I do use a camera instead of scanning. Couldn't understand why my scanner would crop an image like this. I use me scanner quite often and never seen it do this... until I scanned a stamp.

re: Scanning Stamps?

Try lowering the position of the stamp on the scanner bed. Printed documents typically have a boarder without printing so the documents position is less critical on the scanner bed.

re: Scanning Stamps?

The general theory is, if you're scanning a single/set of stamps, place the stamp DIRECTLY in the center of the scanner.

I've had people say keep the scanner top open, to insure a dark background.., but it'd never worked for me, I'd just end up with white borders/perfs on white backgrounds, and my software tended to just 'chop off' the all-white portion (like on your scan), unless i went in and ignored the default settings.

Get a single stamp holding card (or something similar) to stick behind the stamp when you scan it, and it _shouldn't_ chop anything out.

re: Scanning Stamps?

For all it is worth:
Often, when we place small objects--i.e. stamps--on the scanner bed the said object slides off its intended position, thus creating a not so very straight image on your computer. In order to minimize this problem, try the following solution--with a great deal of care:
use a photo album "Photo Safe" Adhesive self-stick page from HOM. (This product can be found in any Target photo album supply section. (I did not look anywhere else...)
Draw a simple matrix or grid with pencil and ruler to help you place the stamps straight. Place the stamps you wish to scan on the self-adhesive page very carefully. Then run the clear plastic sheet protector that comes with the self-adhesive page over the stamps. You may encounter the following problem: the clear plastic page will create air bubbles and will move the stamps. It will take practice to obtain a 90% non-sliding stamp on the self-adhesive page.
Place the sheet on the scanner bed. You will make sure that there are good margins, of course. Scan your picture. Save it to your desktop and give the temporary file a name. (Usually the file name will be the date you create the document, i.e. 12/3/2013.)
Now, use a paint--graphic editor--program (I use Windows Paint, the most basic picture editing program for PCs. No complications...)
Go to Paste, and Paste from... Get the file you created on your desktop. It will show extremely big on your screen. No problem. Go to View and Zoom out until the image shows up at a good workable size. Now, go to Select and choose the Rectangular selection tool. Go to any image from those you scanned, and place the "square with the broken little lines" around your selected image. Use the Crop tool. The image will now appear by itself on the Paint Drawing board. Go to the drop-down arrow which is to the left of Home.
Choose Save as... and choose JPEG picture. The picture will be saved to the Desktop under a date file, unless you create a folder with a specific name on the Desktop. Give your individual picture a name, for example, the picture you see below is "roosevelt3cents". As you can see, the picture is pretty straight.
If you do not wish to go through all the problem with the Self-adhesive album sheet, you can use a black or white stock sheet.

Sorry for taking so much space!!!

I know it's about a year late, but for Tuscany4me, check your scanner software to see if you have "autocrop" selected. Looks to me like the scanner is cropping the image itself.

Download Irfanview. Best scanning software around, and it's free. Crop, resize, straighten. Can also use it to adjust your camera produced images.

re: Scanning Stamps?

I have professional image processing software because of my work. (It's not Photoshop, but similar). It's nice to be able to rotate in tenths of a degree and lay images on top of one another (like a stamp on a perf gauge or millimeter ruler) and add precisely parallel lines to check the edges on a suspect coil. I don't do it that often, but it sure comes in handy when needed.

I used it to figure out why a 350 coil came back as a fake:

Image Not Found

I had another 3rd Bureau coil that came back as a fake, but I couldn't see why it was a fake. I sent it back for another evaluation and it was STILL deemed a fake. So I sent it to PSE and got a GENUINE cert. Quite a learning experience!

Image Not Found

If you want to see the certs, go to http://www.larsdog.com/stamps/beyond.htm and scroll down to "Fakes, Forgeries, and Facsimilies"

The upper sections are undergoing a complete overhaul, so ignore the top part of that web page if you go to that link.

re: Scanning Stamps?

Add to the auto cropping, is after the scanner is done and loaded an image, look to see if there is a dotted or dashed box that can be moved or stretched, some times I get more then one box and I have to delete one or more of them. After you see the dotted box is at its largest or covering you stamp, then hit scan, or done.

It makes me mad to rescan because of these Angry

re: Scanning Stamps?

When scanning stamps I have been using a resolution of 300 dpi. This works well for single stamps, but when I scan a set of stamps the resulting size is too large for SOR auctions.

What DPI should I be using for scanning stamps to be posted on SOR for single stamps or sets or a whole page?

re: Scanning Stamps?

