Which aperture setting takes sharper images. f/8 or f/11?

I have t2i (550D) and two lenses i.e. 18-55 mm and 55-250 mm. Any idea how to take sharper images of landscape by selecting a particular aperture setting? I read on a different forum that for sharper images f/8 or f/11 are the ideal settings. Any suggestions?

Seems this topic is having many hits so let me give some more info that might be useful to all:
When you need to know real detail analysis of a lens, there is no better place to check than:
PhotoZone
Specific to your question are the 2 links below. Just scroll down to MTF or Modulation Transfer Function also known as spatial frequency response (Way sharpness is measured objectively) That let you know exactly what you wanted to know about the sharpness.
Link to EF-S 18-55mm IS
Link to EF-S 55-250mm
The site should be very useful for any one eager to know specifically a detail about any lens so enjoy.

How will Aperture treat Nikon raw images which have been enhanced using Capture NX2 software? Some are cropped and "developed" and some have been enhanced using the control point technology. I have NIK sw as a plug-in in aperture.

How will Aperture treat Nikon raw images which have been enhanced using Capture NX2 software? Some are cropped and "developed" and some have been enhanced using the control point technology. I have NIK sw as a plug-in in aperture.

Actually, there is a Nik/Nikon connection — but I am pretty sure it is irrelevant to the OP's question. The connection is that Capture NX2 was written as a joint venture between Nikon and Nik. (The name similarity is a coincidence.)
Capture NX2 is a cool program that incorporates the features of Nik's Viveza and Nikon's Raw processing engine, along with some other powerful image adjustment features. It provides, like Aperture, a losses workflow. Unlike Aperture, the adjustments (Edit Steps in C-NX terminology) are saved in the original NEF file along with the un-altered raw data. Multiple versions can be saved in a single NEF.

Image cannot be rendered because Aperture does not support image format

Dear all,
I have installed apple Aperture 3.03 and the complete Nick software plug-in selection:
• Dfine 2.0 for Aperture
• Color Efex Pro 3.0 Complete for Aperture
• Silver Efex Pro for Aperture
• Sharpener Pro 3.0 for Aperture
• Viveza 2 for Aperture
History
Until a few days ago the system was running ok / no notable issues on performance. / all pug in seem to run good / no issues. Also
• I Run OSX10.4/ Aperture 3.03 ( 32Bit mode)
• My library contains just over 10000 images / approximately 140GB
• I have recently updated the OSX software update including the security update 2010-005
• as well as the Snow leopard graphic update 1.0
• As far as I am aware all updates where automatically recommended by OSX Software update ( no manual intervention).
• As far as I remember after update the system still was running ok but honestly I can not tell you how many times the Nick Plug in started out of Aperture.
After all, Several times I continued using the system / still no noticeable problem until the following was happening:
Problem:
After creating with "PT gui" a panoramic image File type: "TIF" Pixel size: 5112 × 2556 (13,1 MP) I imputed this file in to Aperture (drag and drop). During the attempt to eddied this file with "Nick Define 2.0" the system was hamming up No response for several minutes from Dfine 2.0 / Aperture" At the end I had to "force quit" the applications.
After the consequential reopening of Aperture I tried again to eddied images with any Nick software Plug-In but each time Aperture prepares any image previously stored in my Library ti open the Pug in the following Error message appears:
*"This image cannot be rendered for editing because Aperture does not support the image format"*
Currently non of my previously in the library safed images can be opened in a Nick software Plug-In this applies to all file types I have tied " Raw, tif, jpg"
• I am still able to eddied normally with Aperture ( so far I do not find any other issue)
• A newly imported Raw image after being taken with my EOS 5D can be edited in the completed Nick software Plug-In selection ( so far I do not find any other issue)
The following actions have been taken to overcome the issue (all not successful):
• I restored my Library out of my back Up ( to previous time of event ( no Time machine back up)
• Uninstallation of all Nick software Plug-In selection
• Uninstallation Aperture Reinstallation Aperture / Nick software Plug-In selection
• Repairing the library ( all three possibilities)
• installation of latest EOS utilitys
Questions
• Can you support me to overcome this issue?
• Have you heard similar issues of Nick user Running the Aperture plug-ins?
For me it is really strange that even after replacing the the library in my normally not connect back up the problem still exists (this should be not affected by the event as the back up was not done any more) / new imported images are editable with the Plug-In.
I would be happy if you could support me in this issue.
Best regards,
Matthias
PS: I have reported this issue to Apple (via Aperture feedback) as well as contacted the Nick software support and currently waiting for feedback.

