Any Photo editing tips to help with my wildlife photo contest entry?

I'm admittedly not the greatest with Photoshop, but I'm definitely an excellent photographer. Is there anything that Photoshop can offer in terms of making my wildlife photos look more 'life-like' for when I enter these photos into a wildlife photo contest? Any help is appreciated.

You are only allowed minimal adjustments in every Natural History competition I have ever heard of. Brightness and contrast sort of thing, and maybe - at a stretch - tone down distraction elements. But competions bring out the worst in some people, and I know a few who cheat.

Tips and help with re-installing Lion over Snow Leopard

I had MAJOR issues with my initial Lion install on my Mid-2009 MBP- so much so, that I had to wipe my hard drive and re-install Snow Leopard and all my applications. My major issues were as follows:
1. All my files were locked out- I could open them in most cases, but I couldn't overwrite them- Lion had aded some funky permissions scheme that I didn't recognize, and my user name wasn't present on any of them. In some cases, I couldn't even open files, even though they were resident on my hard drive (and in my own user folder) before the upgrade to Lion.
2. Apple's own Universal Binary apps wouldn't work after the upgrade. Final Cut Pro 6, in particular, came up with a message that it was a "PowerPC" app and wouldn't run- yet Shake 4.1 would run just fine!
3. Adobe Creative Suite 3- after the upgrade, my Abode Ceative Suite 3 apps worked just fine, for about a day- that is, until I tried to correct the file permissions issue by changing permission on a few of my folders in my User folder (and electing to change permissions in the files contained therein)- at which point my Adobe apps told me that they were damaged and needed to be reinstalled. Yet after uninstaling and reinstalling the entire Creative Suite 3 times, I still would get the same message.
My entire workflow is Adobe CS and FCS2- why chould I have to pay the upgrade costs just to use Lion? FCPX is completely brkoen for my workflow and eqipment, and Adobe can't even guarantee that CS5 works with Lion- so why does Apple insist on Lion when it's hardly even compatible with its own products?
I really want to use Lion, but I am looking for some tips on instalation to kep these problems from happening again. I didn' have ANY of these problems with upgrading OS 10.2 through 10.6. Any help with prepping my system/files for upgrading would be helpful. Thanks!

Me, I think clone backups are more useful, and only use T.M. as secondary.
Using Cloning as a Backup Strategy
I'd assume that professional apps may need to be tested still; and of course check to see what you have that depends on PowerPC code and Rosetta first. That has some in a tither.
A clone lets you still be able to boot Snow Leopard. Check out Carbon Copy, SuperDuper.

Aprimo and InDesign integration... Curious if any 3rd party programs can help with this. Thanks!

We were promised that Aprimo played nicely with Creative Suite, although now that we're getting our hands dirty, we're finding this is not the case, and our Aprimo contacts haven't been much help. Has anyone out there found a way to make this work? Thank you for any notes & recommendations!

Aprimo’s Marketing Resource Management (MRM) solution has Brand Asset Management functionality.
A full enterprise digital asset management solution like North Plains TeleScope can understand creative tool work flow, allowing users to work with complex, multi-asset documents such as InDesign without needing to manage each asset individually.
A solution involving a strong Aprimo-TeleScope integration off ers companies the best of both worlds. It would impart great value to all who need Enterprise Digital Asset Management and also want to manage their campaigns and marketing processes more eff ectively.
We at Capgemini have a Center of Excellence for Integrated Marketing Management where in we have expertise in building Aprimo's MRM as well as North Plains TeleScope solutions.

Any Luck Editing Actions on Events with ASA SSM

W are running an ASA 5540 failover pair with SSM-40 modules. When using the IME version 7.0.2 to manage the IPS we have not been successful in getting anything to work but "Deny Attacker Inline." Nothing else works. We have tried every option under the Actions and none work. There are many signatures that we would like blocked, but only that signature. ie. block Bittorrent but allow internet access.