Hi Doug:
I also scan full 8 1/2 x 11 pages at 300 dpi
The saved file (viewed on Irfanview) is 2550 x 3300 pixels.
I then go to Image, Resize/resample, and I reduce it by 39%...aiming to get as close to 1000 pix as possible.
The resultant file is actually 995 x 1287 pixels, which is accepted by SOR, and gives relatively good quality for full page scans (check my books under Approval). I like more sharply defined perforations against any background, so I sharpen the image (once or twice) and save it...the darker the background, the less necessary this step is, but it does depend on your scanner.
I know that sharpening impacts image quality, but I like to highlight perforations, defects, cancellations, and details more than true color or just resolution. Works for me, but just try it as final settings is a matter of preference. So Scan at 300. Resize. Sharpen. Save. The whole process (after you scan) takes under 2 minutes. ( Yes, I have been timing). Once you know what works..repeat for every page scanned. Voila!
Good luck
rrr....

re: Scanning Stamps?

Doug

For full pages, I scan at 200 dpi then resize (using Irfanview) to a width of 900 pixels (length is OK as long as it is under 1225 pixels, if it is too long, I reduce width to 800 pixels). Since I use a black background, I do not need to adjust my image to show details of the perfs. I also "fill" the background with "absolute black" (use "paint dialog" under the edit tab) to highlight detail without changing the stamp color or sharpness. Check my scans, they are very detailed and can be increased in size to give buyers more to look at. I like to leave my scan as close to an image of the actual stamp as possible. If you use a white or light pastel paper, you will need to do as Ralph does to show the details of the perfs.

Also remember that scanner quality may differ from brand to brand. I have always been happiest with Hewlett Packard.

Play around with some images. You may find something neither Ralph nor I use that pleases you and presents a nice display. There are many roads that lead to the same destination, take the one less traveled and you may enjoy the trip more.

re: Scanning Stamps?

I used a Canon LIDE 200 scanner that comes with a very easy to use, and free, PhotoStudio 5.5 software package. I scan my stamps at 600 dpi, and then reduce the scanned image in size anywhere from 500 to 700 on the longest side. When I save it as a jpg file, I keep it at 100% and check the resulting size. If it is 300kb or greater, I change the size accordingly and resave. All of the stamps you see posted in my approval books, for example, are 250 to 280 kb size.

I'm not sure how this translates to other software or scanner programs, but that's what I use.

re: Scanning Stamps?

No wonder scanning has the aura of black magic:

Ralph: 1) initially scan page at 300dpi.
Bobby: 1) initially scan page at 200dpi.
Peter: 1) initially scan page at 600dpi.

All: 2) then do something to reduce the image which is too large.

Arno: scan page at 100dpi into a jpg file and be done with it. In all of my approval books, I scanned pages at 100dpi and did no further adjustments of any kind. Now, this is not optimal, because the system will accept images that are a bit larger. You will get probably somewhat better results, if you scan at more than 100dpi and manually reduce size. But if you want to avoid these extra steps, my pages give an idea how plain 100dpi without any adjustments look like. I use the no frills Windows Scanner and Camera Wizard which comes with the computer. NB: this is for scanning a whole page of stamps. For images of individual stamps to be posted in the auction, 200 or even 300 dpi are much better. Also, all of my books thus far have been black or colored pages. White pages are not good and may require extra work to improve the image, because there is not enough contrast.

re: Scanning Stamps?

The difference is in the quality of the scan. If you scan a single stamp, this may not matter but if you have a large sheet of stamps (as with an approval book) you do lose some detail and sharpness with a 100 scan. It isn't major, but I'm just picky enough to want the best scan I can get so that's why I use 300 or 600 for my scans, then reduce the size. The sharpness is maintained. Here are two examples of one block of four cropped from a scanned sheet of seven blocks. I then cropped and resized the images to 600 pixels on the longer side.

This was from the 600dpi scan:

Image Not Found

This was from the 100dpi scan:
Image Not Found

Not that much different but the top scan is much cleaner and clearer. It takes just a bit longer to scan at 600 than 100, but the result is worth it IMHO.

When I did not resize the 100dpi scanned image, the result was smaller of course (around 240 pixels) and still not clear.

Image Not Found

Tradeoff: Better quality scans for your images, vs. time involved in scanning. I'd opt for the former.

re: Scanning Stamps?

