Correcting and cropping scanned images as a batch

I am working on a project involving about 20,000 scans from historic journals. We are trying to create replicas, since the originals have not been preserved.
The scans have already been completed and my job is to figure out how to get the actual block of text, which is about 4.3"x7.3", to be centered, both horizontally and vertically. Then the pages will be printed and trimmed down to the 6x9 page. The scan job wasn't extremely precise, since the margins aren't uniform.
I'm wondering if you have any ideas about how to do this job in a batch fashion. The files are in TIF format.
I appreciate any suggestions/advice.
Sincerely,
Tricia Dameron

Looks like you're not getting much feedback on this challenge....
If it was mine, and I was the person actually doing it, I would optimistically quote about 80 hours to place and align manually, one by one. Pity the scanners weren't thinking ahead!
The reason I say I estimate on my own rate is that you could give this task to several different people and get very different ideas of how to do it and if you assign to the wrong operator you will end up well out of pocket.
Some tasks just can't be automated, maybe someone really clever can do it with your job but probably not economical, I would just sit down for a fortnight and do it!

Adobe PSE 8.0 - "crop scanned images"

Hiho!
I've bought PSE 8.0 to rework allready scanned Tiffs. Each Tiff includes 3 - 5 (almost aligned) images. Now I found the menu item "crop scanned images" (or how its named; I've a german version). But when I select this menu item PSE begins to preform something wich results in a 1:1 copy of the original TIFF. I guess thats not the result I've to expect. I tested a few other TIFFs too but the result is always the same.
The Tiffs are really nothing special. White background with colored photos. Hm, do I have to preform some adjustments before to prepare this action? I'm really confused.
Regards

The fact that your photo's are "almost aligned" may be what's causing the problem.
The Cropped Scanned Photos feature is designed to take a scan of multiple photos and separate them out into individual photos. If your photos are already well aligned, and seem to blend together, then the algorithm is likely having trouble picking them apart.
You may need to crop them out manually.
If you post one here, I'd be happy to take a look at it and offer some better (hopefully) advice.

Scale and Crop with Image Alchemy

Hello,
We're using Digital Asset Managment with Image Alchemy for the conversion engine. Does anybody know how to configure a rendition set that scales and crops an image without distortion? So if you check-in a 1000x1500 pixel jpeg, it could scale it down and crop it to exactly 100x100 pixels.
I've been looking through the Image Alchemy documentation, but haven't found this example yet.
Thanks
-Jason

All you need to do is define an "ImageAlchemy" variable inside the "ImageManager_NameValues" ResultSet, DAM automatically knows when to use it for the rendition info. But instead of pointing to the ImageAlchemy executable file, I point to my script. For my conversion ResultSet's extEngine, I refer to an "ImageMagick" variable instead.

Lens Correction and Cropped Pixels

I'm starting out as an architectural photographer, and as I don't yet have a perspective correcting lens to adjust images in-camera, I need to use the Lens Correction tools in Photoshop and ACR. I prefer to use them over the Free Transform tool for the sake of accuracy (and convenience), but I do have an issue with the tools. When I correct the perspective of an image and then process, whatever extends beyond the boundary of the canvas winds up being automatically deleted, and it seems as if there's no setting to prevent this from happening. As there is sometimes a piece of a photo that I would like to be able to retain (i.e. extra sky, the top of a building, etc.), I understand that I can scale down the image in the Lens Correction tool and then re-crop after processing. Of course then this causes the image to still be smaller than I would like it to be (in certain cases where the distortion correction is more extreme, an original 21MP photo might become a 12 or 13MP photo after processing in the Lens Correction due to scale-down).
Is there any way that the Lens Correction tool will allow for pixels extending beyond the boundaries of the canvas to remain uncropped, thus allowing me to expand the canvas in order to reclaim the extra information?

Yammer P, yes the list is shorter because it's a jpeg rather than raw, and we have more profiles for raw than for jpeg.
For the set of lenses supported in CS5's initial release, we created profiles for both raw and jpeg. Since then, we have been concentrating on raw-based lens profiles, for a number of reasons (one of which is that we feel we can consistently deliver the highest quality results this way). This is why you see some lenses supported with raw & jpeg profiles, but many more supported with raw only.
CS5's Lens Correction plug-in does indeed let you choose raw-based lens profiles even though it is processing a rendered file (e.g., jpeg, tiff). This will work in many (but not all) cases for distortion correction, but will often work poorly for chromatic aberration and vignette correction. I don't recommend this workflow and it is a key reason we don't let users mix/match in ACR & LR.

