Aperture 2 Export DPI Settings

I've wrote on this subject before, and I have re-read all the responses. I have yet to have a clear understanding of the "DPI" setting in the export dialog, and the default setting of 72 DPI. I am quite familiar with DPI, PPI, pixel count and dimensions, and resolution as it is determined by print size and pixel ratio. I'm still not clear on why Apple has this box here, and why they call it DPI.
I know DPI and PPI can and will be interchanged and being aware of context in this area is important. But what purpose does this DPI box serve? What is it doing in the export dialog box, and how does it effect you by changing the 72 DPI to lets say.....260 DPI?
Does anyone have a clear answer on this? I've been searching the entire manual and can't find anything that details this little box, its function, or reason it is there.

All the DPI setting does is tell the software that you open the file up in how to display rulers. It will have no effect on output quality what so ever.
Here is a blog post I wrote on the subject, I hope this helps.

DPI and PPI in Aperture 'Export' and 'Print' windows

Hi,
As mentioned in an earlier post, I just bought an Epson 3880 printer and some Epson Hot Press paper, so now I have to pay attention to PPI (term used for displays) and DPI (term used for printers).
In Aperture however, files being exported require DPI specs(!), while files being printed require that we specify PPI specs. How is that?
Also, my Epson manual indicates that I can print at 5 distinct "DPI" settings, from 180 to 2880. My Aperture Print window, however, only offers 3 options with 360 "PPI" as the highest (considered Draft quality by Epson - if "DPI"), plus a 4th referred to as Custom.
Also, I have a note jotted down a while back that says: "1440 dpi for most papers with 240 dpi files, at 2880 if 360" - whatever that meant 6 months ago at an Epson 3880 seminar, before I got the printer.
Can you guys sort this out for me? Please?
Thanks a lot,
Raphael

I'm not at my studio. My current driver is 8.x. The newest driver is 9.33. My remarks here may not fit with your more current version of the driver (but that would surprise me — the printer came out about 4 years ago, iirc).
The profiles are not, afaik, included with the driver, at least when you download it from Epson's site.
There are two profiles for each Epson Fine Art paper — one at 1440 and one at 2880. You should try each with every kind of print you make, and determine which is better. IME, _for my needs_, 2880 was never worse. I use the 2880 profiles.
The profile is selected from the "Color Profile" drop-down at the top of the "Rendering" section of Aperture's "Print" dialog.
(Set "Render Intent" to "Perceptual" for, in general, photographs or anything with smoothly graduated changes in color. Set "Render Intent" to "Relative Colorimetric" for, in general, graphics or anything with smooth areas of constant color and sharp transitions between areas of color. Generally, if "Render Intent" is "Perceptual", check "Black Point Compensation"; otherwise uncheck it.)
Leave "Print Resolution" at "Auto". I know of no reason to ever change this. (I don't, in fact, know what this control does, and have never changed it.)
When you click "Print" in Aperture's "Print" dialog, a short dialog opens asking you if you want to save any changes you made to your Preset. I always save my changes. Prints often need to be immediately remade — all transitions of data from electronic to physical media are problematic — and I like to return to my Preset ready to print the same Image(s) again.
When that dialog closes, the OS print dialog opens. Your 3880 printer should already be selected in the "Printer" drop-down. You need to create and should save an OS Preset for your paper. Note that on the "Color Matching" page (this dialog has pages, not tabs; direct complaints to Cupertino), all (two) options should be grayed-out. This indicates that Aperture is handling color matching, which is what you want (for best prints and anything approaching a color-calibrated workflow). On the "Paper Handling" page, the "Destination Paper Size" drop-down is grayed-out, but should show you the selection you made in the Aperture Print dialog. The "Printer Settings" page has two tabs. On the "Basic" tab, in the "Media Type" drop-down, select your paper ("Fine Art Paper ▹ Hot Press [Bright or Natural])*. The "Ink" drop-down should be grayed-out, but show "Matte". Matte is proper selection for Hot Press [Bright or Natural]. This dialog knows this from your color profile selection in the Aperture Print dialog. Chose "16-bit" output and any other options your want (you can experiment; I find no difference). I ignore the warning about print quality at the bottom area — this has never been an issue. On the "Advanced" tab of the "Printer Settings" page, it should tell you that "Epson Driver Color Management is Off". That's what you want. You want Aperture to manage the color.
Save your OS print dialog Preset. Use it every time you print to the same paper.
*If you cannot select your paper, you have not selected the correct paper size in the "Printer" section of Aperture's Print dialog. Note that the "Paper Size" selection includes not only the paper size, but also whether the feed is by sheet-feeder or manual, and whether or not the print is borderless. (I didn't design this; I assume there are reasons to have shoe-horned these options into the "Paper Size" selection.
This is all tricky on top of being actually complex and next to being new. It takes everyone time and mistakes (read: ink and paper) to canalize a flow that works for producing the prints they want. I hope this gets you there a little faster. Report back with what doesn't work.