What am I doing wrong? I have always found scanning a problem. I have Windows 10, and to get the image into shape I use Picasa. I have just bought a pretty basic home 3 in 1 printer - it's a Canon pixma 3560. After half an hour trying to find how to set the resolution and how to send to the right folder etc, I realised it does all that automatically. I haven't yet found if it's possible to adjust the resolution. It scans andd sends image identified by string of letters and numbers to the My Docs folder. So I put 5 stamps (Newfie, if you're interested) on the platen, covered by a black card. So how to get 5 scans? My method is to copy the image 4 times then move a copy to picasa to be cropped and straightened. The tricky part is getting the image into picasa. Then it's exporting the result to the right folder.
The whole job takes ages and involves lots of profanity.
I've tried photobucket without success. Trouble is, the programs seem to assume you know how to use them. picasa is the same, hence me floundering about trying to get my scan from My Docs into the right place in picasa. Grrr.
So, what can I do to make all this easier?

re: Scanning Stamps?

I just bought a 3 in one printer (Brother) but have a scanner (Epson V330) which I use for scanning. Had it since probably 2009 or so. Came with awesome software and a package called Media Impression which is probably free to download these days. I do my page numbering and compression with Jasc Paint Shop which dates back to 2001. The two programs allow me to scan full pages, use Jasc for numbering and crop with Media Impression, though to be honest, the Jasc would crop as well. I still use XP and will always use XP until such time that my anti virus software no longer supports it.

As an aside, for the 100 auctions I create on Wednesday, scan,crop,resize if too big and save (and sometimes renumber because I forget the auction image rules) takes less than 30 minutes

I agree that IrfanView is the best and is easy to use with lots of tools.

I would not use those albums with the sticky surface for photographs. I have seen people use them and end up ruining the stamps.

re: Scanning Stamps?

I have professional image processing software because of my work. (It's not Photoshop, but similar). It's nice to be able to rotate in tenths of a degree and lay images on top of one another (like a stamp on a perf gauge or millimeter ruler) and add precisely parallel lines to check the edges on a suspect coil. I don't do it that often, but it sure comes in handy when needed.

I used it to figure out why a 350 coil came back as a fake:

I had another 3rd Bureau coil that came back as a fake, but I couldn't see why it was a fake. I sent it back for another evaluation and it was STILL deemed a fake. So I sent it to PSE and got a GENUINE cert. Quite a learning experience!

Image Not Found

If you want to see the certs, go to http://www.larsdog.com/stamps/beyond.htm and scroll down to "Fakes, Forgeries, and Facsimilies"

The upper sections are undergoing a complete overhaul, so ignore the top part of that web page if you go to that link.

re: Scanning Stamps?

Add to the auto cropping, is after the scanner is done and loaded an image, look to see if there is a dotted or dashed box that can be moved or stretched, some times I get more then one box and I have to delete one or more of them. After you see the dotted box is at its largest or covering you stamp, then hit scan, or done.

It makes me mad to rescan because of these Angry

re: Scanning Stamps?

Did "irfanview.com" go in the healthcare bucket? Hypnotized

I tried 3 different sites and they said file or program not found.

I do a lot of scanning and can use it.

Can you help get it?

Thanks

re: Scanning Stamps?

When scanning stamps I have been using a resolution of 300 dpi. This works well for single stamps, but when I scan a set of stamps the resulting size is too large for SOR auctions.

What DPI should I be using for scanning stamps to be posted on SOR for single stamps or sets or a whole page?

re: Scanning Stamps?

Hi Doug:
I also scan full 8 1/2 x 11 pages at 300 dpi
The saved file (viewed on Irfanview) is 2550 x 3300 pixels.
I then go to Image, Resize/resample, and I reduce it by 39%...aiming to get as close to 1000 pix as possible.
The resultant file is actually 995 x 1287 pixels, which is accepted by SOR, and gives relatively good quality for full page scans (check my books under Approval). I like more sharply defined perforations against any background, so I sharpen the image (once or twice) and save it...the darker the background, the less necessary this step is, but it does depend on your scanner.
I know that sharpening impacts image quality, but I like to highlight perforations, defects, cancellations, and details more than true color or just resolution. Works for me, but just try it as final settings is a matter of preference. So Scan at 300. Resize. Sharpen. Save. The whole process (after you scan) takes under 2 minutes. ( Yes, I have been timing). Once you know what works..repeat for every page scanned. Voila!
Good luck
rrr....

re: Scanning Stamps?

Hi Doug,
I would probably scan at 100bpi and you will get a good result that should work.

re: Scanning Stamps?

Doug

For full pages, I scan at 200 dpi then resize (using Irfanview) to a width of 900 pixels (length is OK as long as it is under 1225 pixels, if it is too long, I reduce width to 800 pixels). Since I use a black background, I do not need to adjust my image to show details of the perfs. I also "fill" the background with "absolute black" (use "paint dialog" under the edit tab) to highlight detail without changing the stamp color or sharpness. Check my scans, they are very detailed and can be increased in size to give buyers more to look at. I like to leave my scan as close to an image of the actual stamp as possible. If you use a white or light pastel paper, you will need to do as Ralph does to show the details of the perfs.

