Effective ppi in photoshop

Hi ,
im using psp cs2.
when placing images in the composition its easy to get lost and to have your images in a low resolution due to transformation. is there a way to see the effective ppi of a layer content? by effective ppi i mean the resolution of an image in perspective to its size.
Thanks
S

Once in the target image the placed item will have the resolution of that image.
The secret is to check the resolution of the item before adding it to the image.
If they are not the same, the item will appear to shrink or expand as it adopts the resolution of the target image

Original and effective ppi

Hey everyone! I would like to ask for some urgent help on Indesign + PDF print document subject.
I prepared a document for offset print (business cards 8,5cm width x 5,5cm height) and it turned out that the pictures were very rastered on the Proof. Like, you could see the raster dots on it.
I checked out my Indesign document again and I found out that the original ppi of the images was 762 and the effective ppi over 1000. I then realised that on Photoshop, I setted by mistake the pictures´s resolution for 300 pixel per cm instead of pixel per inchs!!
I changed that and they have now:
300 pixel per inch resolution
4cm width x 5cm height
and the pixel dimensions are: 472 px width x 591 pixel (height).
In the Indesign document, it appears now:
300 original ppi
between 300 and 400 effective ppi
472 px x 591 px dimensions
My question is, do you guys think I solved the problem that way or should I still change something before I sent it again to print?
The real dimensions of the pictures on the business card should be about 4cm width x 5cm height, so I decided to have them on Photoshop with that dimensions and 300 pixel per inch resolution, so that I don´t have to scale them much on Indesign. Did I do it right?
Thank you!

The original psd file has, more precisely:
Image size: 14,8 cm width x 21 cm height
Resolution: 762 px / inch ( = 300px/cm )
Pixel dimensions: 4440 x 6300
Then, I changed the Resolution from 762 px / inch to 300 px / inch, and checked in the "resample image" option, which converted the Pixel dimensions into: 1748 x 1418
(Image size remained the same)
This file has good detail quality, it looks sharp.
Then, I drag the layer from this file to a new one, with the image size I need :
Image size: 4cm x 5cm
Resolution: 300 px / inch
Pixel dimensions: 472 x 591
Which makes me think of another question: Are these Pixel dimensions enough for print? Is this psd file good enough to place in Indesign and for print?

Actual vs Effective PPI

I see in the info when I click on a specific link in the links panel two items I don't know how to tell them apart. Can anyone give me a good explanation of the difference between actual and effective ppi. Which one is important and which one you really need to pay attention to and why. I understand that a picture needs to be at least 240 ppi for print. I've read several articles and just don't really understand.

Actual resolution is the resolution as you would view it in an image editor like Photoshop.
Effective resolution is the scaled resolution. If you scale the picture smaller in InDesign, you're "squishing" the pixels into a smaller area, increasing the effective resolution. If you scale the picture larger in InDesign, you're spreading the pixels over a larger area, decreasing the effective resolution.

Can "Actual PPI" and "Effective PPI" be extracted from InDesign?

A script that I may require, needs to reach inside InDesign and extract the Actual PPI and Effective PPI from certain images, and then process the images in Photoshop. Are those variables available to scripts?

Update: this applies for javascript, i don't actually know if you in Applescript would use the Open Library function, and then selecting Indesign.?
With Creative Suite comes a program called Adobe ExtendScript Toolkit (in CS3 and CS4 its ESTK 2).
Open this program and look under (for CS3) "Help" -> "Adobe Indesign CS3 Object Model" this is the Object Model Viewer, or in short OMV.
In there you will se all the available objects, methods and so on.
If f.ex. you will like to know how to get a reference of a image:
app.activeDocument.pages[0].images[0]; // will give you the first image of page 1 of the currently active document
In ESTK, click application, now you see all available objects for the app (activeDocument is one of them), click this and you will see that Data-Type is document. Click on the blue link document, now you see what objects are available for a document.
Have fun.

Effective PPI in .eps files

Anyone know how to extract the effective ppi info in .eps files? Photoshop.eps and Illustrator.eps files are different, so whichever you may have info on would be appreciated. I believe Illustrator generated ones are read as .pdf docs, so it may be impossible.
Thanks,
Seth

Why not use the built-in preflight for this? It will get the effective ppi of Illustrator and Photoshop eps's.
Uh-oh. Egg on face and all of that.
I didn't get to see the effective ppi, but if I place this EPS image into InDesign
I get a preflight message 'something is wrong'. If I make the image smaller (and thus increase the ppi), the error disappears.

How can I use multiple overlay effects simultaneously in Photoshop?

There are 3 overlay effects available in Photoshop as layer styles: Color, Gradient and Pattern. The problem: these effects come in a strictly fixed order!
Is it possible to make a translucent Gradient Overlay over a Color Overlay using only layer styles? Or a Multiply Pattern and Color Overlays?

Another option would be Grouping the Layer, applying one Style to the Group, grouping that Group, applying the next Style to that Group, etc.

