Using Levels in Aperture

In photoshop you can use level adjustments to select a point in an image to be absolute black and another to be absolute white. Is this possible in Aperture?
Thanks

Actually in the Exposure adjustments there are
droppers for black white and gray. Just use those
droppers to set your blacks and whites
Those do not set Black & White points in terms of levels - what they do is make whatever you click on neutral (grey) for either the lower third of the tonal range, or the upper third of the tonal range depending on which you use. The center one affects the whole tonal range. That's why they are labled "Tint".
You can however also use those droppers to get the same lines in the histogram as I had described with the White Balance control to get information on where pixels sit in the tonal range for information on where to set Levels.
At this juncture to improve clarity of discussion I think I should note that I have written an Adjustment Tool Guide that describes exactly how all the Aperture adjustment tools work and when they can be of use:

I ordered my Macbook Air with Aperture two years ago. I now have an iMac - can I use that with Aperture in any way? I appreciate that it is a different computer but I am now the end user of both devices and I was just wondering if it was possible.

The answer would be in your software license agreement for Aperture. However if you cannot locate it you can ask in the Aperture forum, the link for that is:
https://discussions.apple.com/community/professional_applications/aperture
However I believe you can have Aperture installed on two machines however only one may be using it at a time.
On the new iMac launch the Mac App Store - Purchased - look for Aperture and download to your new machine.

Learning to use Levels

I shoot a lot of underwater video and often the raw footage looks "murky" and has a greenish tinge that is corrected via Auto Levels. Is there some easy way to use the Levels effect, rather than auto levels so that you can easily match what Auto Levels is doing with the Levels effect? I've tried and it's really not that simple for me. I think I would have to correct the RGB channels first, just by sight on the tiny preview window in the Levels Setting. Then go to the green channels and monkey around some more via trial and error until I get something that looks OK.
can anyone give me some hints on how one would use levels to remove the cloudiness and green cast that many UW video clips have? Auto levels often just does this with many clips, which is why I tend to use it a lot.
P.S.
Can someone from adobe make the AUTO correctors in the adjust section of video effects GPU accelerated!

Here's a level's reference chart that should help you understand whats going on better. http://www.motionworks.com.au/2007/01/levels_guide/
Look at your RGB Parade in a reference monitor and watch what happens when you adjust 'em. Also mainly just adjust the input. The Output can really mush things up if used wrong.
Basically the adjustment on the left (when pulled right) pushes the picture into the shadows. Higher in the graph.
The one on the far right (when pulled left) pushes the picture into the highlights. Lower on the graph.
The middle, your gamma, shifts the middle or mids of the picture.
Also notices it doesn't shift the colors is pushes them. Hope this 'll start you in the right direction. Once you learn it and can go beyond just AUTO coloring and make your video looks way better.

Using tethering in Aperture

When using tethering in Aperture, is it possible to have the shots appear behind a pre-designed layout for composition control?