Also remember that scanner quality may differ from brand to brand. I have always been happiest with Hewlett Packard.

Play around with some images. You may find something neither Ralph nor I use that pleases you and presents a nice display. There are many roads that lead to the same destination, take the one less traveled and you may enjoy the trip more.

re: Scanning Stamps?

I used a Canon LIDE 200 scanner that comes with a very easy to use, and free, PhotoStudio 5.5 software package. I scan my stamps at 600 dpi, and then reduce the scanned image in size anywhere from 500 to 700 on the longest side. When I save it as a jpg file, I keep it at 100% and check the resulting size. If it is 300kb or greater, I change the size accordingly and resave. All of the stamps you see posted in my approval books, for example, are 250 to 280 kb size.

I'm not sure how this translates to other software or scanner programs, but that's what I use.

re: Scanning Stamps?

No wonder scanning has the aura of black magic:

Ralph: 1) initially scan page at 300dpi.
Bobby: 1) initially scan page at 200dpi.
Peter: 1) initially scan page at 600dpi.

All: 2) then do something to reduce the image which is too large.

Arno: scan page at 100dpi into a jpg file and be done with it. In all of my approval books, I scanned pages at 100dpi and did no further adjustments of any kind. Now, this is not optimal, because the system will accept images that are a bit larger. You will get probably somewhat better results, if you scan at more than 100dpi and manually reduce size. But if you want to avoid these extra steps, my pages give an idea how plain 100dpi without any adjustments look like. I use the no frills Windows Scanner and Camera Wizard which comes with the computer. NB: this is for scanning a whole page of stamps. For images of individual stamps to be posted in the auction, 200 or even 300 dpi are much better. Also, all of my books thus far have been black or colored pages. White pages are not good and may require extra work to improve the image, because there is not enough contrast.

re: Scanning Stamps?

The difference is in the quality of the scan. If you scan a single stamp, this may not matter but if you have a large sheet of stamps (as with an approval book) you do lose some detail and sharpness with a 100 scan. It isn't major, but I'm just picky enough to want the best scan I can get so that's why I use 300 or 600 for my scans, then reduce the size. The sharpness is maintained. Here are two examples of one block of four cropped from a scanned sheet of seven blocks. I then cropped and resized the images to 600 pixels on the longer side.

This was from the 600dpi scan:

Image Not Found

This was from the 100dpi scan:
Image Not Found

Not that much different but the top scan is much cleaner and clearer. It takes just a bit longer to scan at 600 than 100, but the result is worth it IMHO.

When I did not resize the 100dpi scanned image, the result was smaller of course (around 240 pixels) and still not clear.

Image Not Found

Tradeoff: Better quality scans for your images, vs. time involved in scanning. I'd opt for the former.

re: Scanning Stamps?

What am I doing wrong? I have always found scanning a problem. I have Windows 10, and to get the image into shape I use Picasa. I have just bought a pretty basic home 3 in 1 printer - it's a Canon pixma 3560. After half an hour trying to find how to set the resolution and how to send to the right folder etc, I realised it does all that automatically. I haven't yet found if it's possible to adjust the resolution. It scans andd sends image identified by string of letters and numbers to the My Docs folder. So I put 5 stamps (Newfie, if you're interested) on the platen, covered by a black card. So how to get 5 scans? My method is to copy the image 4 times then move a copy to picasa to be cropped and straightened. The tricky part is getting the image into picasa. Then it's exporting the result to the right folder.
The whole job takes ages and involves lots of profanity.
I've tried photobucket without success. Trouble is, the programs seem to assume you know how to use them. picasa is the same, hence me floundering about trying to get my scan from My Docs into the right place in picasa. Grrr.
So, what can I do to make all this easier?

re: Scanning Stamps?

I just bought a 3 in one printer (Brother) but have a scanner (Epson V330) which I use for scanning. Had it since probably 2009 or so. Came with awesome software and a package called Media Impression which is probably free to download these days. I do my page numbering and compression with Jasc Paint Shop which dates back to 2001. The two programs allow me to scan full pages, use Jasc for numbering and crop with Media Impression, though to be honest, the Jasc would crop as well. I still use XP and will always use XP until such time that my anti virus software no longer supports it.

As an aside, for the 100 auctions I create on Wednesday, scan,crop,resize if too big and save (and sometimes renumber because I forget the auction image rules) takes less than 30 minutes
