Masters, I know this might have been discussed as I have viewed multiple threads already, but I'm still confused/bothered given those crop factor, ppi issue thingies. Given the following scenario:

Pics taken from a D40>T

Transferred to the PC>

Minimal Post processing done in Photoshop (adjusting sharpness, saturation, exposure, NO CROPPING and NO adjusting those PPI etc)>

Saved it as the highest quality..Created a folder and stored in flash drive>

Now...When I bring the flash drive to lets say for example, Digiprint...will it come out as it is when i request it to be "as it is" in a 4R print?

Is there anything that needs to be adjusted so it will come out as it is in a 4R print?

If there is...Is there a common work flow?

Bottomline is I just want to know how to achieve the very exact photo that I took and and viewed in Photoshop in a 4R print:Grin:. Sorry Im so confused, I hope you're getting my point masters.

Once this one is clear...thats the time I'll clarify those crop, ppi thingies :)

Thanks In Advance

hello mike, your D40 already gives a native aspect ratio of 3:2 out of cam, so you're good to go with normal 4r (4x6) print output as is.

what Bing said is right. and if ever you're going to crop them, make sure they're cropped in a ratio of 4:6

No problem with the cropping if the aspect ratio of 2:3 is maintained.

The only problem of getting it to match in Photoshop and in the print is if you practice color management. :D

Cheers!

Thank You Masters........first time to print coming from a DSLR....now I'm off to Digiprint later :)

One more thing....I experimented to resize the image to exactly 4x6 via photoshop and saved about 20 of them in my thumb drive thinking that it will come out as an exact 4R print as viewed. Did I do the right thing?

Next thing to learn....those aspect ratio, cropping etc....hope you wont get tired answering my queries

Thanks Again!:Grin:

when i have my pics printed, i resize them 3 times bigger than the actual size on prin (inches) so i make my 4x6 a 12x18. i just keep the aspect ratio. i do that so the printers will have enough information on the photo to prevent pixelation.

thats just me, i dont know if that's correct. but i'm OC that way. and that way, if i decide to print it bigger like 8r, i dont need to resize again.

6MP has enough detail for you to be able to print on a 8x10 (8R) size.

Just a quick math to check if you have enough dpi/ppi; :)

Image's Larger Dimension / Print Output's Larger Dimension >= 300

For example, you have 2988 pix by 2002 pixels straight from your camera and you want to print on a 4 x 6 size, following the formula above gives you --

2988 x 6 = 498 dpi which is greater than 300dpi.

Now suppose you want to print the same image to an 8 x 10 --

2988 x 10 = 299.8 dpi which is just .2 dpi away from 300. :)

Andrew

it'll depend on teh printer, but normally it shouldn't be a problem as long as you're working within 240-300 pixels/inch.

as for aspect ratios, it is just the relationship between the width & height of the photograph. you just have to crop accordingly:

4r 4x6 2:3
5r 5x7 5:7
8r 8x10 4:5
s8r 8x12 2:3

last question :Grin: . Is there gonna be a problem if i exceed the ppi values. Coz what happens is when i follow the steps on this article http://graphicssoft.about.com/cs/digitalimaging/f/changeprintsize.htm specially when i check "constrain proportions" and uncheck "resample", I get about 500for ppi.

Thanks

For your prints - NO.

For your computer (if you are printing to your desktop printer) - YES! (But not really) :)
DPI in excess of 300 or 360 dpi will not give you a significant improvement on quality. It will simply take a longer time to print.

Thanks Sir Andrew!!!:Grin:
