Cropping a scanned slide automatically

Does Photoshop have the facility to crop a scanned slide automatically? When I scan, I make the scan selection in the scanner a fair bit larger than the slide to accommodate all slides. i.e. if I'm scanning a number of slides they can end up in slightly different positions in the scanner. So as not to have to adjust the scan selection each time, I make it larger than required. Then I have to remove the black that surrounds the slide in PS.
I can do it manually a number of ways. The easiest appears to be to set up a template selection and move it around for each slide. But that takes time. So I'm hoping PS, or other software, can analyse an image of a slide and, knowing that there are four straight sides involved in a slide, accurately crop to the sides. Even better if it could crop to the rounded corners of older slide mounts.
One difficulty will be when the slide itself has dense black on the edges that may be confused with the black of the slide surround. That's why I mentioned straight edges. The software I'm hoping for would know that four straight edges are expected and somehow it would dismiss any dense blacks close to the edge of the slide.

Have you tried File > Automate > Crop and Straighten Photos?

Optimum workflow for creating an audio-visual from scanned slides?

I'd like some suggestions as to the best workflow to adopt when generating an AV from scanned slides. I'm transferring my 3-screen audio-visuals from slide format to Blu-ray. The slides are being scanned on a Nikon Coolscan, and after editing end up as ~100 MB, 5400 x 3700, Tiff files with seven layers. These files are then archived, separate from anything I do with them in Premiere. They'll be imported into Premiere, along with the original soundtrack, and eventually output to Blu-ray disk. Then I hire the local cinema for an evening or two, let the word spread, and we reminisce and party!
I realise that pre-conditioning the images – flattening, cropping, down-sampling to a suitable size – would be a good approach, but I'd rather avoid that if possible for two reasons: (1) so that I only have one image to keep track of, instead of the original and a Premiere version; and (2) if I decide to edit colour or contrast I can do so non-destructively on the original. The latter is an important consideration. Images may be used in more than one project. If I decide to alter the look of an image (not because of the look of the image within a particular project, but because I decide the original edit was inherently flawed), it would be better to alter the original and have that change reflected in all other uses of the image, than to alter, say, two copies of the image plus the original.
A finished AV will range from 30-400 images. The longer shows will be broken into sequences of no longer than about 20-30 images. These are some of my concerns:
Cropping
The scanned images include a small amount of the slide mount. That way I know I've scanned the entire slide. So that has to go. And given that slides are 3:2 and Blu-ray is 16:9, something else has to go as well. I've been through most of the Premiere PDF but have yet to come across a cropping tool. I know how to position, scale, rotate, but how do I crop? Scaling is not a substitute because I may want certain images to not fill the screen and not show the slide mount.
Flattening
Will layered Tiff files cause difficulties in Premiere or Encore?
Resolution
Will 5400 x 3700 files (versus resampling to 1920 x 1080) have a serious impact on the time in takes for any part of the process from importing into Premiere to encoding in Encore?
Image Order
Is it better to order and renumber images using Adobe Bridge, or should I just shuffle images around in Premiere? Working with Premiere alone would have the advantage that I can import the originals (if that is an acceptable workflow).
Packaging
When a project is finished, I want to package all the assets via Project Manager and archive them. And I'd rather not archive 100MB image files. Now, this is going to be a big ask, and I'll have to jump across to InDesign to explain. When I've used scanned images in InDesign, I link to the original 100 MB files. No problems whatsoever. Come archiving time, I package in one of two ways: use an InDesign script to crop and resample the original images, and then package; or I simply export to PDF, and during the export all images are automatically cropped, resampled, and saved within the PDF in whatever format I choose. A simple and elegant archive.
Does Premiere have the ability to crop and resample the stills it uses, and either overwrite the original or save as a new file?
That question has just made me think: if I do need to crop, flatten and resample before importing into Premiere, or for archiving, maybe I should be mocking up my Premiere projects in InDesign set to a page size of 1920 x 1080. I could drag in all the images, then shuffle, crop and size them. When I'm happy with the sequence, I export as jpegs, and get the cropped, resampled images that way, ready for Premiere.
Any comments most appreciated.

Your last paragraph makes the most sense. Although a script in Photoshop would easily do what you want.
Before you resize them, make sure you don't really need to pan across them. Resizing down to around 4K or so might avoid problems.

