Photoshop tips for 3D production_Part 2

                                             
                                       

Optimising 2d file sizes using the “Save for Web & Devices…” tool

When sending drafts or pre-finalised images to clients for comments and/or signing off, most users tend to use the “Save as…” tool, or/and resize the image/s.

With pre-finalised images, the above mentioned approach may prevent clients from making the right judgment about the image/s and subsequently NOT signing off the image/s as quickly as anticipated.

When using the above mentioned approach (i.e. Save as, etc.), clients often comment on the pixel quality and the image size.

In addition, it may prove to be, a bit of a challenge to send multiple files via email.
To address all of the above issues (when sending pre-finalised images), some companies tend to use the “Save for Web & Devices…” tool, instead.

1-To do so, in Photoshop, click on the “File” main toolbar, and choose the “Save for Web & Devices…” tool from its drop down list. 





2-If the pre-finalised image is exceedingly big in pixel dimensions (i.e. in this example it was 7360x4912), you’ll be prompted with a “Save for Web” warning dialog related to memory errors and slow performance.

Accept it by clicking “Yes” to open it.  





3-With the “Save for Web & Devices” dialog open, Photoshop automatically chooses the “Optimized” tab with its “ideal” “optimized” values (i.e. Quality=60), without compromising the quality of the original image. 

This useful dialog offers users the option to compare between the “Original” tab, and the “Optimized” tab parameters.

On each tab, the user can see and compare the quality between, the file sizes (i.e. at the bottom); set the “Image Size”, etc.
Always pan (using the pan tool) to areas of the image that are more prone to scrutiny by the client. 
In this example, we have focused mainly on the rendered areas of the main building.   

Furthermore, the “Preset” quality was changed to 30 and left the “Image Size” parameters untouched.

As one can see between the “Optimized” and the “Original” tab below, the image went from 103 MB, to 3.692 MB in size, without affecting the overall quality of the image or its dimensions.

Once satisfied with the final optimization, simply click “Save” and choose the location to save the file in. 





It’s worth mentioning that, one can also use Photoshop actions to automate this process for the subsequent images.
For more information about Photoshop actions, please check the previous post:



4-Alternatively, users can also use the “Batch” tool to automate actions.
To do so, simply click on the “File” main toolbar, followed by choosing to “Automate” and “Batch” from the drop down list.




The “Batch” dialog box is broken down into five groups: Play, Source, Destination, File Naming and Errors. 



Play: This group allows users to pick and choose pre-created action parameters such as Set and Action.

Source: This group allows users to locate the folder where all the files will be sourced or collected from.

To choose the folder, simply click on the “Source” toggle.

The source folder comes with four functions:

Override Action “Open” Commands

Include All Subfolders

Suppress File Open Options Dialogs

Suppress Color Profile Warnings

Alternatively, users can simply click on the “Source” drop down list and choose the “Opened Files” option.

The “Opened Files” option automatically sources the open files in Photoshop.


Destination: This group allows users to determine the location of the Saved file/s. 

Users can choose from the following options:

None

Save and Close

Folder

The "Folder" option allows users to choose the file destination and to Override Action “Save As” Commands.

File Naming: This group allows users to add numerous variables from the drop down list of the name field.

The most commonly used variables from the drop down list are:

Document Name

NONE

EXTENSION

The variable under the name of “EXTENSION” in fact adds the file extension name in front of its name (I.e. name.GIF).   

The “Starting serial#” function, automatically adds a serial number/s to the file name. 
To omit file numbering, simply keep this field clear, by simply “deleting” the number/s in this section.  

Errors: This group allows users to either “Stop for Errors” (if any) during the file batching process, or to simply “Log Errors To File” (if any).

I hope you have found this article somehow useful.
