Scanned slide resolution

I would like to create a calendar or book using images that I will scan from slides or pictures. At what resolution should I scan these so that I don't get the low resolution warning. I have experimented with various settings, but iPhoto 6 doesn't seem to like anything that I do.
Thanks.

If disk space is an issue - buy a new hard drive! You really need to be scanning at your highest resolution possible, and at the largest size possible (without interpolation), and saving as either tiff or eps file format - not jpeg.
On a Mac (maybe PC?), you can save tiffs with LZW compression, which is completely lossless, and can be saved as many times as you like, without further loss, unlike jpeg, which loses a bit of information every single time you re-save. However, LZW is not always compatible with other systems, though. Jpeg, of course, has its place, but saving it many times eventually results in poor quality images.
The key thing is, those large size images are your master images. Create a duplicate of these, and then crop resize, colour balance, sharpen etc etc to your hearts content, safe in the knowledge that you have that nice clean original, should things go wrong, or different projects comes up.

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!
Tony

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.

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.

Premiere Elements 12.1 and Scanned Slides

I have 370 JPEG scanned slides that I want to make into a video. Each slide will run for 5 seconds for a total of 30 minutes. I have a Dell desktop with 8 gigabytes of RAM and a 7200 speed hard drive. The computer has an Intel 1.5 processor. Can Premiere Elements handle this amount of slides?

Michael Stehly
Yes, on handle that number of slides, but......
What are the pixel dimensions of these 370 JPEG scanned slides and what is the destination for them?
If you are using Premiere Elements 12/12.1 on Windows 7, 8, or 8.1 64 bit, you can get away with higher pixel dimensions that would be indicated by
the classical recommendations that you may see for "not to exceed 1000 x 750" et al.
The answer goes to computer resources, pixel dimensions of the photos, and the number of photos. No matter how high the resolution of the photos, the export will be forced to the specifications of the export format selected. You need to define your fine line between letting the program do the resizing and that process slowing down or stopping that process.

Scanning Slides

It's hard to decide which approach to take when scanning slides -- I was
recently confronted with that when I decided to digitize 35 years worth of
family and vacation slides. I learned some important things I never see
covered in these forums.
1) Just do it. Now
I discovered that my oldest slides are suffering mold damage. Sure, there
are cleaners (including 50-50 denatured alchohol and water) that will clean
them but they won't restore digested emulsion.
2) The Perfect is the enemy of the Good.
I'm happy with a flatbed Epson 4870 at less than its rated resolution (2400
is my "sweet spot" of quality, file size and scan time). 8 Slides at a time
and the Epson default driver gives me a histogram control (like the Elements
"Levels") right off the preview image.
You can always go back on a cherished few slides and do a "better" job later
or send to a lab.
3) It's all about workflow.
The biggest pain is just sorting through and dusting scads of slides - keep
the photography part simple and mechanical so you can devote your energy to
decison making. Give yourself some stress free time when you start out.,
After you establish a good workflow, it becomes very easy.
4) Yes to Digital Ice -- I still dust the image and the bed every time but
the Digital Ice covers my mistakes (and the dust that flys on between the
brush and the scan...)
5) This task plays to Organizer's strengths. Do some simple tagging as you
roll along -- trip name, year things that mean something to the content.
But also consider leaving yourself some help in finding the original
later -- each slide has a "month - year" stamp from the lab, I create a tag
for each such stamp and that should help me find the original in future
years should I care to do it. It also is a backup for any date and time
settings I make in organizer later.
(But don't trust organizer completely -- I also create directories whose
name matches the lab tags as the destination for each batch of slides. Belt
and Suspenders.)

I'm happy with the results of my "8 slides at a time" Epson 4870. I could have chosen 4800 resolution, but I found it looked too grainy compared to 2400. I can do 100 on a Saturday as I do other chores and activities. Perfect is the enemy of good.

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)

Difficulty scanning slides on my Epson V600 running Lion, Adobe Photoshop CS6, and can no longer use the Epson scan application or the plug in for Photoshop. Should I revert back to leopard in my time machine to finish scanning my family slides?

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.

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?