Dear Ma-Le / All
I have just had the same problem
I use
• Aperture 3.03 with a iMac 2.8 Intel Core 2 Duo with all files on external hard disks (mac extended fomat as apple suggests) with referenced masters.
• Camera Nikon D300, with probably 75,000+ images on 2 hard drives
• Photoshop CS2 with PhotoTools 2.5 plugin
This has been working perfectly until yesterday when the system froze when I was using PhotoTools 2.5 with Photoshop CS2 - as a result of which I resorted to a force quit.
Since then on most of my files it has not been possible to use an external editor.
A message appears saying: *Editing Error - This image cannot be rendered for editing because Aperture does not support image format*.
The problem seems to apply to the attempted use of any external editor (including Noise Ninja)
The following have each been tried, all unsuccessfully:
- Using each of Aperture's library 3 first aid options
- Rebuilding directory using Diskwarrior
- Checking for virus using Virus Barrier X4
- Defragmenting library hard disk using TechTool pro
- Changing permissions settings
- Using Disk Utility first aid to repair permissions and checking main disk
- Removing some plist elements when open 'show package contents' of library
- Setting up a(n almost clean) new system, with newly loaded version of Aperture, with a new library from a vault saved prior to the crash when the problem first occured
Several things seem to me to be totally bizarre:
1 - The problem is the same on the other library hard disk which was not in use at the time
2 - The problem still occurs when a back up vault saved prior to this problem is loaded - using a new hard disk with a new system and a newly reloaded and upgraded Aperture software
3- The problem seems inconsistent. It appears to affect some photos but not all. Even from the same shoot, some photos can be edited using an external editor, whilst others cannot (but as far as i can tell most of the photos in a particular album seem to be consistently affected)
4- The only way around it seems to be if I import a new (copy image) from the original master. Then everything works ok, and I can successfully edit that copy image in photoshop / phototools plug-in.
I am beginning to wonder whether what has been corrupted is Aperture's ability to make copies from the master file which it then uses with the external editor (I have no real idea whether this is correct)
Does anyone have any ideas or solutions - or has anyone else been suffering a similar problem?
Eric
PS: As a professional photographer this problem is a really serious issue for me - and I really don't really want to go to Lightroom or Capture One

Can Media Encoder take an image sequence in the watch folder and turn it into a video file?

I'm using OSX and Media Encoder 6 (from premier 6) and can't figure out how to make the watch folder take a .jpeg or .dpi sequence and turn it into a single video file.
I tried copying all the stills into the watch folder, that made 60 individual video files (one for each image).
I tried making a folder inside the watch folder, and copying all the images into it.. to which Media Encoder did nothing.
What am I missing? Will Media Encoder take image sequences and render them out as a audio-less video for me?
Thanks for any imput.

Hi action_packed,
This is from the documentation: http://helpx.adobe.com/media-encoder/using/add-items-encoding-queue.html
Still Image Sequences are not supported as source footage through Watch Folders. If a set of still images is placed in the folder being watched, each individual still file will be added as a separate item to the Queue rather than than the entire sequence as a single piece of footage.
Make a feature request for that here: http://adobe.ly/feature_request
Thanks,
Kevin

Locking Aperture Setting in Movie Mode - Canon T4i

I recently bought a T4i to use for shooting short videos, some of which will require me to zoom in during filming. I noticed that if the scene is properly exposed and I zoom in, the image becomes darker. This is not much of a problem sinceonly a short amount of footage will be seen before the zoom starts, so I can just expose the image so that it looks fine after the zoom.
The issue is the when I zoom in, I noticed the camera is automatically adjusting the aperture. I'm using the Manual mode, not Shutter Speed Priority. The ISO doesn't change and the Shutter Speed doesn't change, so why is it compensating by adjusting the aperture? Is there any way to lock the aperture setting in Manual mode? Is there is an auto compensation feature that needs to be turned off? As far as I can tell, Scene Intelligent Auto is off, as is the Auto Lighting Optimizer. What am I missing?