What resolution & order of work to scan slides for Photoshop editing

When editing all done I would propose to save at 300 dpi. If the photo/slide requires no editing, I would also scan in and save at 300 dpi.
My slides, however, need a lot of work. They have deteriorated over the years and need - colour correction, removal of colour casts, brighten up shadows, brighten up colours etc. etc.
I have read many books and tips but they all seem to think I want to produce prize winning images with amazing time consuming enhancements! I just want, as I have seen from other threads, to get into a simple routine and crack on through the pile of slides to produce acceptable digital images!
My simple mind suggests give Photoshop as much to work with as possible!
I have:
- a Minolta Dual 3 AF 2840 Slide scanner which has many features akin to Photoshop - curves, Levels etc.
- Photoshop 6.0.1 and Elements 2.0 - not very up to date I am afraid!
Three questions:
1) The maximum Scanner resolution is 2840 - I would have thought scanning at this best to get the most information of the image into Photoshop. Would this seem right - I can resample down to 300 dpi at the end?
2) How much editing should I do in the Scanner - to give Photoshop the best information to work with - e.g. should I use Levels/Curves in the scanner to brighten up the shadows for Photoshop etc?
3) Once in Photoshop for final editing, what is the best order of work and which tools best to use, bearing in mind for, say colour cast, you can use Curves, Levels, Colour Balance, Variations etc, etc.- it seems colour balance is best for this from what I have read. My suggested routine is:
Use Scanner to scan and do initial editing:.
- Clean slide
- Crop
- Set 2840 Resolution
- Pixel polishing etc
- Use Colour balance for colour cast
- Curves/levels to bring out detail from the shadows
- Scan
- Save as TIFF
Photoshop
- Crop
- Final Overall Tonal adjustments - Curves and Levels?
- Final Overall Colour casts - Colour Balance?
- Adjust specific tonal adjustments etc. for selected areas - Dodge, Burn etc?
- Other adjustments - Clone out blemishes etc.
- Unsharpen
- Resample to 300 dpi and save as JPG or TIFF etc. for required purpose - usually JPEG
Does this sound right - any suggestion for variation etc. will be most welcome?
Any other advice also most welcome!

Dear Marian,
Thanks for the prompt reply - it sounds like it is just what I want to hear!
Just to double check my understanding! Do you agree, then, that it is a good idea to scan slides (and negatives for that matter) at the maximum resolution for the purpose of further editing in Photoshop?
As you say, Photoshop will reduce the ppi automatically for larger images than the slide. Most of my final printed output will be 6x4" but it still gives me scope for a half decent print at 8x11" if I want.
As I understand it, Slides and Negatives are pretty dense and can accept high resolution scanning whereas to scan a magazine page, for example, there would be no need to scan at more than 300 dpi - in fact to do so may even produce funny results!
I know people can get carried away with resolution. I do get amused when people get excited about their super megapixel cameras when they ever only display the results on a screen or a small print!
Thanks again for your comments - if you can confirm the above, that will be one big issue solved for me.

Auto-Cropping gang-scanned photos! HELP

I need help figuring out how to correctly divide scanned photos automaticly. Photoshop Elements 10 had a preset to do this but everytime we go to use it, it crops them wrong. This is the sole reason we purchased Photoshop Elements 10. It's cropping right down the center of the photos. Can someone please help, we've been working on this for days! Thanks

Try putting the photos more crooked on the scanner bed, and if they're very faded and pale, try putting a contrasting background behind them before you scan them. Also try a different arrangement. Something is preventing PSE from seing the edges properly.
Incidentally, many scanner drivers have the ability to do this these days, sometimes better than PSE can. If you strike out again with PSE, see if the scanner can do it for you.