How can I create an iridescent effect in a Photoshop 3D object?

How can I create an iridescent effect in a Photoshop 3D object? I have searched everywhere for downloadable option for a mac with no luck. I'm working with CS6.

NO way. Such stuff isn't even commonly available in many 3D programs becaus it's actually pretty advanced shader stuff...

I have an issue using Lighting Effects in Adobe Photoshop CC 2014

Hello everyone,
I am having issues using Lighting Effects in Adobe Photoshop CC 2014. I created a duplicate layer that I want to do the effects on, converted it to a smart object and on that same layer went to Filter>Render>Lighting Effects to get to the Lighting Effects screen. When adjusting the parameters (drag/reshape the lights) for either the spotlight or point light, I don't see any changes. Can someone tell me what could be the issue or if I'm doing the steps wrong to apply the effects?
Here are my specs:
Operating System: Windows 7 Home Premium 64-bit (6.1, Build 7601) Service Pack 1 (7601.win7sp1_gdr.140303-2144)
Processor: Intel(R) Core(TM) i7-2600S CPU @ 2.80GHz (8 CPUs), ~2.8GHz
Memory: 8192MB RAM
Available OS Memory: 8174MB RAM
Card name: AMD Radeon HD 6570
Manufacturer: ATI Technologies Inc.
Display Memory: 743 MB
Dedicated Memory: 1008 MB
Shared Memory: 3831 MB

I am experiencing flickering issues as well. However my issues are with the Fast Color Corrector and the Three Way Color Corrector. It seems as if the color correction tools are causing intermittent flickering on some people's systems.
Additionally when I converted some old PPCC 7.2.2 projects which had the Three Way Color Corrector applied, some clips in sequences would come up as a green screen in the program monitor. If I turned the TWCC off the footage would display correctly in the program window. If I turn the TWCC back on it would display the green screen again.
I haven't found a solution to the flickering but to solve the green screen issue I have to remove the effect, then re apply it. I guess for whatever reason, the 2014 version of PP has issues with 7.2.2 projects where the TWCC was applied.
I'm hoping Adobe will address this soon with an update for the various bugs that have been reported.

Why effective PPI format change?

Hello there!
The effective ppi format change to "effective resolution", like 2356x1678px. I want back to real ppi, like 370ppi. How do i get back?

Since I notice in your screen shot that you have two different images with non-proportional scaling, I might point out that you can use InDesign's Preflight panel to search for such images. In the IMAGES and OBJECTS section of the Preflight Profiles dialog box, check "Non-Proportional Scaling of Placed Object" in your preflight profile.

Effective ppi, where did you go?

Help! Since I upgraded from CS2 all the way to CS5 I'm having trouble finding some of my favourite features. I've spent a lot of time looking for the effective ppi information in the info tab.
The new info tab shows no resolution at all for eps-images. How can I figure out the effective ppi after I scale the images now???

You could trigger live preflight for showing the effictive resolution of all images (EPS included!) if you use a very low threshold at max. resolution and even more lower value at min. resolution.
Downside:
it will slow down your operations tremendously and you have to single out your selected image you want to check…
Note 1: first edit the minimum resolution, then the maximum resolution field of your new preflight profile.
Note 2: don't try to set your minimum resolution values higher than your maximum resolution. Might crash your InDesign. In my case it was InDesign CS5.5 (7.5.2) that showed an alert window with an appropriate message and an ok button that I could not cancel even if I hit ok several times. I switched back to my browser to edit this message here and InDesign crashed in the background; (sometimes I try silly things just out of fun ).

Effective ppi

Hello All,
My friend and I are working on an art book project being printed on a satin/matt 100lb artpaper. All images are full bleed 9.75 x 12.5. Our effective ppi's are ranging from 280 to 400. We were going to downssample them to 300 dpi on export in order to give the printer a document with all the same ppi. Do I need to upsize the ones that are 285? Can that be done in InDesign? I have originals on some of them that are larger if need be. Would you see the difference? Is there a reason to give a pdf to a printer with a consistant ppi? Would they change their lpi within a single job or just print it all at the lower one?
Thanks!

Thanks Bob,
I think it is a pretty high end press. They do a lot of art books. Will they reduce the overall lpi for the book because of those few images that aren't 300 ppi? Or would they still use 150lpi or 200lpi on the whole thing? Or would they adjust the lpi for each image?

Bridge opening all .jpg in after effects rather than photoshop

I briefly used after effects earlier today and now bridge is opening all .jpg in after effects rather than photoshop. Photoshop is set as the defult and I've tried resetting preferences etc but it continues to open in after effects having to right click and opening with on every image! How can I change this back to using photoshop?

The folder view is as normal but as you can see below at the very top of bridge rather then just having the directory name it now says "Opening in Adobe After Effects..

That looks like you copied some obsolete versions of those plugins into the CS4 plugins folder.
That or you ran a utility that stripped part of the binary data (PPC or x86) from the plugins.