This depends on the f-stop and lens being used.
You didn't mention which lens, but the "kit" lens that comes with the camera (if you buy the camera as a kit) is the EF-S 18-55mm f/3.5-5.6.
A lens normally lists it's WIDEST possible aperture, but notice that the focal ratio for this lens (f/3.5-5.6) is listed as a range.
This means that the widest possible focal ratio is variable and depends on the focal length. At the 18mm end, the lens is able to provide an f/3.5 focal ratio. But as you zoom in, this ratio increases to f/5.6.
If are using a low focal ratio such as f/3.5, then yes... the focal ratio will increase and the image will get darker as you zoom in. That's the physics of the lens. There are better lenses such as the EF-S 17-55mm f/2.8 IS USM. That lens is able to provide an f/2.8 focal ratio (which is even brighter) and can do so at all focal lengths. The f/2.8 focal ratio collects considerably more light (the lens is physically larger).
If you set the aperture on your variable focal length lens to the higher f-stop in the range (e.g. f/5.6) then the lens CAN provide that focal ratio at all focal lengths... hence it will not get darker as you zoom... this assumes you have enough light.

Copying Aperture Library takes forever

I 'm creating an off site backup for the first time as it's something I've been meaning to do for ages. Its not a fancy affair, just dragging and dropping the folders I want. I have numerous on site backups that are all in sync etc so this method should be fine.
Any way, when it came to copying my aperture library, which has almost 26000 reference images and is almost 32GB, things didn't go well. It was telling me that it was going to take 26 hours, and the time was rising, for it to copy. I have seen something similar with iPhoto but not nearly on the same scale.
What's causing this and how can I fix it? I could put a vault on the drive via aperture which doesn't take to long, but I'd really prefer to have the original library on the backup. I am currently trying to compress the folder, and although the size won't really change, it may(?) speed up as its copying an archive rather than the library.
Any ideas?
Regards

how old is the library? I experienced the same thing when copying my AP3 library to an external..it's a 48GB library with 70,000+ referenced files...estimated time did not move up to 6 hours like yours, but it did go up to 2, which is too long to copy 48GB via firewire 800...
I let it run, and total copy time ran about 30-40 minutes. There were patches where things got really slow, then other patches where they sped up again.
I would take a look at this thread
http://discussions.apple.com/thread.jspa?threadID=2343039&tstart=0
specifically reply #10..as my question about long copy times and disk fragmentation was addressed there.

How long does creating a Aperture vault take?

I recently migrated my iPhoto images to Aperture. All 180gigs worth. Currently, i'm in day 2 of creating this vault of images, and it's only halfway done. Aperture shows it is still "copying masters", and if I check force quit Aperture is still responding. Is this common?
I'm on a iMac which is about 2 years old. I'm using OS 10.6.8. All my origional master images are stored on a external HD so I don't load us the internal space, and I'm copying to another external.

Hi. Thanks for the input. It's good to hear that this does take time.
My iMac has the intel core 2 duo. proc. speed 2.66GHz and 1GB DDR3.
One GB of RAM? That's it? I don't have time to check, but I think the minimum listed by Apple is 2, and that's not enough. You'll need 4 to run Aperture successfully (and that's without multi-tasking), 8 to run Aperture and multitask (real-world minimums).
That alone could account for the slow performance you are seeing.