Recommended DPI settings

Looking for some advice on DPI settings when exporting Nikon D200 RAW images to print photos, books, converting from RAW to JPEG etc.
At what point does it make no difference except file size?
Thanks.

DPI is used only to determine how large to print an image. In other words, if you have an image that's 3000 pixels wide and you set it to print at 300 dots per inch, it will print at 10 inches wide. If you have an image that's only 300 pixels wide and you print it at 300 dpi, it would only be 1 inch wide.
That is the only use of DPI. DPI does not determine an image's digital resolution. The number of pixels determines the image's resolution.
Generally speaking, if you're printing an image on paper you're better off with the largest image you can get.
At what point does it make no difference except file
size?
When you are exporting an image to be used in a digital presentation, such as on a web page or on TV, that's when you don't need to worry about DPI. That's when what only matters is the number of pixels in the image.
For example, if you export that image that's 300 pixels wide to display on a computer screen that's 1280 pixels wide, the image will take up about a quarter of the screen. And it doesn't matter at all what DPI setting you might have set.
You can download a PDF file of a chapter from one of my old Photoshop books that explains digital imaging resolution at http://www.seekpeace.com/viz/res/Resolution.pdf.

Is there a way to export workspace settings?

The problem is, I work with a two-monitor setup. One is the actual working area with a painstakingly constructed layout of panels, the other one has a synchronized window with a full-screen Preview. Every once in a while I accidentally close the working area window, and because Bridge only saves a "current state" in workspaces, my painstakingly crafted window is just gone, poof (sound effect, not slang).
I know I can save a duplicate working space. That makes it somewhat easier, but I still have to delete the botched working space and create it again as a copy of the duplicate. This, coupled with the fact that the first stage of any troubleshooting on Bridge is to nuke all settings, makes me a bit uneasy with the solution.
I would be very grateful if someone knew of a way to export workspace settings so I could just load them back in when I mess up or Bridge does.

Would you mind disclosing the resolution of your 30" monitor in terms of pixels (so many pixels wide by so many pixels high) ? I'm just curious to see how such a large monitor compares to my two side-by-side 22" monitors.
Hallo mr de Gokker!
Nice to see you also here
The resolution I use with my 30 " is the default one and set to 2560 x 1600 pixels
If I can take a little 'gamble' I assume the total pixel amount of 2 x 22" will be more, but I never could get used on the two monitor set up. I just like my tools to be close to the image I work on, and using the pen tool with a lot of Brushing and switching to different layers and combine this with action pallet in button mode that needs also a lot of pressing it would be to often en to much distance to travel for my hand, but that's just personal.

Aperture export to Photoshop error

Hi all,
This is a bit of a very specialised issue that I noticed - so only an issue for the very high end user. But big enough of a problem that I have to change to Lightroom until this issue is fixed...
Following Problem statement. I get an error in calcutions in advanced Alpha Channel Masking... see attached images to understand the problem
Here is what I do to get the Alpha Mask:
1) From Aperture export Image to Photoshop
2) You want to calculate a certain coloured area to do some very subtle editing - say a skin rash
3) You select Green Channel for highest contrast between rash and skin
4) You go in Calculations and on merged layers in inverted mode you do a multiply calculation into a new selection
5) You get a selection. You want to refine it
6) You do calculations again and this time on the selection layers (not inverted) you do an overlay calculations into a new channel
You see that the Mask has square patches - misaligned information ...
I don't understand what they are because when you look in RGB there is no error.
Also note that this must be related to Aperture - because when I import the .NEF file directly from the camera into Photoshop or via Lightroom I don't get this issue.
(I am using a NIKON D700)
Second more minor but annoying issue - skin colours are way more yellowish than in Lightroom ...
Can anyone fix this or point to how it can be fixed? Should Apple be notified?