Correcting colour and contrast in scanned slides

I am investigating how to scan slides as accurately as possible, with the qualification that sometimes I may accept less than 100% accuracy for a better-looking image. I am in the midst of comparing several scanning methods, and at this stage one particular method stands above all the rest.
My original idea (before I started testing) was that I would not ask the scanner to do much processing of the raw image, that I would edit in Photoshop. The reasoning was: there's no better image-editing program than PS, and if PS (or its plugins) can't improve the image no other software could.
Well, it looks like I was wrong. I have tried to edit several raw scans, and using PS I can't get results that are as good as asking the scanner to edit the slides.
I have uploaded two sample scans to: http://www.mediafire.com/?z1w4ekew39dwa
Each scan has two versions: a "natural" scan out of the scanner (no corrections), and a corrected scan (suffix GB) using various scanner settings.
What intrigues me is that the scanner is able to automatically correct colour casts and improve contrast across a wide variety of slides. i.e. I have tested slides from the 1960s through to 2007 on various stock (Fuji, Anscochrome, Kodachrome, Ilfochrome). In almost all cases, and without changing the scan settings, images come up as good as the two uploaded images. The only setting I sometimes need to alter is what I call the "gamma", for slides that are underexposed or have a lot of dark regions where detail should be visible (and the reverse for overexposed slides).
Maybe I am not using PS to its full potential, so I am hoping that someone can have a go at editing the "natural" scans to see how close they can get to the corrected scans from the scanner – and then explain how they did it.
I am astounded at what the software inside this scanner can do with images. I thought PS was the be-all and end-all for images, but in my hands, PS comes in second and I'd like to know how to improve its performance.
Thanks in advance for any input.
Notes
1. I purposely choose challenging slides for testing. They either have a large contrast range with visible detail in the highlights and shadows; or colour casts; or bright saturated colours.
2. When testing, I compare all scanned images as seen on my computer screen with the original slide on a hand-held light box viewed through a loupe. For example, all colours in the image called Slide Scan 15 GB, even the metallic-looking sheen of the raincoats, appear as a close match to the original slide. The only significant colour variation is in the foreground rocks (which are a grey-brown colour in the slide), and the sky (which is a slightly darker blue in the slide). This slide is, maybe, 1/2 stop underexposed which explains the saturated colours and the dark "natural" scan.
3. The scanner spends a significant amount of time applying corrections. An 18 MB image (2000 dpi) might take 30 seconds to scan, then another minute for the corrections to be applied.

Get error message when trying to scan slides

HP Scanjet G4050. Latest drivers. Now up to 10.6.8 and when I try to scan slides or negatives, I get an error message: "Remove any objects from the scanner glass. Load your slides and negatives. Try scanning again."
I have scanned in the past. Is this a problem with 10.6.8? I have heard of printing problems with it. Should I revert to an earlier version of the OS?

Make sure your lid is pushed all the way down. I had the same problem, then I noticed a gap between the lid and base near the hinges. I opened the lid fully, pulled it out (straight up) then pushed it back down firmly. Works fine now. (Using OS X 10.7 with update from HP)

I am running Lion 10.7.5, Adobe Photoshop CS6, scanning slides on my Epson V600 and can no longer use the scan application or the plug in for Photoshop. Should I revert back to leopard in my time machine to finish scanning my family slides?
In 10.7 there is not a twain that works with Photoshop for importing with all the options needed to scan transparencies. I noticed that when I was scanning in October 2012 I was still using CS6 so somehow I was managing to be able to use all the scan features.
They sell 2nd party software (VieScan and Silverscript)which I found to be just mimially OK and very hard to use.
I just want to scan like I used to.
Can I use time machine to go back to an earlier operating sysytem LEOPARD, and then do my scans and then save the photos and them go back to the LION system?
I spent 7 hours trying crazy solutions - downloading Windows CS2 Photoshop and then using a program so I could run it on the apple. Then I couldn't figure out how to put a plug in for the scanner in the stupid windows Photoshop program. Googgling the computer like a mad woman trying to ask questions. I am not giving up...
Please help if you can...
Thanks...

I assume you've tried using Image Capture. Give VueScan a try.

Scan slides on Canoscan 8800F/Mac OS 10.8.5

I am not a techie and would like advice on scanning slides with Canoscan 8800F, Mac OS10.8.5. I have been told this can be done in Preview but there doesn't seem to be a slide option and the slide shows up as opaque black, likewise don't see any slide option in Image Capture. Have downloaded MP Navigator EX but get list of supported models which does not include 8800F and need to install correspondent MP Navigator or MP Navigator EX and driver/scanner driver which supports my product model (have already downloaded driver which is supposedly correct). I'm very confused, will probably go for Vuescan option, but welcome any advice. (And why isn't there a scanner section in this forum?)