Allen -- Frank and Neil have giving excellent answers. Personally, I found Betty Edwards lessons to be better than her science. You might also look for Harold Speed's book on drawing (was available in a Dover edition), as well as (in a different vein) James Watrous' excellent "The Craft of Old Master Drawings". But the _very best_ advice I can give you is: don't read; draw. Just get a bunch of #2 pencils (with erasers, they have always been used), and _draw every day_. Drawing is a skill. Skill increases through repetition and active engagement. For adults, the biggest hurdle is accepting that they draw with the skill of someone who has rarely drawn (hence the exercises to "short-circuit" the squelcher in your brain). Start with ... carrots. Peel them, cut them into 1/2 to 3" lengths, set three or four pieces before you, and copy their outlines and the edges between the flat faces left by the peeler. Concentrate on the angle of the lines on the paper (vertical, horizontal, by how much), and how they correspond to the 3D forms of the carrot pieces. This is hard, but your drafting skills will have given you the (invaluable) ability to imagine forms in space. Set in the corner of your eye a meter gauging when the paper is _activated_. I'm not going to define that -- you'll have to feel for it. Learn how to tingle this awareness, and tingle it constantly.
When you feel comfortable with this, set the carrots up on a piece of paper, and after your first drawing, rotate the paper 30° and do a second drawing.
Other variations will occur to you.
And in the meantime, carry a sketchbook with you and when you see an interesting leaf, draw it.
When you're ready to try plants you'll know.
Drawing animals is hard. Start with sleeping ones.
Drawing people is _very very very hard_.
To repeat the important parts:
- draw _often_. Frequency is more important than duration. As Michelangelo said to his students: "Not a day without a line!"
- be kind with yourself. No-one was born drawing well (drawing prodigies are extremely rare -- Durer was one).
- carry a sketchbook
- stick with one tool for a good bit. Pencil is great. If you prefer something else, use it.
- learn to create form (the effect of 3D) with line. Shading comes later.
- _activate_ the page on which you draw. Red-line that little meter in the corner of your eye.
When you have schooled your hand and judgement by such diligence, you will acquire rapidity before you are aware of it.

Make 2 (4? 10?) discrete luminance levels in Aperture?

Hi. Tonight's puzzler. Is there any way, using Aperture, to create a luminance map of an image which maps every pixel to a luminance bin? At its simplest, this would take an image and reduce it to black & white (not Grayscale) -- two bins -- where every pixel above a certain luminance (user settable preferred) would be colored white (luminance = 100%) and every pixel at or below that certain luminance would be colored black (luminance = 0%).
Even at that level I could make good use of such a tool (as long as the dividing line is movable), but I really want something which maps the image to more discrete steps. The Munsell system uses ten levels, which would be good. I would be equally happy with five.
There are ways to set the Levels Brick to give four (or six) steps from a grayscale image (make a "V" or an "M" or a "W"). This is a fairly kludgy work-around, though. I've set up five different Adjustment pre-sets for different "binnings". In use it is inelegant and impractical. I have tried using multiple Levels Bricks with different Brush Ranges. Sad to report, applying this as a saved pre-set repeatedly brought Aperture to its knees.
If there are other programs which can do this with aplomb (I don't know much about Photoshop), please point me in the right direction. This is just one of several more-or-less metrical image analyses I am essaying.
As always, thanks!

Continuing the PhotoShop idea:
There is a plug-in (or there used to be!) called "filter factory" which would let you create filters using expressions that would apply to every pixel in the image. The expressions look soemthing like this:
r: if (r < 128)?0:r
g: if (g < 128)?0:g
b: if (b < 128)?0:b
which would set each component to 0 if it is less than a value of 128.
Of course, it is much more versatile than this, it would be pretty easy to do what you want with this tool.
<a class="jive-link-external-small" href="http://">http://www.creativemac.com/2002/02_feb/tutorials/filterfactorycomplete2.htm
Exactly! Exactly what I am looking for. Your link is from 2002, and I can't find any up-to-date information. Do you know if Filter Factory is still available? Has the functionality (writing expressions which are applied to each pixel) been incorporated into the current version of Photoshop?
One of my frustrations with Aperture is that, although the Bricks are the equivalent of sophisticated transform functions operating on each pixel, Aperture neither specifies what the functions are, nor lets one modify them. (I would be ecstatic if something like Filter Factory were available for Aperture.)
For instance, the Vibrancy parameter is defined in the Help file this way:
+The Vibrancy parameter applies saturation to the image in a nonlinear manner. Colors that are already saturated are left alone, while saturation is added to all other colors. In addition, the Vibrancy parameter takes skin tones into account, leaving them untouched.+
That is good to know, but incomplete. It suggests, but doesn't specify, the shape of the non-linear curve (two curves, actually -- one for saturation and another for hue). I could make much use of the knowledge of the parameters' explicit definitions. And I could I dance downtown if we were provided sliders to change the definitions.
Maybe Aperture 5.x.