I also wanted to add an image of how the masks looks like - i.e. without issues - when you import into Photoshop via Lightroom

Exporting Bridge Settings on Network

Greetings fellow Bridge users, I would like to manage my visual assets through Bridge. I have created several image folders and added keywords to each image, all of which live on a network. I would like to export these settings so that my coworker can also search the same assets (on the network) on their computer, using the same keywords without having to tag them all over again on his computer. Seems like there should be some kind of settings I could export in order to do this. We are talking about 3,000 images so if I have to retag them then I'll have to look into a different solution to manage my library at work. Any help you may have to offer would be greatly appreciated. Thanks!

Bridge is just a file browser, by no means a robust DAM (digital asset manager). Its performance in a network environment is iffy.
Please see this very recent thread here:
Is there a stand alone version of Bridge and whats the cost per license?

Want to export user settings from Office 2007 on client, to be able to import in Office 2013?

Upgrading from Office 2007 to Office 2013. We may need to save the user settings on the client computer, because we are moving some of the systems from 32-bit to 64-bit. How can we export the settings to a folder?

Hi,
Could you please tell us what is included in user setting? Such as the customized Quick Access Toolbar settings, customize ribbon settings, or profile in Outlook?
Generally, we can’t upgrade operating system from 32-bit to 64-bit directly, we need to reinstall 64-bit operating system.
Office 2007 don’t provide the Import/Export button like Office 2010/Office 2013, we can’t export QAT setting and customize ribbon setting directly.
To customize an installation of Office 2013, you can use the Office Customization Tool (OCT) to perform tasks such as the following:
Specifying installation options
Customizing how Office applications and features are installed
Configuring default user settings
Managing additional content: add or remove files, registry entries or shortcuts
Configuring Outlook options: setting the default profile, adding email accounts, and specifying Exchange settings
For more detail information:

It's recommended to download and install

Is there a way (or a plugin) to export develop settings into a readable file format?

For online educational/sharing purposes, I'd like to be able to export my LR develop settings into a readable text format so that if I share a before/after picture I can also include the LR develop settings that went into creating the after picture. I've looked for 2 days and I can't find a plug-in that will do this.

The List View plugin can export develop settings as a CSV file for Excel or HTML for a browser.
If you're technically minded and comfortable with scripting, it's straightforward to write a script that reads the settings from the XMP metadata stored in the .xmp sidecars (for raws) or in the XMP metadata section of JPEGs and TIFFs. Open a .xmp sidecar in your favorite text editor to get a flavor of how the develop settings are stored there.

Server 2008 SP2 DPI settings

Does anyone know if there is another hotfix or update planned to address this? We have changed the resolution settings on the client computers, but was curious if anyone had any additional information on whether this may be
addressed or not. Thanks.

How do you change the dpi settings in iPhoto

How do you change the dpi settings in iPhoto

Short answer: the dpi is set when you decide what size you're printing at.
Long Answer: Dpi means nothing in the digital world of your computer. There are no "inches" to have "dots per..." Size is measured in pixels. That's the same on your camera. It doesn't take 10 x 8 or 6 x 4 shots. It takes shots measured in megapixels. For instance 4,000 x 3,000 is a 12 megapixel camera.
Using that example, that shot from that camera has 12 million pixels. So that's how many "Dots" there are. To decide the ratio of dots per inch, you now need to decide the "inches" part. And that's printing. Print at 10 x 8 and the dpi will be 4,000/10 or about 400 dpi. At 6 x 4 then it's 4,000/6 or 660 dpi. Work the other way: Print at 300 dpi and the resulting image will be about 13 inches on the longer side.
So, your photo as a fixed number of pixels. Changing the dimensions of the print will vary the dpi, changing the dpi will vary the dimensions of the print.