How do I enlarge a scanned slide in iPhoto? It scanned fine but appears quite small in the middle of the page, surrounded by black.

How do I enlarge a scanned slide that I have imported to iPhoto? My Epson printer scanned it fine but I would like to make it larger, instead of having it appear small and in the middle of the screen, surrounded by black.

Zoom into it. There's a slider at the bottom of the iPhoto Window.
Next time, try scanning to a larger size.

Can I make the slide automatically move on the the next page?

Like I have media on a keynote presentation and 3 seconds after it finishes I want it to move on to the next slide automatically. Is this possible?
Cheers.

No one can help???

Can I unpause a question slide automatically?

Once a question slide enters the pause state, waiting for the button to be pressed to move on, can I make it advance to the next slide automatically if the user does nothing for say 5 seconds?
Thanks

Thanks Lilybiri, I think custom slides will help me and your blog is very useful.
The real reason I want timed slides is that I'm trying to make a quiz which will syncronise to a DVD playing on another device. The idea is to start the DVD playing and start the Captiv8 quiz at exactly the same time. The video will then play (it can't be skipped or paused) and contains 5 questions over 5 minutes. I need question 1 to appear at exactly 1 minute in, question 2 to appear at 2 mins in, and so on for all five questions. The problem is that these question slides need to appear at the right time, every time, no matter if a user has answered a question, pressed something, changed their mind, done nothing at all , or had several attempts or whatever, without changing the total length of the quiz which will always be exactly the same length as the video on the DVD whatever the user does.
I really need a kind of 'master clock', perhaps on a master slide (?), which will force the Captv8 to turn to the right question at the right time, no matter how long the users take to answer, or even if they do nothing and ignore a question completely. I would like to add a countdown timer on each question too, so they know how long they have to answer before the slide disappears and moves on automatically. It's a high pressure quiz, as you have written about in the timer blog you wrote, but where the Captiv8 quiz won't alter its overall length whatever happens. Obviously I need to give them a score at the end.
Hope you have some suggestions!
Thanks again.

Can I create slides automatically using a master slide with text placeholders if I have a database of the content?

I'm using Keynote, and I have a presentation that is over 100 slides all identical to the master slide. There are several placeholder text elements, and I have a database of all the text elements.
Is there any way to do a "merge" to create the slides automatically using the master slide template?

Sure, you can build in and out as many text boxes as you like -- just add a new text box, put in the text, and set the build for it. Do be aware, however, that the timing you get will not be very precise.
If you specifically want to present song lyrics synched to audio, you might find that there are better alternatives than Keynote. Brian Peat, who contributes here regularly, has a comprehensive list of song presentation software. This list may have a better option for you.

Watervrees
Your details are unclear to me regarding the involvement of Premiere Elements (any version) in your question of
"How do I scan slides."
I am not sure if your are
a. In Elements Organizer of Photoshop Elements 12
b. In Elements Organizer of Premiere Elements 12
c. In Photoshop Elements 12 Full Editor
You can scan into the Elements Organizer 12 mentioned above (a or b)
File Menu
Get Photos and Videos
Scanner
and the resulting formats will depend on the specification of your scanner (I can get jpeg, tiff, or png)
You can scan into the Photoshop Elements 12 Full Editor
File Menu
Import
and then look for the name of your scanner.
Before you do the above....
a. Go To
Local Disk C
Program Files (x86)
Adobe
Photoshop Elements 12
Optional Plug-Ins
Import-Export
and make a copy of "Twain_32.8BA" that is in the Import-Export Folder. Do not remove this file, just make a copy.
then
b. Go to
Local Disk C
Program Files (x86)
Adobe
Photoshop Elements 12
Plug-Ins
and paste the "Twain_32.8BA" inside the Plug-Ins Folder (you want the "Twain_32.8BA" as a file in the Plug-ins Folder. Do not put it into a folder inside the Plug-Ins Folder.
then determine if a. b. c recognize your scanner. It may not be. Then you will have to scan to the computer hard drive and then import from the computer hard drive into your applications.
Please let us know the outcome.
The above works for scanning photos. Other depends on the specifications of your scanner.
