High Res scanning of 35mm negatives @ $6 per roll 36exp only~!

[AgnesKjaer]

12R means the width of the <a href="http://www.ntsearch.com/search.php?q=photo&v=56">photo</a> is 12",if it the image ratio is 3:2,means 12"by 18"

if it is a 4:3 image it is 12"by 15"

A3 should be ard 12"x16" if i remember correctly.

so i can say the img quality is perfect for A3 prints? how do i find out or know wat's the img ratio?

 

[kex]

erm..

image quality is acceptable for A3 at a further distance.3818 dpi is only slightly more than 200dpi for 18"
most printer can print at 300dpi or abit more for this type of enlargement,y 300?coz our eyes can only differentiate up to 300dpi.
for bigger enlargements,becoz of the viewing distance,printing is mostly ard 200-250dpi only.
image ratio is the size of the length and the width of the image.
35mm neg size is 24mmx36mm u bring down the ratio is 2:3
for most consumer digicam,it is 4:3 ie 1600x1200
hope it helps.

ok.. i can let pass a bit of grains or noise when view at close up.. inevitable though... mm... wil be gg off to shoot soon so hope i can give a try at ur svc! so wats ur add n operating hrs bro?

 

[satan_18349]

pls pardon my ignorance to the sizes.. 12R is about.....A3, A4?

A4 = Super 8R

Hello Kex,

Can I have your details too?

Thanks.

Hi kex,

I have done some scans at your place both in jpeg and tiff format . . .
T
he resolution of the files (3818 x 2545 ~ 9MP) is great . . . but i realise that they are all done at 20dpi (both jpeg and tiff). At 20dpi when it is blown up to 100% on Photoshop, it does show grain and noise.

Is this the default of the scanner or the setting you have chosen to use? Any way to scan at higher dpi . . .

Compared to the FDI shops, they are usually scanning at 300dpi (up to a 6MP file)

Too lazy to go through the entire thread so just asking again.

1) Does -ve comprise of black and white -ves?
2) Higher DPI than 20 is possible?
3) How about +ves?

20dpi or 1000dpi, it makes no difference if you are view only on the computer so long as your resolution is 3818x2545. I do not think the FDI scan at 300dpi because DPI stands for dots per inch (closely linked with Pixel Per Inch or PPI) and if it is scanned at 300dpi it will produce a 450x300 (or slightly smaller) image output. DPI or PPI is only important if you intend to send your image for printing as you need to calculate the output size and with the resolution you working with.

DPI x Output size (in inch) = Resolution

Example:

300DPI x 4 by 6 inch (4R) = 1200 x 1800 resolution (or Pixel)

Same resolution on a larger print:

150DPI x 8 by 12 inch = 1200 x 1800 resolution (or Pixel)


So to me resolution is important only when you need to know how big your image will be when doing the publishing (example in photoshop) and when you publish it (print).

 

[chaotic]

20dpi? 20 dots per inch will result is a super low resolution file given that the film negative sizes are barely one or two inches long and wide depending on format.

You should probably ignore that setting in the file. it's irrelevant field that the scanning program just puts in a number for fun. a 9MP file shows that you did receive a high resolution scan and if you view at 100%, please don't expect no grain and noise. It's not a miracle.

hi. can you pm me your address/hours/contact no. pls? rgds.

Erm it's also important when scanning. (input) You need to decide how high resolution a scan you want from your negatives.. the typical consumer film scanners can scan from 2800dpi to as high as 5400dpi.

 

[kex]

Espn: -ve does include B&W but in 35mm format.

the 20dpi thing is not accurate,dpi is 3818/the length of the film(36mm=? inches?) area which is ard 1000+

positive does not scan as well as negatives,but can be done.

more DPI does not = better quality

the quality of the scanning device,how the negative image is projected and the type of sensor that scan the image will determine the scan quality.

i can bet my imacon 2800dpi can produce a file that is far superior than any consumer range scanner.

for the $6 16base scan,resolution is by default..it is the highest res liao.

some frontier or issit all frontier res is ard 3600x2400 compared to my 3818x2546 which is slightly higher..

 

[espn]

Kex: Yeah I'm looking at getting my +ves and -ves done all at one shot, about 10-15 rolls, all 135 format. Your machine cannot do +ves?

 

[kex]

can do positive,but not as good result as negatives..

coz i dunwant to overate the quality.

highlights tends to blow out in the +ve.

 

[LKSC]

espn: The Imacon can extract almost everything from a negative, and Kex provides good service, but to get the best out of positives you need drum scanning.

 

[kex]

my imacon handles negatives and positive VERY well.

But it does comes at a price too.

so still, to print on a3 with the $6 scan is acceptable right? :sweat:

 

[AgnesKjaer]

hi just to enquire, do u charge lower if we dun need such a high res?

 

[kex]

so still, to print on a3 with the $6 scan is acceptable right? :sweat:

if u are not viewing it at 5cm,it should be fine.

Very subjective la,diff pp have diff standards.