Auto crop Scanned Images w/black edge? 1500+ photos to crop!

I have a job where the client scanned over 1500 photos but didn't crop them properly so there's random black bars & edges everywhere that I'm required to get rid of. Is there any way for Photoshop or ANY application to auto detect and crop & save a batch of photos? This would save me a TON of work. Any suggestions would be greatly appreciated.
I'm currently running Mac OS X Leopard10.5.5, CS3 production suite, Aperature, iPhoto and more

>Wouldn't that make cropping unpredictable?
Only if the complete edge of a pic has the same values (and then really isn't it part of the edge? ;) ). Crop works on the bounds, so pixels inside don't matter. I think to really answer the post, we need a better idea of what these edges are. 0,0,0 generated by cropping as a bg color? Scanned rich black complete with detectable kicker rosette? Tranny black?

How do I smooth black and white scanned image?

I am trying to edit some scanned images that appear to be printed on linen with the pixels showing. I scanned them at the highest quality possible but that didn't help. So, I tried editing using the blur feature. Not only is that quite time consuming but I fear I am losing some of the quality of the image by doing it this way. Where do I begin and what steps do I follow to take out the checkered effect?

Rotating and cropping an image.

I am taking a Photoshop for school and we are using CS5. I have CS6 and I'm stuck on my picture rotating back straight when I am trying to crop it. I use the rotate view and rotate it 6degrees. As soon as I hit the crop button the picture goes straight. How can I keep my picture rotated to the 6degrees and crop it without the perspective crop tool?

Rotate view only rotates... the view; not the actual picture. It's temporary and non-destructive. It's used to help move the canvas to a better angle for drawing brush strokes.
You want to actually rotate the image or canvas. Either Ctrl T for Free Transform and rotate by moving the cursor outside one of the corners and dragging. Or Edit > Transform > Rotate

Automatically zoom and crop an image to fit in a square

I've got an mx:Image which is loading an image from the web. I don't know how big the image will be in advance. I'd like the loaded image to fit within the mx:Image's square frame by zooming and cropping off the sides or top/bottom as needed. In other words, if the image frame is 64x64 and the loaded image is 70x64, it will be centered and lose a few pixels on the right and left sides. Is it possible to do automatically? I've played with maintainAspectRatio and scaleContent but I haven't been able to get what I want.

In an ideal world we would use a high resolution version with a 100% width set for every device (and screen size). Because of bandwidth reasons, the page should load only a version of the image intended for a specific width range.
Sometime in the future we will (probably) be able to use this:
<picture width="500" height="500">
 <source media="(min-width: 45em)" src="large.jpg">
 <source media="(min-width: 18em)" src="med.jpg">
 <source src="small.jpg">
 <img src="small.jpg" alt="">
 Accessible text
</picture>
However, this will not yet work. Therefore, ideally, a polyfill picturefill method that works quite well can alternatively be used:
https://github.com/scottjehl/picturefill
Solution:
Call the picturefill.js (see above url for more information and sample code)
body:

 
 
 
 
 
 <noscript>
 <img src="external/imgs/small.jpg" alt="A giant stone face at The Bayon temple in Angkor Thom, Cambodia">
 </noscript>
 
This works in all browsers and devices. On a mobile platform only the lower resolution image will be loaded up.

Straightening and cropping scanned photos...is there a trick for this?

Hi,
I am scanning a bunch of photos of various sizes/shapes. If I place the photos right up against the edge of the scanner, it crops it. So what I have been doing is eyeballing it a couple of centimeters away from the edge. Naturally it is slightly off as far as being aligned straightly. I have been using transform to adjust the photo so it is straight. Is there any trick within Photoshop to align it according to the images edges?
Also, is there any way to use the wand (to basically select all of a photo) and then crop the selected?
Thanks!
PS. Since the photos are of various sizes I cannot use a holder.

