Layer "Fond Copie"
Tell me if I am doing something wrong.
You should redefine the curve, that way it will work.



Martin
 
He's not running Photshop in english. When you run into that problem, you can double-click the targeted layer and re-name it "fond copy" then continue the action...

Good Luck,

Oh, actually I should mention to cocorico that he can run Photoshop in english by removing or renaming the file called something like "tw10428.dat" in his main Photoshop folder. In Photoshop 6, they moved it somewhere else, I forget wher eexactly, but it's there as well...

hth,
