Luminosity and saturation blending modes in FW CS4 differ from their equivalents in PSE 7

Example:
Upper bitmap is filled with RGB(232,168,89) color and the lower with RGB(61,114,158) .
Blending results are as follow:
Luminosity in FW CS4: RGB(67,121,175)
Luminosity in PSE 7: RGB(137,190,234)
Saturation in FW CS4: RGB(60,109,158)
Saturation in PSE 7: RGB(41,119,184)
I think PSE uses chroma as saturation and luma Y' 601 with gamma compression (2.2 or 1.8) as luminosity.
So it's compatible with PS. And what about FW. Does somebody know how FW works. I was experimenting with
HLS and HSV and wasn't able to find it out. Maybe FW's modes are better in some web cases, I don't know.

What happens to your blended colors in PSE if you turn off the color profiles?
Fireworks is intended to produce graphics for display in Web applications, which have only recently begun to support color profiles. Even then, you don't want to use them on your page graphics (like nav buttons), because the profiles won't apply to HTML/CSS colors and you'll get mismatches.
PS is primarily intended for photographs and for printing, and so the standard workflow in PS (and I suspect also PSE) is to apply at least a default color profile. One use of color profiles is to correct the colors for printers, but profiles will also change the colors in images.

Saturation Blend Mode Does Not Perform As Specified

This question was asked two days ago by another poster on the Photoshop Macintosh Forum. There were no responses, so I am re-asking the question here.
According to ALL authorities out there, the Saturation Blend Mode is supposed to produce a result having the saturation of the blend color. It does not consistently do so (and the inconsistencies are not limited to gray areas). Why?

Hi,
Thanks for the answers,
yes the two vlans are just switched on the catalyst, they enter into the routed process with the other layer-3 vlans.
The default gw of the servers is the csm (the alias ip). We are totally sure there is not an asymmetric routing, the vlan servers talk with other vlans only by being bridged by the CSM.
We tried a similar catch-all configuration in the past days, now we'll check your last configuration: our aim is not to lose "src port" infos when the ACK comes back from the server to the client. We saw that nat client/natpool work as a PAT.
The other problem we had with our original catch-all configuration (listed below) is that we can't have two of them for different vservers/serverfarms (VIP) on the same vlan. We'll check it and we'll let you know
Our "check-all"

Hi Mathais,
I assume you have installed the OPC enum services in the same machine where xMII UDS is running.
Also make sure that the browsing mode is set to true in the OPC Server.
We had the same issue...and were receiving the same error...but once we changed teh Browing mode at teh OPC server to true, tag quesries started working....
Hope it helps...

Color Dodge Blend mode issue in CS4

Alright I'm running CS4 and I'm having an issue using the color dodge blend mode for my brushes. What im trying to do is to create a light effect which I've done this before and I've also run into this problem before and I've solved it but I just cant remember how. I have a dark gradient on my background and i created a new blank layer for my brush, i set the brush layer blend mode to Color Dodge and use a white brush so it will pick up on the gradient. The issue I'm having is it's just painting over the gradient as if nothing is there and it only starts picking up on the background on a ring that I uncover when I go over it with a brush I'll try and provide an image. the white is suppose to turn bright red when it goes over the colored part of the gradient but it only changes its color near this ring on the gradient that I didn't add in. . . it's a weird explanation and I'm sorry cant explain it better but I hope someone knows or can figure out what I'm talking about or experiencing. your help is appreciated

I tried what you said and overlay wont work because it's too dark. I don't know if it was something wrong with my brushes or something else.I opened an old PSD that i had done this same thing with and the color dodge was working on that but whenever i created a new one it would act strange like the image above. then i tried again later and for some reason it started to work. The only thing i did differently was reset my brushes and i created a group and changed the group's blend mode to Color Dodge then put in a blank layer inside the group folder with a normal blend mode and it worked for some reason. I still don't know exactly what i did but oh well it's working now. Thanks for your help. This is what i was trying to do so now you can see how it wasn't working above.