If you manage the device through ASDM or IME should not make a difference.
What I would suggest is to test the action on a simple signature, like the ICMP ones (e.g. Sig 2004, you have to enable it first) and not a complex one like P2P etc.
Also what is exactly happening with the other actions? Do you see the signature fire in IME with the 'action' listed? Or the action field is empty in the IME alerts? Or the signature does not fire at all?

Please help with Posting Keys For Fast Entry (t.code OBXJ)

Dear experts,
Please help me to be more familiar with configurtation of Enjoy Transactions (t.code OBXJ). I want to configure fast entry transaction and change standard assignement of posting key. But there are no editing options in this transaction, just three transaction keys are predefined and posting keys are assigned to them (those are changable). But where to see what those transaction keys mean? And what could be your proposals, how to configure this IMG step?
Thanks!

Hi,
t.code OBXJ is for automatccly postings, normal you never change the standard posting keys.
In the block line items you can select colums you need and place the one's you need to the begin of the screen and in the right top corner of posting line items you can click an save this as (default) variant.
When you want to use an other posting keys you use the option complex posting (F6)

Help with Web Server error log entries.

I'm having trouble turning off logging of messages from the iAS plugin to
the Web Server error log. It seems to be logging "Info" class messages to
the logs.

New Mac user looking for help with Finder, Preview, Keyboard, & Dock

So about a month ago I switched over from a lifelong Windows user to a brand new MacBook Pro, and while I am adjusting pretty well, there are still some things that I haven't quite figured out.
First up on the list is Finder! I like my files to be arranged just like how they are in Windows Explorer--folders first alphabetically, then files alphabetically. I've managed to acquire this setting by messing around with the "clean up by" and "arrange by" functions but I don't really know the specific combination. Most of the time these preferences are saved and set as the defaults under "View Options" but every once in a while it resets and I have to tinker around with the settings all over again. Does anyone know of a way to fix this? It's only happened twice so far, but I'd rather not have it happen again. Also, occasionally when I delete an item, there is a blank space left where the icon was instead of all the files following it bumping up a space. Any quick fixes for this bug?
Next up is Preview. Again, I like the Windows Way and I like to be able to browse between the files in a folder while using Preview/Windows Photo Viewer. I know that there is a way to browse between files if you select the whole folder and stick it in Preview, but is there a way to achieve the same result without having to do that? An app or "extension" of some sort that adds arrows in to browse between photos? I've had no luck finding anything other than the aforementioned option. Is there a good free alternative to Preview that will function similarly with the browse between photos option?
One of my favorite things about my new Mac is the backlit keyboard function. My old laptop didn't have it and as someone who is online more often at night it is super helpful. But is there a way to turn it off during the day/in bright settings? A way to put it on a timer? In System Preferences I selected the option "Adjust keyboard brightness in low light", which I assumed to mean would have the keyboard NOT very bright when there IS light, but it continues to light up just the same. Any apps or extensions to help with this one?
And finally, the dock! This question is more about aesthetics than functionality but help is appreciated all the same. Currently, my dock looks like this: http://i42.tinypic.com/35ktxlz.png It is rather opaque and the indicator lights can barely be seen. However, in a lot of tutorial videos I've been watching, many people have docks that look like this: http://i.i.cbsi.com/cnwk.1d/i/tim/2011/07/19/Lion_LaunchPad.png It is a darker shade of gray, the divider is dashed rather than a straight line, and the indicator lights are clearly visible. Does anybody know how to get this look for the dock? I've looked in the dock preferences but there's not really anything in there other than magnification/size/effects.
That about sums things up! I'm sorry if any of these seem like "silly" questions but they are all things I have been unable to find answers for. Any and all tips, tricks, and help is appreciated! Thanks in advance for all your help!!