Red patches using RAW in Aperture

I seem to be getting red patches in my RAW files taken using a Canon 30D. I think its something to do with the exposure in Aperture but it only occurs with RAWs. It does not show up in JPEGs.
Anyone have any clue as to what might be causing this?
Screen capture.
MBP 17" C2D 2.33Ghz Mac OS X (10.4.9)

What berj said.
If you use Auto Exposure, you may see the red "hot" areas increase notably. At least to my taste, in the setup for the 30D the Auto Exposure button often bumps exposure way too much. I end up not using that much. The Auto Levels buttons are much more useful.

Using Fotomagico with Aperture

Hello,
Does anyone have any experience using the slide show program Fotomagico with Aperture? It has a feature where you can access your iPhoto libraries easily to create slideshows but doesn't seem to have the same access to the Aperture libraries. A
Has anyone discovered any workaround for this or do I just have to export images into a folder and use them that way.
Cheers,
Lisa

The reason you cannot drag-n-drop right out of Aperture is really quite simple.
It would involve the same steps as you exporting a version.
The photo you see in iPhoto is either the original imported JPG, or a JPG from the imported RAW file, or a modified JPG(if you have made any enhancements/cropping to the image), so dragging and dropping works well there because you are merely copying a file from the filesystem to the application.
IF you could drag-and-drop from Aperture, users would complain that it is too slow, and much slower than silly iPhoto! The reason it would be slow is it would involve a full rendering of a new JPG based on the changes you applied.. this would take just as long as exporting the image the old way.
Ever made a change to an image in iPhoto? When you move to the next it tells you to wait while it regenerates the new stored image. Imagine Aperture doing that! No thanks!
I have used Fotomagico(which IMHO is THE choice for slideshows) with images from Aperture. I make an album either at the project level or the folder(of projects) level and drag in the images I want to use for the slide show. Once I have made those choices I export them all to a folder and point Fotomagico at it. Works great!
I am sure V2 of Aperture will have some sort of slideshow tool built in, but probably not as robust as an external dedicated app like Fotomagico.

How do I use iCloud with Aperture?

I want to synchronize the photos I shoot and load on my MacBook in Aperture to my desktop iMac. I've never used iCloud, but the setup instructions says this should work for Aperture users. The instructions say:
"Open iPhoto or Aperture and click the Photo Stream icon in the left column. Then click Turn On Photo Stream."
Well, there is no Photo Stream icon in the left column or anywhere in my Aperture program. What am I missing? Thanks for any help.
Maria

Maria, have you enabled Photo Stream in the System Preferences > iCloud tab and in Aperture's Preferences?
Does your Aperture version support iCloud? You need at least Aperture 3.2.3
See: iCloud: Photo Stream FAQ
Choose Apple () menu > System Preferences. Click iCloud, then select Photo Sharing.
Turn on Photo Sharing in one of these applications:
iPhoto: Choose iPhoto > Preferences. Click iCloud, then select Photo Sharing.
Aperture: Choose Aperture > Preferences. Click iCloud, then select Photo Sharing.

Using Macbookpro with Aperture photos on external hard drive

I have now just about filled up my macbook pro. So I am now moving my pictures folder to an external drive. I have never done this before but it looks straight forward. After the transfer I just restart aperature and help it find the library.
But here is the question. I would like to bring my laptop on trips, take pictures, manipulate them in aperture. Then when I get home I would like to put those photos into the external drive.
I am confused about how to do that?

Bob,
I am currently using MacBook Pro 2.4 GHz with 4 GB DDR2.
Since day one I have used an external portable hard drive that has all images stored on it.
No images are stored on the MacBook.
Currently I am using a portable LaCie 250 GB running with Firewire 800.
Nearly 10,000 images at the present time.
Use a USB 500 GB portable external hard drive for the Vault (backup).
Have had no problems working this way.
I am looking to purchase a larger portable LaCie (500 GB) soon.

How to use iMovie with Aperture Library from an external drive?