Flattening Blend Mode/Layer Effects CS4

Greetings,
Working in PS CS4 Mac 10.6
CMYK document with a simple image layer with Drop Shadow layer effect and blend mode: Overlay.
I can't get the layer to flatten! When I try to flatten, it ends up looking like the original layer without blend mode or drop shadow.
I'm using the method of creating a new empty layer above image layer and merging the two together.
Is this unique to CMYK mode? (I usually work in RGB mode.)
Any suggestions?
Thanks!

an additional layer with a stroke
Are you sure they want a stroke and not a Path?
Hard Light seems to be pretty much the opposite of Overlay, so you could try
• duplicating the background Layer,
• setting it to Hard Light,
• Clipping Masking it so the the Layer in question and
• setting that to Normal –
that should then be able to be merged.
The Drop Shadow however would of course lose its Blending Mode if it is merged to the Layer.

In terms of efficiency and expandability, how does iPlanet Portal software differ from a portal written in PHP and PERL?

In my opinion the fact that the portal uses primarily JAVA, lends itself to quite a bit of expandability. I think it will be quite difficult for a portal written in PHP (Such as PHP Nuke) to share user session and state information accross multiple machines/instances. The iPlanet portal server has been designed to accomodate this, through the use of specialised session services. The threading model in Java also lends itself to greater efficiency when executing multiple tasks, whereas a portal based on PERL, would have to start a new process everytime a service is requested, which can then become VERY resource intensive.
In terms of expandability, the fact that it is contaned inside a JAVA VM will allow you to develop and deploy alot of custom developed applications for your portal. There is also quite a good portal API for the iPlanet portal server that will allow you to tap into the Logging,Session,Profile and Authentication services provided by the portal.
Hope this helps!

Gaussian Peak Fit and Nonlinear Curve Fit on small data differ from Origin Peak fit

Hi all,
I am developing a program in which I have to fit Gaussian curve on only 4 or 5 data points. When I am using Gaussian Peak Fit or Nonlinear Curve fit, it linearly connects all the points while other fitting software like Origin is fitting Gaussian curve on the same set of data I have attached two images One is from Labview with Gaussian Peak Fit and NonLinear Fit and other is from Origin.
Data is
X                       Y
799.09857      257
912.25256      641
1026.00366   1516
1137.92871   1118
1253.43713   329

Solved!

Labview_fit.PNG ‏15 KB

That looks like a plot of the input data.
When I run it with your data I get a Gaussian curve which looks much like your Origin plot.
The Plot 2 curve is from 128 points equally spaced along X and Y calculated from the Gaussian formula in the LV help using the output parameters from the fit. Plot 1 is the Best Gaussian Fit output from the fit VI. It only has five points.
I used default values for everything except X and Y.

Question about using blending modes when cloning

Hi I want to clone on a blank layer above the background layer. I have the tool set to curent and below and the blank layer is set to normal blending mode. I want the cloning to be in darken blending mode. I change the blending mode of the clone stamp tool to darken. Will that work on a blank layer that is set to normal or is it necessary to also change the blending mode for the blank layer to darken as well? Thanks for your help.

Well thanks. It's not just a portion of the image that I want to clone on using different blend modes, but the entire image. I didn't want to duplicate the background to clone on as it adds a lot in size to the image and its harder to edit out incase I make a mistake. Guess I will have to have two layers, one set to lighten and one to darken. I wish that Adobe would make photoshop work in the next version so that you could just change the blending mode of the clone stamp tool in the tool bar. Wasn't it like this in versions before CS5?
So I have another question for you. Can I use the healing brush on lighten and darken blending modes on a blank layer set to normal with sample current and below selected? Or do I have to switch between two separate layers, one set to lighten, one set to darken?
Thanks again.

Scroll Blending Modes?

Is there any way to quickly change blending modes in CS3 without using the mouse? I'm envisioning a single click in the blending mode drop-down menu and then using the up and arrow keys to scroll through the list.
It's the kind of interface feature I've come to take for granted. Makes for much better speed and ergonomics than all that mousing and clicking, no?
BG

In the Keyboard Shortcut section you can assign single key shortcuts to the Next and Previous Blending mode command.