congratulations on coming over from the dark side.
Seems like you are interested in column view, which would show you the hierarchy of folders and files: Column View in Mac OS X Mountain Lion - For Dummies Not sure what's going on if your finder settings don't stay put. May be a corrupted preferences file, which is easy to fix, but is perhaps a topic for another discussion.
What I'd suggest is to have an open mind and try to see what the mac can do, rather than force it to look like your windows machine. I mean, if you just want it to look like windows, then why bother switching? If you give it a little time, you'll start to appreciate the mac way of doing things, and see how it is infinitely more awesome, powerful, creative, intuitive, and better designed (and the software way better written) than what you left behind. But that's your call.
There are some threads on this forum with complaints about the backlight. Keyboard backlight settings query...: Apple Support Communities Evidently it depends on the angle of the screen and the light sensor relative to the light. Some suggest that a SMC reset may help: Intel-based Macs: Resetting the System Management Controller (SMC) This is not an issue for me, I just adjust the brightness with the keyboard buttons if I want. Real men shift their own gears, drink their coffee black, and adjust their own keyboard brightness. I am not aware of any software to exert more control over this feature but a search of macupdate Download Apple Mac Software & iPhone Software : MacUpdate may help. I mean, it's up to you what is important. I can waste a lot of time playing around with the GUI and with unnecessary software, or I can just get my work (and play) done.
You might prefer the no-glass dock, that removes the shelf, and makes the indicator lights like more discrete orbs. You can do this with the terminal. Using the terminal is also, perhaps, a topic for another discussion.I like the 2D dock much better. If you want I'll give you some directions for how to do it. Otherwise, here's a reference: 2D Dock - MacRumors Forums

Help with Optiarc AD-5630A causing sleep problems

I have an original Macbook pro 17" 2.16 Ghz Intel Core Duo, 120Gb hdd, 2Gb ram.
The original superdrive fried, so I had to replace it. I picked up an Apple MacBook Air external USB superdrive and removed the drive from the enclosure to replace my fried one. I believe my old drive was a mitsumi, the new one is a Sony NEC Optiarc AD-5630A with firmware 1CHQ
Ever since I replaced it, here's what's happening, and I can duplicate the problem reliably.
If I put the computer to sleep (closing the lid or otherwise) with a disc in the drive, it becomes un-responsive after the computer wakes. Console logs show a constantly looping error:
8/24/09 5:53:23 PM kernel IOATAController device blocking bus.
This error will loop endlessly several times per second until I restart the computer. In the meantime, nothing can access the drive and the OS struggles with the sleep/wake cycle. Usually, ejecting the disc will result in the OS succesfully unmounting the volume, but the eject signal is not reaching the drive, so the disc gets physically stuck in the drive until a restart. The drive functions normally at all other times.
Thinking the new drive was faulty, and following Applecare's suggestion, I replaced it with an identical unit, (actually the manufacture dates are only a month apart, September and October of 2008) but the problem still persists. At this point, I'm thinking that it's either a hardware compatibility problem or an incompatibility with the firmware version.
This is a fresh install of OS X Leopard 10.5.8 on a repartitioned and erased drive. All software is up to date. I have reset the PRAM.
This drive is (was) used in the newish iMacs, and obviously, the MacBook Air USB drive. Some googling shows that there are different firmware versions for this drive.
Anyone have any insight? Please? Help?
Here's the log entry from sleep to wake to the error:
8/24/09 7:53:17 PM kernel sleep

Anyone have any ideas? Anyone? If there's someone out there with a macbook pro using an internal optiarc drive, open system profiler and post your macbook pro model, what model number the drive is and what firmware the drive is running. Anyone? Please? (can you tell I'm desperate?)
aaron - was applecare of any assistance? It sounds like you've got a problem compounded by a vm. I can probaly help you out - I do mac IT work for a living. Does your IOATA error loop like mine does, or is it just a couple entries in the log?
To help narrow down the problem, shut down Windows and quit Fusion. Open console so you can watch the log. (make sure you aren't currently getting the IOATA error - if you are, restart) Then put your mac to sleep and wake it back up. See if you then get the looping error in the log. Whether the error is happening or not, make this behavior repeatable so you cna predict what's going to happen ie: restart, check log, sleep, wake several times so you know what's supposed to happen.
What we want to know is, does the error occur independently of Fusion, or only when fusion is running?