If the scanner is cropping the very edge of the glass off, try putting a piece of white tape down on the glass - maybe a 1/2 inch wide strip exactly parallel to the scanner edge. You can then slide your prints up to that and they will be aligned and within the scannable area.
There are a couple of ways to easily deal with your current crop (pun intended) of scans. The easiest way is to just use the Crop Tool to both crop and rotate at the same time, but make sure that you leave the resolution blank in the crop tool options at the top. The second is to use the Ruler Tool to measure along any of the sides of your scan. That angle will be recorded automatically in the Image>Rotate>Arbitrary dialog, where you can rotate the image back square again. You'll then have to crop it, so you might as well just do it in one fell swoop with the crop tool.

Using photoshop elements 13 but the option to crop a single image is grayed out and also the option to crop a scanned image into individual pictures is grayed out - any ideas?

The option to crop an image is always grayed out or unavailable - both for single images and when I want to crop scanned images into individual pictures. Any idea what I may be doing wrong?

Did you try using the crop tool to see if it is working? See the tool I am talking about.
I suspect you are in Guided Mode rather than in Quick Mode or Expert Mode.

How can I divide my Aperture Library between digital and scanned images?

I am scanning 20,000 35mm slides to my Aperture Library. I have started importing them as TIFF files because the resolution of the JPEG files is not as good. Because of the number and size of the images, I would like to "split" my Aperture Library so that my current digital images are on the iMac HD and the scanned images are on a dedicated external HD. Is it possible to do this? If so, how do I set it up? Will the scanned images be managed or referenced images?

"Scan" means "digitize". Once your media is scanned, it is digital. Your question then becomes "How can I group my scans?" and "Can I store the Originals of the Images based on the scans externally?".
There are many ways to group Images. All of them are based on either giving the Images you want to group some unique marker, or using a marker that is already unique to them as a group. How you do this is up to you. Options include but are not limited to: put them in Projects and put those Projects in a Folder called "Scans", keyword them on import as "ScannedFrom35mmSlides", name them when scanned with a prefix such as "Scand35mm_", etc.
Aperture allows you to store the Original of each Image wherever you want. Storage devices mounted directly to your computer are recommended. Aperture provides tools to move each Image's Original inside your Library package (the Library package shows in Finder as a single file with the file extension ".aplibrary"), to relocate it outside your Library package at any location you specify, or to relocate files which are currently outside your Library package wherever you want.
Originals inside your Library are called "managed". Originals outside your Library are called "referenced". This is a per-Image setting, though moving these files is almost always done in batch, and most people keep their Library with every Image's Original either managed or referenced.
Having a "mixed Library", with some Image's Originals managed and others referenced, presents no problems.
The commands for relocated the Originals of the currently selected Images are on the "File" menu. Directions on using these commands are in the User Manual here.
Here is a concise guide to the parts of Aperture. Should any of the above be confounding, it may help clear things up.
I suggest determining the naming conventions, storage, and keywording that you are going to use in Aperture before you proceed. Rigorously building well-designed storage and retrieval structures from the start will make your image database easier to use, and more useful, than making changes ad hoc along the way.
Fwiw, JPG and TIFF are not differentiated by resolution (which is the pixel dimensions). TIFF is recommended because by default it is not compressed (no data is lost), and it can use 16-bits of information per pixel (JPG is limited to 8 bpp). 16-bit TIFF is an excellent -- and standard -- file format for high-quality scans.
Are you really still on 10.6.1?

Replacing and retaining scaled and cropped images

Hi,
For some reason I can't find how to replace exisisting images that had been tweeked or even images that have not been tweeked in Author. I have several similar images that needs to be scaled and postion in the same area from page to page. I import an image, scale it and cropped it, but once placed I don't know how to replace it with a different image. I tried creating a a template (another problem), but still no go.
*also, is there a way to create a job without using template? It doesn't seem to allow you it.
Thanks in advance...AG_779

You can have a master image on the right hand page in the layout pane,
and set it to be a media placeholder.(in inspector)
The image will be same size same spot on each page,
You can drag an drop to replace the image on each page.
The problem is, if the new image is a different size (pixels), it will change the size of the place holder frame to match the new image. it will not keep the size of the master image and crop with in that size.
It is best if you scale and crop each image outside of IBA in Photoshop etc. first,
then drag and drop on the place hlder for each page.