Blending modes: PSE vs PS

A subject I don't know well is blending modes. I saw an interesting book about this, but it was written about Photo Shop. Is there a difference in the blending modes between PSE10 and PS? TIA

If you ever get far enough into blend modes that you do want subtract and divide blend modes in photoshop elements:
divide:
Invert the layer (Crtl+I) (mac Cmd+I) or (Filter>Adjustments>Invert) and then change the layer blend mode to Color Dodge.
subtract:
change the blend mode of the layer to linear burn and then invert the layer (Crtl+I) (mac Cmd+I) or (Filter>Adjustments>Invert)

Stencil Alpha Blend mode question

Hello guys,
I would like to achieve this: video clip embeded on BLOCKS LEFT DOWN REPLICATOR with another video as a background. So I first apply Replicator, than place the "embeded" video clip into the layer below it. Then I select Replicator to make it active, go to it's properties in Inspector and apply Blend Mode-Stencil Alpha. Up to this point everything works fine. Video plays embeded beautifully on blocks as I want. So I place my background video into another layer below. Here is where the problem starts. My background can't be seen, because it's covered by black areas between blocks. Could you please tell me what I do wrong? How can I make that black area between blocks transparent so anything behind the blocks could be seen?
Thank you so much for any tip or advise,
Cheers,
K.

Don't use Stencil.
Click on your foreground video. Type ⌘-Shift-M to add a mask layer. Drag your blocks replicator into the mask well.
post back,
Patrick

Blend mode in Particle Generator

A blend mode i set for a particle generator seems to effect the partiles as a whole, but not individualy. I am using Darken for example. The particles darken the background, but not each other. Is there a way to make them darken each other?

Blend modes do not work between particles...with the excpetion of the "Additive Blend" option provided in the particle cell inspector... that's unfortunate.
You can achieve good "separation" by applying a drop shadow to the Particle Source.
You cannot get a true Darken effect, but I'm going to outline a cheat to get some interesting effects (this assumes your particle source is a shape, white in color -- colorization is controlled by the Particle Cell color controls.)
[For a quasi-darken effect, use Color Over Live, with a darker color on the left grading to a lighter color to the right. You will want to start with Additive Blend turned off -- you can turn it on afterwards to see if you like the effect.]
With the Particle source selected, in Properties, turn on the Drop Shadow (you will want to experiment with the color -- depending on the mode you choose.) Soft Light, Color Burn, Color Dodge, Hard Light, Hard Mix (sometimes) and possibly the Stencil/Silhouette group will create some interesting different effects. [Remember to experiment with drop shadow color.]
You can adjust transparency with the Particle source (Properties) Blending Transparency, the Fill Opacity (shape tab) or use the Opacity control in the Particle Cell color control.
Since we're cheating here, watch out for a specific effect "sticking" (usually you can snap out of it by sliding one of the gradient sliders in the particle cell color control.)
These settings created a sort of lozenge looking shape -- color gradient on cell is a medium dark orange to a medium light orange. Drop Shadow is a green and the blend mode set to Soft Light.
Below (same frame as above) is a white drop shadow with Silhouette Alpha blend mode...
HTH
happy hunting!

Why no lighten/darken blending modes in Lab?

With PS CS, I have noticed in Lab color space the lighten and darken blending modes for layers are disable. Also, if an RGB picture uses them, they are converted to normal blending mode upon conversion to Lab. Any idea why this limitation? And any way to circumvent it?

This is true also for the Color Dodge, Color Burn, Difference, and Exclusion blend modes in CS3. (I don't remember if all of these modes exist in CS.) The only way to circumvent the mode conversion when switching from RGB to LAB seems to be flattening beforehand---not likely to be a happy solution for you.

Blending mode in PE 13

I have Premiere Elements 13 and understand it supports blending modes (like Photoshop Elements)... but can't find anything in menus, etc. to get me started. How do I access this feature? I've searched every menu, pull-down, etc. and find nothing. I want to use "multiply" to try to darken a very bright scene. Thanks.
GORDON

GORDON
What computer operating system is your Premiere Elements 13 running on? Have you updated to the 13.1 Update from within an opened project? If not, please do so.
As for your question as to where these blend modes are in Premiere Elements 13 Expert workspace..see Applied Effects Tab/Applied Effects Palette/Opacity Panel expanded
Duplicate your video clip. Stack Video 1 video original Video 2 duplicate, highlight the Video 2 duplicate, then Applied Efffects Tab/Applied Effects Palette/Opacity Panel expanded and the Blend Mode options.

The math behind blending modes

Anyone know of a handy dandy chart showing the actual math behind the blending modes? (Trying to find or build equivalents in Nuke)
Specifically I'm looking for Classic Color Dodge and Hard Light.

I guess when you mention classic this is what your referring to?