What settings do I need? As mentioned I used High Definition Tapes so I would like to have a high definition movie/dvd. Also after burning the dvd I suppose I can play that on any tv?? Please help with detail explanation!!
Thanks.

ITunes rejected my podcast - help with resubmitting

Hi there! First off I'd like to say that I have "minimal" expertise with podcasts, but have successfully been podcasting for a little over a year now. I'm a DJ and make podcasts of my DJ mixes for promotional use (like many of the 100s that are listed in the iTunes Music Store). I've tried a few times to list my podcast in the ITMS and every time it has been rejected with no specific reason stated (just the generic reasons given to everyone I'm sure). The ITMS did at one point have my podcast come up in it's search results but it never actually worked in allowing someone to subscribe to my podcast. I contacted the ITMS and they have since removed the search results.
I am trying to resubmit my podcast for approval and now I keep getting an error that the feed has already been submitted. I contacted the ITMS support team and they suggested the following:
"I also know that when podcasters receive a message that the feed has already been submitted, the iTunes Store is detecting that the podcast is a duplicate. You'll need to follow these steps to resubmit the podcast after making some changes:
1) Change the title and link fields of your RSS feed to something other than what they are now.
2) Resubmit the podcast feed via iTunes.
3) Once you have successfully submitted the podcast, you can change the title and link fields back to what they were."
I do not know anything about coding and/or XML and use a 3rd party application called Feeder to update my XML file.
Could someone PLEASE help me? I've been trying to get help with this for many months now, but kept posting under the GarageBand section. I'm thinking I'll get much more intelligent and applicable help over here.
My podcast is located at http://www.auralpleasuresmusic.com/. The Feed link is http://idisk.me.com/keith_bowden/Public/AuralPleasures.xml (which as you can tell by the URL I use my MobileMe account to host).
If there is any other information that will help with solving this please let me know and I will provide it.
Thank you!
Sincerely,
Keith

Your site is produced in iWeb and this will produce a podcast feed for you - perhaps that's how you are starting. The 'auralpleasures' text underneath the logo on your web page has a link to the same feed at feedburner.
The feed you give the URL for, on your iDisk, has, when downloaded, the filename AuralPleasures.xml.rss - you would do better to remove the .rss extension. However the feed can be subscribed to manually in iTunes. When examined in FeedValidator it says the feed is valid but comments 'Feeds should not be served with the "application/octet-stream" media type' - this may possibly arise from the double extension. However it's quite likely that this is not causing your problem
There is a bug in the iTunes Store whereby if a podcast is rejected and resubmitted it claims the podcast has already been submitted. In order to get round this you should change the name slightly - you could do this in iWeb and work on from there - for example call it 'Aural-Pleasures'. This would change both the title and the feed filename, and so would make it look like a new feed; then you should be able to resubmit it. I can't advise on how Feeder comes into this.
This leaves the matter of why your podcast was rejected. Reasons for removal include technical problems (probably not the case here), illegal or objectionable material (again, as far as I can see not the case either) or copyright violation.
The content of the episodes is 'mixes' and I would hazard a guess that the most likely explanation for your podcast's removal is that the iTunes Store is concerned that you are including copyright material for which you don't have either written permission from the copyright owner or a valid podcast licence from a recognized authority. If this is their concern, and you don't have such clearance, they are not likely to allow you to post your podcast (because under some jurisdictions they may be regarded as co-publishers and liable to the same civil suits as you might be).
If you do have clearance you need to make this clear to them, though I'm not sure how you can do this other than by contacting Support again, emphasizing the point, and hoping that they respond constructively.