VBA code to import scanned images into Photoshop CS2 with TWAIN

Hi,
I have to develop a solution that automates the scanning of an image using the TWAIN driver interface. Once scanned, the image appears as a new document in Photoshop where it will be further processed using VBScript scripts.
The solution so far :
Using the freeware 'EZTW32.dll' (copied into C:\WINDOWS\System\), I am able to open the TWAIN scan dialogue on screen, using the function 'TWAIN_AcquireToClipboard(Me.Hwnd, nPixTypes) from the 'EZTW32' dll.
Once the image is scanned, the TWAIN driver is automatically closed, leaving the scanned image on the Windows clipboard.
I then launch Photoshop CS2 using a shell code :
(It is important that Photoshop runs minimized)
Dim strPathname As String
Dim lngShellReturn As Long
Dim appRef As Object
Dim newDocRef
strPathname = "C:\Program Files\Adobe\Adobe Photoshop CS2\Photoshop.exe"
lngShellReturn = Shell(strPathname, vbMinimizedNoFocus)
Set appRef = CreateObject("Photoshop.Application")
When Photoshop is running, then a new document is created and the scanned image is pasted into the document from the Windows clipboard...
Set newDocRef = Documents.Add(8.268, 11.693, 600, "New Doc")
newDocRef.Paste
OK, this works up to a point. The newly scanned image appears automatically in Photoshop.
The big problem is that when the user makes a change in resolution or draws a selection box in the TWAIN dialog, this data is not recovered from TWAIN, so the image size parameters in the new document cannot be set.
A beter solution would be to write code that emulates the menu commands in Photoshop CS2:
File -> Import -> [Current Scanner]
that launches the TWAIN driver for the current scanner (the code must close TWAIN immediately after scanning). In this case, the resolution and image selection parameters are also imported into the new document.
I am currently refering to the Photoshop CS2 SDK. Do I need to request the Advanced SDK ?
Once beyond this point, then I think I can continue the image processing routines using VBScript as per the SDK.
Any help or other pointers to the TWAIN problem would be VERY APPRECIATED !
Lars

PLEASE IGNORE MY PREVIOUS POST !
I have now fully resolved the TWAIN problem. It works perfectly and is very robust. I am now continuing with the batch image processing for the newly scanned images using the Photoshop CS2 SDK scripting documents, that I find very detailed, well written, and VERY helpful :)
Peace and love,
Lars

Early storage scenario where a scanned image is not linking to the MIRO

Hello All, I'm running into an issue and could use some help. I'm using an early storage scenario with a third party content server integration. After scanning in a batch of FI documents, I go to trans OAWD and bring the docs into SAP and work items are created for the SAP users. The SAP users go into their workplace inboxes to process their documents. They bring up the image in a viewer and click on PROCESS which calls the MIRO transaction. They complete the transaction and click save. The document is created and produces a doc number, we go to trans MIR4 to view the document and it is there and complete but there is no link created between the miro transaction and the scanned image.The attachment list is empty and there is no entry created in table TOA01. If I choose the object services tool bar and store a business document from there, the link does appear and an attachment is made. I can get the attachment to work manually using the object services tool bar in MIR4 but not automatically in MIRO.
To make matters worse, this does work automatically in the DEV environment, but not in QA after we transported the changes.
Any suggestions or ideas on how to get the link to occur automatically in QA would be great.

HP LaserJet 100 colorMFP M175nw scanned images are too bright

Hello!
Is there a way to change scanner's default image color correction as currently all of resulted scanned images (text documents, graphics, photos) are unnaturally too bright?
I had another HP Ink Jet printer also with scanner and all scanned images have good color correction there.
So I think there is a problem with my current one.
Does anyone knows how to fix it?
Thanks.

Hello, Futoji!
Sorry for big delay.
I did what you've told me and now I am wondering about what I see.
1) To scan documents I use both HP Scan and Apple Image Capture with default settings (no color correction).
Well it does not matter, though, because I see bright pictures right after scanning them.
2) I scan documents from flatbed (not feeder), well it is the same for feeder.
3) So, what I noticed was that printer scanned document and printed it almost exactly as it was only using hardware buttons on it.
But when I did scan using both programs above the same document, it was getting too bright to be real... When I printed such scanned image the result was accordingly bad.
So, what I think is that this scanner works differently for hardware buttons and software or applies some filters on the resulted image...
I found 2 similar posts to mine, they are describing the same problem for different printers, but unfortunately they didn't seem to be solved.