What I'm trying to do is creat a backup of all my images - some 31,000, to include all post production adjustments, metadata, etc. Reading in Aperture that if I back up with out using the vault then all the data associated with each image is not present if I need to restore my origional library.
You Library is a Finder file package. (A package shows in Finder as a file, but is in fact many files.) Everything Aperture knows about your Images is in the Library. Ergo, if you back up your Library, you have backed up all the information about your Images.
The Vault is simply a differential back-up program built into Aperture.
I backup my Libraries by copying them to external drives.
Your Images' Masters, however, may not be included in either a Vault or in a back-up (or copy) of your Library -- that depends on where you have told Aperture to put them. If you told Aperture to include them inside your Library (as Managed Masters), then they are included in the Vault (as well as in any backups or copies of the Library file). If, otoh, you told Aperture to store them elsewhere, then neither your Vault nor any backup or copy of your Library will include them. In that case, you are responsible for backing them up using some program other than Aperture.
To restore a lost or damaged Library, you need a copy of your Library and copies of any Masters which are not included in your Library.

I have my origional Aperture library on an external HD because of it's size, 180 gig. My iMac only has 320 gig, and the whole family uses it. Currently I only have my masters (origional library) on this one external drive, then I do backups onto dvd's.
Are your Images' Masters Managed or Referenced? Let's clarify that, and then move forward.
Unless you reasons to do otherwise, I suggest putting all your Masters in your Library (every Image's Master will be Managed), putting that Library on one external drive, and either copy or Vault your Library to your second external drive (and storing it apart).
You didn't mention drive speed: I have seen a welcome difference between 7200 rpm drives with large caches and 5200 rpm drives with small caches. Some users can get by with FW400, but really FW800 should be the least you'd purchase. If you are using a USB connection, you are going to see performance slow enough to be unusable.

One trigger to take multi images

Hi All,
I am using a Guppy Pro F031b, which is equiped with Bulk Trigger Mode. This mode allow me to take multipule frames with one external trigger.
I want to take two image every trigger and save them. But I have no idea how to realize this function with with IMAQdx. Has anyone did this before and can give me a hand?
Shall I use Grab or "IMAQ get image"? Shall I use a whileloop to let the get image excuated twice or the VI will automatically grab two image?
Thank you very much!
Wen
Solved!
Go to Solution.

Cody A., Kyle T. ,
I have already programed a VI include trigger mode 0(edge triger), trigger mode 1(level trigger), and bulk trigger. I monitored the camera IO which can show me the camera exposure time. And I found after every trigger, the camera does exposure twice.
Shall I set the buffer number as 2 if I want to use bulk trigger?
How can I read out the two images in my buffer?
Thank you very much!

How to set a background image to fill the entire screen on any device in a spark mobile application

Hi,
I started developing a mobile application with Flex.
I'm trying to set a background image to fill the whole screen. I've been stucked at this point for days now. I tried everything and no solution seems to work for me.
I'm using a TabbedViewNavigatorApplication and i need to set some background images on views.
I need my image to fill the entire screen on any device. i don't need to mantain image aspect ratio, just need it to be fullscreen. This seemed to work when setting a custom skin on the TabbedViewNavigatorApplication, however this blocked all my views for some reason and all components contained in view became invisible.
Can you please tell me how can i achieve this?
Kind regards,
Dan

Basically you need a larger image which can accommodate any device. The trick is to show only what each device can display, so therefore some clipping will occur based on device. Have something centered and towards margins have a gradient or just plane colors that way the stuff in the middle will be visible on every device while nobody will care if you are clipping from the color fill.

Can I take an image created in Illustrator and have it be on the Character Map? I need to use it as

I have an image that I need to use as a bullet many times for a specific client. Is there a way to take that image from Illustrator and convert it to something on the Character Map?