I need your help with a decision to use iPhoto. I have been a PC user since the mid 1980’s and more recently have used ACDSee to manage my photo images and Photoshop to edit them. I have used ProShow Gold to create slideshows. I am comfortable with my own folder and file naming conventions. I currently have over 23,000 images of which around 60% are scans going back 75 years. Since I keep a copy of the originals, the storage requirements for over 46,000 images is huge. 180GB plus.
I now have a Macbook Pro and will add an iMac when the new models arrive. For my photos, I want to stay with Photoshop which also gives me the Bridge. The only obvious reason to use iPhoto is to take advantage of Faces and the link to iMovie to make slideshows. What am I missing and is using iPhoto worth the effort?
If I choose to use iPhoto, I am not certain whether I need to load the originals and the edited versions. I suspect that just the latter is sufficient. If I set PhotoShop as my external editor, I presume that iPhoto will keep track of all changes moving forward. However, over 23,000 images in iPhoto makes me twitchy and they are appear hidden within iPhoto. In the past, I have experienced syncing problems with, and database errors in, large databases. If I break up the images into a number of projects, I loose the value of Faces reaching back over time.
Some guidance and insight would be appreciated. I have a number of Faces questions which I will save for later.

Bridge and Photoshop is a common file-based management system. (Not sure why you'd have used ACDSEE as well as Bridge.) In any event, it's on the way out. You won't be using it in 5 years time.
Up to this the lack of processing power on your computer left no choice but to organise this way. But file based organisation is as sensible as organising a Shoe Warehouse based on the colour of the boxes. It's also ultimately data-destructive.
Modern systems are Database driven. Files are managed, Images imported, virtual versions, lossless processing and unlimited editing are the way forward.
For a Photographer Photoshop is overkill. It's an enormously powerful app, a staple of the Graphic Designers' trade. A Photographer uses maybe 15% to 20% of its capability.
Apps like iPhoto, Lightroom, Aperture are the way forward - for photographers. There's the 20% of Photoshop that shooters actually use, coupled with management and lossless processing. Pop over to the Aperture or Lightroom forums (on the Adobe site) and one comment shows up over and over again... "Since I started using Aperture/ Lightroom I hardly ever use Photoshop any more..." and if there is a job that these apps can do, then the (much) cheaper Elements will do it.
The change is not easy though, especially if you have a long-standing and well thought out filing system of your own. The first thing I would strongly advise is that you experiment before making any decisions. So I would create a Library, import 300 or 400 shots and play. You might as well do this in iPhoto to begin with - though if you’re a serious hobbyist or a Pro then you'll find yourself looking further afield pretty soon. iPhoto is good for the family snapper, taking shots at birthdays and sharing them with friends and family.
Next: If you're going to successfully use these apps you need to make a leap: Your files are not your Photos.
The illustration I use is as follows: In my iTunes Library I have a file called 'Let_it_Be_The_Beatles.mp3'. So what is that, exactly? It's not the song. The Beatles never wrote an mp3. They wrote a tune and lyrics. They recorded it and a copy of that recording is stored in the mp3 file. So the file is just a container for the recording. That container is designed in a specific way attuned to the characteristics and requirements of the data. Hence, mp3.
Similarly, that Jpeg is not your photo, it's a container designed to hold that kind of data. iPhoto is all about the data and not about the container. So, regardless of where you choose to store the file, iPhoto will manage the photo, edit the photo, add metadata to the Photo but never touch the file. If you choose to export - unless you specifically choose to export the original - iPhoto will export the Photo into a new container - a new file containing the photo.
When you process an image in iPhoto the file is never touched, instead your decisions are recorded in the database. When you view the image then the Master is presented with these decisions applied to it. That's why it's lossless. You can also have multiple versions and waste no disk space because they are all just listings in the database.
These apps replace the Finder (File Browser) for managing your Photos. They become the Go-To app for anything to do with your photos. They replace Bridge too as they become a front-end for Photoshop.
So, want to use a photo for something - Export it. Choose the format, size and quality you want and there it is. If you're emailing, uploading to websites then these apps have a "good enough for most things" version called the Preview - this will be missing some metadata.
So it's a big change from a file-based to Photo-based management, from editing files to processing Photos and it's worth thinking it through before you decide.

Any Photo editing tips to help with my wildlife photo contest entry?
