This download site is excellent Ian :4_17_5:
Keep em coming ;)
That flu can be bad to shake off :(
so take some more time off and upload to keep yourself occupied ,whilst recovering ;) ;D
Doctor's orders :)
hunterdubber:
How is it possible for someone to upload or send scans to you or the site Ian?

Hope you dont stop uploading and i hope you feel appreciated - i know i do really appreciate your efforts - brings back so many memory's - thanks again mate - i know i couldn't even afford to go out a buy the mags and books you have uploaded so a big thank you from me :4_17_5: :daumenhoch:

I bought an A3 Scanner after Christmas. A Mustek 1200dpi one at £100.
My old scanner was too crappy and the lid wouldn't remove to make it easier for books or awkward scans.
I did a lot of experimenting. Found that 300 DPI gave me the best results Vs time and effort.
kdw712 scanned Freestyle BMX Vol1 Issue 2 at the weekend for me. His scan was 700 DPI and should have been 4 times the resolution of my scans and 4 times better quality then my scans, but he rescaled the image and saved it as a JPEG. His original scan was probably saved as a JPEG. The end result looked okay when I first viewed it at work but when I got home and inspected it, it wasn't as good as I first imagined.
I hope I haven't put him off. I will not be able to make a complete collection of mags and books without his and other people's help. kdw712 has been the only person apart from hunterdubber today who has made an effort to help with this project.
After my expermentation this is what I have found.
All Scans in 300DPI. (700DPI isn't needed and the difference between the two didn't justify using it).
When you do your original scan, save in a lossless format. I use .BMP. That way you can rotate, cut and paste and know that you won't destroy the quality of the original scan. JPEG's are lossy. They are a compression technique. They may look the same as you original image but they are NOT.
When you a happy with what you have. Convert to JPEG but keep the original image (in case the conversion to JPEG is crap).
Never ever RESCALE the image. If you scan in 300dpi and the resolution of your image is for example w=3000 & h=6000. When you rescale the image to w=1500 & h=3000 you have just converted your image to 150DPI. You would have got a better image if you just scanned in 150DPI.
JPEG's are CRAP. They are lossy. ONLY convert to JPEG as a Final Step after you are completely happy with the original scan. Convert to JPEG and check the quality. If its not so good then change the properties of the JPEG's compression until the JPEG closely matches the original scan. You should be able to zoom in on small text and still read it.
If you convert to JPEG. Rotate it, perform contrast enhancing techniques, rotate it again. You end up compounding errors into the image. JPEG's are only an aproximation of the original image using compression techniques. Doing anything to JPEGs, will gradually destroy the quality of the image over time.
I personnally don't perform any enhancing techniques on my images. What you see is what you get.
I scan in .BMP. I rotate the image if needed. I crop the image if needed. Thats it.
Once I have scanned a full mag/book, I then convert to PDF. The PDF program then uses its own compression techniques to shrink down the images. But it never RESCALES the image, it only shrinks the file size.
A PDF of BMP produces a smaller PDF then when I PDF a JPEG of the same image. You might wonder why. Its because the .BMP is a cleaner image. The white is white and the black is black. The JPEG isn't as white and black. When it PDF's the JPEG it has to decompress the image and then recompress the image and all the aproximation errors built into it. Thats why it can't make a smaller file size than the .BMP. Its hard trying to compress an image that isn't as pure as the original due to the NOISE and Artifacts built into the image when its been compressed.
If you view my scans you should be able to read all the text of those crappy small shop adverts in the mags. Use the Zoom function. As this hopefully going to be the definitive Old School UK BMX Collection, everything must be readable. If you notice any pages that aren't readable in my scans or any errors then please point them out to me. Most the the scans I only skimmed through.
I hope I haven't put kdw712 off by being so critical over his scans. This is a big project and I do need help. I am also missing quite a few magazines as well. I think I have most books though.
If anyone has any scans then please PM me and we'll sort it out. Don't scan a full mag without checking the quality first. you might be wasting your time.
A magazine with 32 Pages = 800 MB in .BMP format
To help everyone here are 2 TEST images for you to download and check out.
An A4 size .BMP is width =2478, Height= 3505 (pixels) at 300 DPI @ A4 size
heres a link to the RAR file of the original TEST .BMP

heres the link to the Jpeg file of the original BMP. (No rescaling)

Thanks for the interest.