Choice of Slide Resolution

Having read the HELP Topic with Keynote 08 on Slide Resolution I feel that there's important detail missing. ANYONE OUT THERE WHO CAN HELP BEFORE I CREATE LOTS OF SLIDES??
1) Since (I've noticed) that if I decide to change the slide size of a presentation I'm going to have to rework each slide manually, it seems super important to get it right before finalising a big presentation.
2) Since people with MacBook Pros may travel and encounter a variety of venues (and projectors) it seems super important to take this into account before preparing a presentation.
From the information given it's not clear whether.
a) Its best to choose a large resolution for the slides (at least as great as the highest resolution that you think you may ever encounter) and let Keynote Scale down automatically for smaller displays??? Are there disadvantages to this???
b) It's better to choose a more average resolution and then have Keynote Scale up?? I understand there may be some pixellation but if that's a bad thing depends on your answer to (a).
c) you say that if I want to integrate a movie I may want to choose a higher resolution... Why??? (Isn't the projector the limiting factor?) What are the consequences for the rest of the presentation?
Thanks

thanks everyone - this is all very helpful....
Yes, basically like most people I use 1024 format. HOWEVER there are one or two places with big theatres where I may encounter HD. Also, talking to fewer people, I might be tempted to use my 23 inch Cinema Display (which is basically HD too). Hence the interest in getting it right first time.
If it's better to build big and then scale down then I'd certainly be tempted to take that route. However that might mean building slides that then don't look good when displayed with less pixels. A matter of discipline, I guess, to keep them simple and not too crowded.
Unbelievably, it hadn't occurred to me that some of the slides might be of different proportions!!
Indeed it's complex because no perhaps there is not a single answer. So I appreciate all of your comments and collective experience.
Thankyou!

Slide resolution?

Will Keynote allow a custom panoramic slide resolution setting of 3840x960? Also, can you import into Keynote morphed images from Morph Age?

Keynote will indeed allow that custom size.

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.

Captivate 8 (C8) not transferring correct slide resolution from PowerPoint (PPT)

I am tasked with transferring quite a number of PPT presentations into C8. I have come across a few 'bugs' and am trying to solve them, one by one.
Today's issue: slides from PPT are not transfering into C8 with the correct screen resolution. The first thing I noticed about my slide transfer was that the titles in my PPT slides are not in the same position when transfered over into C8, and the font is pixilated. Even when I go into PPT and make changes, save those changes and then update the file in C8, I still have a problem with the titles not being in the correct spot. I know they are off because the titles appear within a band of silver, with a thick, brown bar above them in PPT. In C8, the titles are squished into the brown bar with too much space left over in the silver band -
The title and bands in PPT:
The title and bands in C8:
This is using the default 10" x 7.5" aspect ratio in PPT, and the pixel equivalent in C8 of 720x540. The font is BANK GOTHIC.
(BTW: I found a chart here - I Came, I Saw, I Learned...: PowerPoint: Changing Slide Sizes for Importing into Captivate which is not correct. For instance, this chart suggests a slide resolution of 10.5" x 7" would transfer over into C8 as1008 px x 672px. This size is incorrect; it still produces incorrect slide resolution. And there is no way to use this chart for custom slide sizes).
When I changed the font (to CENTURY GOTHIC), I did get a better result in the position of my title:
PPT new font:
C8 new font:
However, I am still experiencing the pixilation of the font. I closed this project out of C8 without saving and then re-transfered the files. This time, I went with the C8 default resolution of 960x720 - this translates in Powerpoint to 13.333" x 10". NOT the same slide setting I have in PPT, which is 10" x 7.5" however, this looks much better, with less pixilation of the font within the work area. When I publish it out, the pixilation goes away and the font is smooth again.
My conclusion: some fonts do not transfer well into C8, and screen resolutions differ from PPT, Photoshop and C8. If you are having difficulties getting your PPT slides to look the same in C8, it could be your font is not transfering well, or it could be your screen resolution.

Not really an answer, but the big problem IMO is that PPT, although a presentation tool that will use screens (or projection systems) defines a project in printing units (inches or cm) which is totally crazy. Captivate is a bit more normal for that aspect, it uses pixels to define the size. And screens, devices no longer have all 72ppi. Sorry for the ranting...already commented that way when PPT first appeared (used better applications like Freelance Graphics for presentation, they are now killed by PPT). Contrary to Adobe, MS never listens to comments, reported several bugs in MS Project as well, they are still present in the latest version 15years later.

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.
