Smart object stack modes - in english please

How do we make sense of these stacking modes?
I tried the median technique to lose the disparate elements, nothing.
Those others, how do we interpret the definitions for real world use?
Thanks anyone.

I tried but this is what I got:
"There is no Adobe PDF viewer installed to view the selected file."
So far, this is the most definitive item I have found,
hence my questions:

Show movement in area from 30m video, smart objects - stack mode - range - 90k frames

Hey,
So I have a real challenge and need help figuring out the logistics of how to get it to work sensibly.
I'm trying to visually show the movement through a space (which will later be generated into a 3d form etc..)
To do this I think the best way would be to use photoshops smart objects - Stack modes - "Range"
A final image to show movement through the area.
Lighter where people walk more often and darker where people walk less often
http://help.adobe.com/en_US/Photosho...44D6937Ca.html
Range basically shows everything that has moved between the layers.
If you import a video frames into layers in photoshop, make them a smart object and apply the range stack mode it shows peoples movement and where they walk.
So thats what I'm going to do unless there is a better way to do this in something like after effects or premiere pro that I don't know about?
- I've done the photoshop way before and it worked very well - but on a very small scale.
I have a 30 minute video recording (considering longer but not sure if its viable), it was shot on a tripod and seems ok but can always do it again differently if needed!
The video was shot at 1920 x 1080 50fps which with 30 minutes (1800 seconds) makes 90,000 frames total for the video.
The problem
I need the info from ALL the frames - any less and the movement is too 'choppy' and isn't very useful.
So how can I make use of 90,000 frames/layers in a smart object for the range stack mode?!
I heard photoshop has a layer limit of 8k.
I have access to 6 high spec brand new mac pros (not 100% sure of the spec).
I'm thinking the solution would be use scripts and break it down into manageable chunks then flatten then merge them together.
Possible Solutions
1. Merging frames from each second or few seconds and then blending - not sure what blend mode I would use and also not sure if it would affect results
2. chop the image down into sections, process each section, flatten and merge together. for example split it into 4 quarters. - Don't think this will help, its more the limits in layers than anything else
3. Find an alternative method to deliver the image such as after effects.
on a side note I know I could have done a long exposure, done many before, but they don't really show movement, they simply blend the frames. The downside of long exposures for this exercise is that things could cancel each other out, for example; a man with a white top on walks past then a man with a black top walks past, these would cancel each other out to some degree.
The Range smart stack mode is brilliant because it directly shows movement and people don't cancel others out.
Help
Where can you help?
So basically if this is the correct way to do this then can anyone help with this and suggest any ways of breaking it down that wouldn't affect the final result?
Someone that knows more of how range stack mode works.
Correct me if I'm wrong with any of this and please let me know if you can help at all
Thanks!
Luke.
Context
For context the final thing has to be something that doesn't change in time, i.e. not a video but an image or model. This image will then be skewed a bit so its a plan view. It will then be used for another script in a 3d package like rhino which will create a number of points in space, the x and y axis being the location in plan view and the Z axis being the value of the pixel. I will then generate a solid form from the points and then smooth it out a lot so I should end up with a 3d wave model directly generated from the movement of people through the site. I will then architecturally design the form into spaces etc... This will form the surface of my final project
Heres an example of the first 500 frames (500 frames limit on video frames to layers import)
The footage isnt the best as I moved the camera slightly and the angle isnt amazing - ideally I want a plan view but will skew the final image to do this.

But I have a concern that if I break it down to 300 images (6 seconds of footage) then stack then flatten the stack until its dont the whole 30 mins then use these flattened ones to create a new stack it would affect results as it will then be working with images like the above.
That should be easy enough to test (if maybe not exactly proof) – for Range it seems to make no difference, for Variance it seems to do.
Also why use 16 bit image mode?
To reduce the accumulated effect of the necessary rounding of pixel values.

Layers Smart Objects Stack Modes (CS3/4 Extended)

Are any of the Stack Modes besides Median and Mean (Noise reduction) good for anything? Have any of you found a use for them?
Thanks!

If you don't recognize the statistical names on them - then they probably won't be of much use to you.
If you are doing statistical work on images, then you should recognize the names and they would be quite useful.

Stack mode in Photoshop CS4

Hi all,
I'm trying to use the options 'layers - smart objects - stack mode'. However 'stack mode' is greyed out. I've read on a few forum posts that this functionality is only available with CS4 extended.
Can anyone tell me if that's correct. And if so is there an upgrade route to allow me to get the extended version?
Thanks
Darryl

You're welcome. If you choose to get CS6 you won't need to buy Lr again. If you do get Ps CC you will get Lr for free and free upgrades (Lr 5.7 and Ps CC 2014 15.0 currently).