If by Character Map, you mean the Windows Character Map application, which lets you view the glyphs in a given font, then no, you can't do that with Illustrator.
In order for your bullet (a new glyph) to appear in the Windows Character Map application, it would have to be a glyph inside a font.
Illustrator does not provide the capability of directly editing font files. (Corel Draw does.)
So if you want to edit an existing font, or create a new font, you need a program that can edit and/or modify fonts.
In modifying fonts, you would be restricted by the limitations inherent in fonts: your custom bullet or dingbat would need to consist of a single simple or compound path, and could only receive one color, as any other text object.
The far more common approach to this problem is to use inline graphics. All of Illustrator's mainstrream competitors (and even InDesign) allow you to paste a graphic into a textframe, inline with the text, and have it behave as if it were a character in the text. Illustrator has never provided that commonplace feature.
If you use InDesign you can, as a ridiculously cumbersome workaround, create your text object in InDesign, paste the artwork element(s) inline. When done, copy the whole text object and paste into Illustrator. It will be pasted into AI as PDF content, meaning a Clipping Mask containing a bunch of individual pointType objects and the bullets as separate objects.

How to paste exposure setting to multiple images

Hi all:
I know this question has probably been asked many times but I couldn't find any answer using the search so please be patient with me. :)
I came from the world of RawShooter Premium and I realized that my version of RSP can't read RAW file from the Canon 30D so I got the Adobe Lightroom to process my images. All is well until I decide to paste the exposure setting from one image to multiple images. I know there is a copy and paste button in the "develop" mode but it doesn't paste the settings (color temp, exposure, noise, etc) to all the images even when I highlighted the images I want to paste. I can do that in RSP, which save a lot of time.
Can anyone shed some light on this? I would really appreciate it.
Thanks in advance.
Ben

In develop, copy and paste only works on the selected image. You can sync or auto sync (control-sync) there.
If you want to copy and paste to multiple images using shift-control-C and shift-control-V, you can do that in grid mode.

Type exactly whats on here on your settings.
Procedure:
1- Turn on your phone
2- Get paperclip take out tray and put your non working sim card in- T-moble and simple mobile sim cards work great for me on this venture.
3. Goto Settings>General>Cellular>Cellular Network
At this point its very critical that you do this fast, Once you change the sim card to your net 10 the option Cellular Network will only stay on for a few seconds while it's searching for service. You will need to click on cellular once the Net10 sim card is in and click on Cellular network again.
4. Get your paperclip take out the tray put in the Net 10 sim card
5. Goto Cellular>Cellular Network while it's searching for service
6. Type in your settings that I list above
7. Scroll back to your main setting (Do not press your Home Button)
8. Once you see your service up and running try out your web and send a picture message it should work.
9. If it does'nt work you mistype one of the settings, it has to be exact or it wont work.
10. Do the process all over again
Keep this information and the sim card away for a later date in case you lose your setting I have'nt turned off my phone or let my battery die to find out if I lose my settings. One thing for sure I lost it when I update to the IOS 6.0.1.

The value should be set for Base image URL and Image file directory

Hi experts
Now customer has the following issue.
XML Publisher concurrent request, using RTF layout template with LOGO, does not generate the LOGO for Excel output.
but in output formats PDF, it is shown normally.
from the debug log, we can found the following error message
======
[051812_054716051][][ERROR] Could not create an image. Set html-image-dir and html-image-base-uri correctly.
======
so I tell the customer to do the following action plan.
1. in XML Publisher Administrator resp > Administration expand the HTML Output section.
2a. enter a value for 'Base image URI'
2b. enter a value for 'Image file directory'
Customer set the value as following and retest this issue,but he found the issue is not solved.
Base image URI: /u01/r12/ebssnd/apps/apps_st/comn/java/classes/oracle/apps/media/XXSLI_SONY_LIFE_LOGO.gif
Image file directory: /u01/r12/ebssnd/apps/apps_st/comn/java/classes/oracle/apps/media
I verified 'Base image URI' and 'Image file directory' settings:
1) Change output type to HTML.
2) Click the Preview.
but the image is correctly displayed on HTML, so I think the issue is caused by user's uncorrectly setting of the base image URL and/or image file directory
but could anyone give me some advice on which value should be set for Base image URL and Image file directory
Regards
shuangfei

First thing to do is to edit the post and use some tags to format the code as it is unreadable and too much!
Read the FAQ (https://forums.oracle.com/forums/help.jspa) to find out how to do this.
Next we need to know the jdev version you are using!
As the code is generated I would first try to generate it again after the db change.