Xorg DPI settings won't save

Following the wiki, I decided to check if my DPI settings were correct, and fix them if they were not. These are the results I'm getting (full commands typed out for clarity):
First, without any configuration, the screen settings:
$ xinit /usr/bin/awesome -- :0
$ xdpyinfo | grep -B2 resolution
screen #0:
dimensions: 1920x1080 pixels (508x285 millimeters)
resolution: 96x96 dots per inch
This is wrong. Altering the commandline -dpi parameter results in the following:
xinit /usr/bin/awesome -- :0 -dpi 165
$ xdpyinfo | grep -B2 resolution
screen #0:
dimensions: 1920x1080 pixels (295x166 millimeters)
resolution: 165x165 dots per inch
This is right. For a more permanent solution one might alter xorg.conf settings, which I did:
/etc/X11/xorg.conf.d/10-dpi.conf
Section "Monitor"
Identifier "Monitor0"
DisplaySize 295 166
EndSection
However, it results the default 96x96 DPI, as you saw in the first code snippet. Furthermore, directly editing the DPI in xorg.conf such as this:
/etc/X11/xorg.conf.d/10-dpi.conf
Section "Monitor"
Identifier "Monitor0"
Option "DPI" "166 x 166"
EndSection
again results in the default 96x96 DPI.
Interestingly enough, if I deliberately put some bogus values into the config, Xorg complains about it and will not start up. So the config file IS being read, and there are apparently no errors in it. As well the other .conf files in the /etc/X11/xorg.conf.d/ directory is working (such as fonts.conf, which I am using to include /usr/share/font directories).
Why is the config not applying?

I looked this up also, and found that Xorg0.log gives different results then xdpyinfo :

No 90-monitor.conf file present, and Xorg.0.log only has 2 other lines with dpi , both about font paths.
So the question seems to be : which is right, Xorg.0.log or xdpyinfo ?
Interesting... The xdpyinfo one is correct (I can tell because of text sizes). However, when starting X without the -dpi argument it shows this:
[ 2194.180] (**) intel(0): DPI set to (174,171)
Not only is this the wrong DPI for my monitor, but it isn't the actual DPI that X is using. xdpyinfo correctly displays that the DPI is 96x96. However, if I launch X with the -dpi argument then Xorg.0.log will report the correct DPI (what I set it to). I really have no idea what's going on. I just wish my DPI settings would save!

Export QuickTime Settings

Does any one try to Export QuickTime Settings with applescript?
For example:
tell application "QuickTime Player"
tell first movie
save export settings for QuickTime movie to file filePath replacing yes
end tell
end tell
It is working perfect with original QT Settings.
I tried to install Flip4Mac free version and export QT settings for ".mov" to ".wmv", but the file it created does not played in Windows Media Player.
I notice that Flip4Mac free version only can export 30 seconds movie, does any body could successfully complete this job with FULL VERSION?

I tried to install Flip4Mac free version and export

I don't understand what you mean. You mean, switching containers from MOV to WMV? WMP has certain codec requirements, I suppose, just as Quick Time does.

Poor quality conversion/downsizing with Aperture Export

I have noticed a difference in quality of exported JPG files, depending on if I downsize them manually, ahead of time, using an external editor (PSE) or if I let Aperture downsize them during export. The images downsized in PSE are noticeably sharper than the ones downsized by Aperture. Originals are high res JPG files from my D90 that I have converted to TIFF and touched up using PSE as an external editor. I would like to keep the full size, adjusted TIFF file as a master and just export to whatever size JPG is needed at the time. With the low quality Aperture exports (compared to downsizing first in PSE), I am having to individually downsize each TIFF in PSE prior to exporting as a JPG in “original size” mode (vs. letting Aperture handle the downsizing). Has anyone else noticed this degradation when exporting/downsizing in Aperture2? Is there any work around? Any comments would be appreciated! Thanks! (All export was done in JPG quality 10, with no pre-sharpening performed.)

Firstly, using window>show movie info, find out what the current bit rate is of the original movie.
When you come to export, keep the bit rate as close as possible to the original bit rate, keep the resolution the same as well as the frame rate. You should hopefully get much better quality.