Blend Mode doesn't hold in Smart Object

Here's the scenario:
I'm building a web page, lot's of layers and groups. I want to clean things up by converting some groups into smart objects.
Here's the Problem:
Within some of the group folders are layers with a blend mode assigned, like Darken. When I convert the group to a Smart Object the blend mode on those layers doesn't hold.
Screen grabs:
Hopefully these will make it clear in cas I haven't explained it well.
Original with layers
Group converted to Smart Object
Bland mode applied to Smart Object
I figured out why it happens, I want to know if there's a way around it other then don't do it.
TIA,
Mike

Yep, another understandable feature by few who understand, but created by many users - toy feature for web and print. It can either mean money or murder when handed these files from your bone head customer who assumes anything that can be created shall work with the greatest of ease because marketing told you so.
Now that's progress intelligently planned.

CS3 - Bridge Smart Object image to CS3 & Lab Color

I open an (NEF) image in Bridge, do some work, and open the smart object in CS3. When I go to Lab Color I get: “Changing modes can affect the appearance of smart objects. Rasterize smart object before mode change?” I don’t want this, correct?
After I choose “Don’t Rasterize” this dialog window appears: “Merge layers before mode change?” I choose no.
Within Channels (Lab Color) I go to delete “A” & “B” because I just want the Alpha Channel. However, I get “Flatten Layer?” and when I choose “No” I can’t delete “A” & “B.”
Solution?
~ Much Thanks ~

I should say I am trying to learn this software and stumbling through Mr. Kelby's 7 Point System book.
I found my error. I was highllighting the layers not clicking the eye icons off and on.
Thanks for all who look.

Add canvas to a cropped smart object

Hello,
Using PS6 64 bit.
I bring in an image as a smart object, crop it (with 'delete cropped pixels' checked) and then attempt to add canvas on all sides.
The image reverts to its pre-cropped size with the added canvas on 3 sides.
If I flatten the smart object before adding canvas, it works fine.
Is there any way to get this to work with a smart object?
Thanks.

Could you please post a screenshot with the pertinent Panels visible?
In the clipped state you could add a Vector Mask (Select All, Make Work Path) to the SO.

Photoshop CC 2014 - Stack Mode Disabled - Load Image Into Stack Has No "Convert To Smart Object" Option

Hi,
I have just installed Photoshop CC 2014.1 and I have "Stack Mode" command disabled.
Also, I have no option to convert layers into smart object when I run "Load Image Into Stack" command.
Can you please tell me how to enable these features?
Thank you very much.
Luca

The 512 MB are a minimum requirement, not some optional thing. Without it, 3D will never work.

Smart Object and blend mode issue

I have an object that I moved from another image and needed to resize. The object is an image of a bottle and glass, with both the bottle and glass having reflections from their base. They both also have some layer masks with the reflections. I grouped the glass and bottle and created a smat object before the move to the new file). Anyway everything worked fine, except the reflections are much stonger in the new file (they are sitting over the same colored backgrond as in the original. If I open up the smart object and put a background behind the images and the reflections (background is transparent)everthing looks as they should. The reflections have a blend mode of multiply).
So why does the smart object not render the reflections properly (without lowering the opacity more within the smart object group) they appear almost at 100% in the new file. Any suggestions?
Can't post the files as this happened at work.
Thanks
Jeff

Anything to do with soft proofing? Does the new document have the same colour space as the original?

Smart Object Effects Not Shown in 'Play Slide' But Shown in Other 'Play' Modes?

Hi,
In Captivate 7, effects which I add to smart objects using 'Add Effect' in the Effects tab do not show when I 'Play Slide' but do show in any other 'Play' mode e.g. 'Play Project'. Any thoughts would be very much appreciated.
Thanks
Richard

F3 Play Slide is only going to show you what you can see in Edit mode. It only moves the frame cursor across the timeline but does not publish the project to an output.
You can see a Live Preview of the effect applied to a given object by opening the Effects tab (Window > Effect), selecting the object on the slide, and then clicking Live Preview button.
But the best way to see how everything works is to either hit Cntrl + ENTER to publish and preview the project, or else hit F10 to publish to browser.