Hey,
Some problems:
1. My first video, I stored the project on my own laptop and used the library from the HD. This seems to give some problems, but I now figured out I have to consolidate the media etc. so now my files don't get missing after unplugging the harddrive. I figured it would be a better idea to make all new projects on the HD, so I have everything in place all the time. BUT. look at the picture: there seems to be something wrong with the way iMovie recognizes the aperture library: i'ts not listed in the events library under the HardDisk (named Passport) but under my own drive... ??? (+ I don't understand the idea of events when I have my aperture library: Do I need to make events for all projects I make? how is this possible when the library is not in the correct position?)
2. I made a movie, but I'm unable to export a large/high quality version of this project. That's why I want to move my project to the HD and then open it on my partners Mac Book Pro to make a good export. Unfortunately, his macbook doesn't recognize the files and the files can't be opened in iMovie... (files stay gray and unclickable)
To sum it all up:
I want the best way to work with this set-up: mac book air, external drive with all my files and iMovie. And I want to be able to open the project on a different computer to make high quality exports.

First thing that comes up with videos in your 'picture' library is the videos are always under the full control of the picture library program. Which means Aperture is the keeper and master, and it decides what will be displayed in iMovie's Event Library. If Aperture is having difficulties sometimes it cannot or will not display the videos you are storing there.
Right now, I think the problem is your Aperture Library is on the internal Mac HD, not the external. You would have to move Aperture's Library to the external HD (along with all the pictures and videos). Then try to add the videos back into a project.
In extreme cases I have recommended moving the videos out of the picture library and re-importing them into iMovie Event folders to let iMovie manage it.

Using Photoshop With Aperture-Flattens Layers

I am running into some slight issues when using Aperture 3 and Photoshop CS6.
I have used Aperture 3 for quite some time. As part of my workflow, I use Nik Software plug-ins for quite some time. In order to fully understand the issue, it would be best to understand a bit about my workflow.
After I go out and shoot the images, I download the images onto my internal drive so that the images are managed within the library.
I then proceed to rate the images. When the library is imported all the photos get one star.
I then go in and star photos that deserve a two star rating.
With these photos I take all the two stared photos and use the NIk Define plug-in to decrease the noise of the images. After this process this outputs TIFF files that are placed into my library.
I then make all these new TIFF files that have the noise lessened to three stars.
Previous to my new workflow, I would go from here utilizing the NIk plug-ins and then further rating the images.
New Workflow:
From here I enabled Adobe Photoshop CS6 is an external editor.
I would export the images I would want to work on in Photomatix Pro to my desktop. After using Photomatix, I would open up the file in Photoshop without importing into Aperture.
After all my work is done in Photoshop, I would reimport the photo back into Aperture 3.
While the file was in Aperture 3, I would reopen it in Photoshop.
The file would show as my layers being applied but not shown. I think it was a flattened image file.
What I would like to do:
Be able to reopen with Photoshop photos in my Aperture library but continue preserving the layers from Photoshop.
Would I need to save the files as PSD files in order for this to work? Any thoughts?
Anyhow for device would be appreciated.

leonieDF wrote:
Aperture does not handle layers, as far as I know. If you import an image with layers, as tiff or as psd, the layers will be preserved, but not displayed with transparency, since Aperture does only handle RGB. If you export the original (master), your layers will be preserved, but if you adjust the image in Aperture and export the edited version, then the resulting file will no longer have layers, all will be flattened.
If you Aperture only use as a database and not as editor, your approach should work, but if you want to use Aperture's editing tools and export versions, then the layers will be gone.
Sorry to revive this old thread, but I have a follow up question on exact subject...
I have run into the same issue and understand your explanation. I have confirmed that I can import a layered master to Aperture, its layers are preserved and if I export it later the layers are still there.
What I am really surprised about is that if I edit in Photoshop from Aperture, the file opens up in Photoshop, but the layers are not there. Is this right or avoidable?
Thanks
