Greetings all,
I'm working on some software, and before making a certain design decision, I wanted to ask some other collectors their preference.
Let's say you've scanned a stamp, so now you have this nice, high-resolution photo of your stamp.
Do you:
1. Save the photo as-is;
2. Resize it based on height (ex. 600px high);
3. Resize it based on width (ex. 600px wide);
4. Some combination of 2-3, depending on orientation (ex. tall stamps resized by height, wide stamps by width);
5. Resize it based on a percentage (ex. shrink it 50%);
6. Resize it based on some other method of determining size.
Thanks in advance.

Hi Postmaster, nice to see you back. Personally, I find scanning at 600dpi the best for all my stamps, I believe it gives good clarity, for flyspecking etc, and a small footprint (I have 400,000 images on a divorced HDD) I scan at 600 dpi = 869x1822 *.jpeg (390Kb) Open the scan with Picasa and deskew, then save Scan reduces to 662x1674 (266Kb) which is around the size of all my stamps. If I scan an album page, I reduce the scan to 200dpi Hope this helps in some way. Scan at 266Kb..........  |

I scan a stamp at 600dpi with no image adjustments and save as a .jpg. I then open the .jpg in IrfanView, resize it to a width of 1024 pixels, and save it at a file size of 99kb.  When scanning pages, I'll scan and resize as for stamps but increase the file size to 300kb or greater avoid a loss of image quality. |

Thanks for the input, everyone. Here's a short preview of why I needed the info.
It's not quite ready for distro, as I still have a few bugs to work-out. I hope to have it finished within a week or two, day-job permitting.

Wow! Absolutely Brilliant ! sign me up, how much Postmaster? I'll Paypal you.
for years I have been doing single stamps in Picasa, this is a revelation.
Love the "padding" option.
I have >400,000 images, It will be put to work.
Question: When I scan a William Steiner page, it has the black rectangle border, would this program deskew and crop also?
Desire: A program that could take the first 6 positions of a file name, delete and rename.
example: I am changing over from Stanley Gibbons to Scott and all my files begin with SGxxxx.
Anyone?

Great job! What an excellent time saver. I also do these same steps on each stamp in Picassa, how awesome to process a whole batch at once.

PostmasterGS Many thanks for the renamer, my ACDSee can add text, but not replace portions. Deskew and crop an album page: Example, scan of a standard Australian A4 album page, from the scanner platen. I manually have to draw a carousel around the border, and crop. Would your program handle that?

rod222, Are you trying to crop around the outside of the entire page or the inner black rectangular border? If the page, maybe. If the inner border, no, since it needs a black background to properly detect the edges.

I thought as much, considering your software has to detect the perforations. Thanks. |

Wow, that looks really neat, Postmaster. Curious whether your program, or another utility, will take a scan of a page of stamps and crop them into separate image files? From the video, it looks like that step had already happened. Do you have a tool for that too?  Mark PS. I use Irfanview, and can be pretty fast with my keystrokes, but your app looks much faster and more precise. |

I have recently retired and am incorporating my office equipment into my daily life (heaven forbid I should toss anything). I have recently been experimenting with my Scansnap desktop scanner (feeds anything flat through the scanner really fast). When I send a sheet of mounted stamps through, it will auto crop each stamp on the sheet should I desire. It is also great for scanning covers and postcards as it copies both sides in one pass. The major drawback (and why you need to keep your flatbed scanner) is that there can be no protuberances or they will get caught in the roller and ruin the stamps. I solve this by inserting the sheet into a sheet protector. New, they are fairly expensive ($250 and up) but used they can be very reasonable. If I didn't already have one, I would not go out and purchase one since I couldn't justify the expense merely to save a little time, but if you have an opportunity to pick one up cheap (I have seen similar at Goodwill), give it a shot.
some examples here
Edit: The sheet protector does not always work. I was going to scan some examples, but the sheet protector was too wide and caused a jam in the rollers. Still trying to get the dad-gum thing out! |

Probably the best buy on that page is the Canon Office Products LiDE120
About 1 year ago I got the updated version LIDE 210 for $49 CAD / $32US
The really nice thing is no power cord, it powers from the USB connector
At least, I think my scans that I post are reasonably good

The app won't yet split a page into individual images, but I'll consider that for future development. There's another app out there by Jason Drake which does this. Also, some scanning software (I use Epson's) will allow you to draw boxes around the individual stamps before scanning, and each will be scanned as a separate image file. That's how I get mine separated. |

Cool. Thanks Postmaster. I'll have to dig into my scanner software - that's a neat trick.
I've played around with Jason Drake's software too. Must've had it in mind when I asked the question. Thanks for the reminder!

That is why I prefer the flatbed scanners - I am scared the feeder type would swallow my stampers for ever!

All collectors should have a stand alone flatbed scanner. Best thing I ever did was buy a scanner thanks to the nagging from rod222  |

Your scans are truly great. How about a step-by-step guide, using your Canon 9000 MkII and your software/settings of choice? I think it would be interesting to many people (myself included). |

How about a step-by-step guide, using your Canon 9000 MkII and your software/settings of choice? I think it would be interesting to many people (myself included). Scans of reasonable quality can be achieved by anyone with 1. A dedicated flatbed scanner preferably a CCD imaging type (not CIS) - the better Epsons or Canons will have this feature. However my old Canon CIS LIDE 210 did a very good job.
2. Scanning software that allows for a wide range of options. Preferably one that offers RAW scans as opposed to jpg/tiff/png. Most that come with scanners are lacking controls. The BEST out there is VueScan PERIOD! 3. A color chart to calibrate your scanner for desired results. Kodak color guide or Macbeth ColorChecker will do fine. Scanners tend to be good on reds, not so good on blues or the reverse so its a matter of compromise From there I have saved preferred multi color, single color and greyscale profiles in the software so I can bring up what I need. As for resolution the options I set at 300/450/600 DPI - no need for anything bigger for basic forum posts or archiving.
I should add that hopefully you have a reasonable computer/monitor with a decent dedicated graphics card so you can see the results.
For really nice images with depth (like embossed stamps) I have used a digital camera with a specific setup but a hand held, room light, IPhone won't work.

Went to Walmart this morning to check on the Lide scanners (I used to have one in my Motorhome) - non on hand but they advertise it - You can order online, free shipping to your Walmart - probably will order one since my Canon upgrade does not do the trick and I should have known after reading nl1947's many advices on a dedicated scanner. $40 for another useless Canon all in all TS3120 bought last week - It is a very good copier however so I keep it, but not for scanning !!

I think it would be interesting to many people (myself included). , I think you are absolutely right. Nelson's (@falshung) scans are indeed, truly great. Thank you for making this request. Nelson, thanks, as always, for your superior quality contributions to TSF. All of us benefit from what you do! |