Script to load multiple linked smart objects to stack

Hi
we have a workflow where we work with exr images, and load about 15 of them at a time into a stack, then from there convert them into smart objects.
As the linked smart objects is out this means we can replace a folder full of images and update them which would save opening up the psd and having to replace conent on all smart objects.
but can't seem to find a way to load multiple smart linked objects in with out having to do 1 by 1.
Is there a simple script to do this?
Thanks

I had asked Adobe about a modified script to do this, but at this time, they didn't seem interested in developing it. Perhaps if more people ask for it they would add this feature, which would be extremely handy. Don't know if anyone has come up with their own script for this yet, but I'm sure someone will.

Stack mode and rating images-WORKFLOW SUGGESTIONS PLEASE

I have a couple of issues when working in stack mode.
The first is that although I can rate the image that is bordered in white I don't see an easy way to rate the image with the yellow border?
The second thing that gives me fits is how when I am in stack mode the up and down arrow keys skip over unstacked images while editing.
My workflow now is to take two passes through a set of images. The first in stack mode to get the stack picks and alternates set. The second pass which I do in Primary mode is to rate the images. This has the disadvantage of not rating the stacked images which are not the 'pick'.
Anyone got some suggestions from their own workflows?

Sailor,
The problem with the opt + return item is that it kicks you out of 'Stack view' into 'Primary' and if you want to return to 'Stack view' then you have to do 'opt + t' and you have lost your place in the stack. (i.e. in a stack of 7 if you were looking at items 1 and 4 when you return to 'Stack view' you are back to looking at 1 and 2 again)
CONFUSION POINTS: I was using the keyboard shorcut card that came in my v1.0 Aperture box, some of those shortcuts are no longer correct. I have also found that not all of the shortcuts on the current PDF Quick Reference are working as expected.
I recalled that you can use 'opt =' or 'opt -" to increse the rating on the yellow bordered item. This might lead you to expect that opt 1-5 would assign ratings to the yellow border image but those shortcuts assign metadata.
I think a part of my problem is that I have been working with much too large stacks. Stacks work better for me if they are smaller and contain images that are visually equivalent but differ in minor details that need magnification to resolve.

Retaining local axis in Transform Mode (non-Smart object)

Hi guys,
I was wondering if there is any way to track an object's rotation axis something like the difference between Local & Global axes in 3d programs.
I know if I started the transformation as a Smart Objects and keep it as a smart object, it does remember. Is there any other workaround for a non-smart object to retain this information?
Just trying my luck here. Thanks

There is a big difference between a smart object layer and a raster later. Though a smart object layer seems to behave like a raster layer its operation is very different. The Pixels rendered by Photo do not change they are only acted on. Everything is recorded for the layer each smart object layer has an associated transform. If you transform the layer again you actually adjusting the recorded transform your not making a new one. If you transform a raster layer you wind of with a different layer, Pixels may have been deleted or added you do not have access to the old data except in Photoshop history states till it get deleted. Smart object data is protected and survive even save in a layered document.

What is benefit for make a SMART OBJECT

Dear all,
What is the benefit for make a smart object in photoshop
Manoj

Have you even bothered consulting the Help?
Anyway, the advantages of Smart Objects are numerous:
• multiple instances of a SO in a containing document that update simultaneously on saving an edited SO (please note that a SO once placed has no connection to the external file but resides inside the containing document)
• the possibility of placing vector content as Vector Smart Objects (though this will output as pixels)
• non-destructive application of Filters
• non-destructive application of transformation, warp, puppet warp (not all of these are available for Vector SO, but by converting such a one to a regular SO they become applicable)
• combination of elements of different color spaces
• the ability to Replace Contents of SO (for example when faking as-of-yet non-existent products by mapping packaging design elements onto images of a blank container and the design is likely to change)
• Stack Modes for certain combinations of photographic images

Linked Smart Object: Allowed File Type and Editor

Please forgive my lack of knowledge. I'm evaluating PS CC 2014, own PS 5.1 and am a hair shy of being a novice. Presently I'm doing Photomerge Focus Stacking. What I'm hoping is that DNG files can be Linked Smart Objects and that I can modify the merged photo by editing the DNG files in Adobe Camera Raw. Is this possible? The Adobe Help article has a rather cryptic "You can’t perform operations that alter pixel data", that leads me to believe no but, I don't understand that fully.
Thanks.

Currently you can not use any of the merge options: pano, hdr, or focus stacking with a smart object. So you would not be able to do that with dng files and retain the ability to edit them in Camera Raw. It would be nice though!
