300 vs 400 - Noticable?
 
Has anyone had the opportunity to look at a 300 dpi next to a 400 dpi dye-sub print (ie the HiTi 640 4x6 print vs the 730 4x6 print)? Can you tell the difference?

The one place that I can see a potential impact is with text overlayed on the image. Then again, maybe not?

Thanks

You can tell at about 15X magnification. I put two pictures under the microscope at work.
To the naked eye, the Hiti 630 and 640 pictures are indistinguishable.

I have owned the 630 and 640 and could tell no difference between the output of the two printers.

So I guess the 730 is the best of both worlds? Picture quality would be equal to the 640 and you have the flexibility of different size prints.

Getting ready to buy a printer!!!

Stan,
That was my very reason for asking this question. IF the lower resolution is imperceptable, the 730 seems like it would be worth the extra costs.

I agree. I am going to order a 730 !

Let me do some math: :idea:

301dpi*4"=1204 pixels, 301*6=1806, 1.204*1.806=2.17 Mpix

403dpi*4"=1612 pixels, 403*6=2418, 1.612*2.418=3.89 Mpix.

Am I correct, and we can only find the difference between 2 Mpix print and 4 Mpix print under 15x magnification? :-)

What a relief - I was looking at 8 Mpix cameras to replace my old Minolta s404 :shock:

By the way - did anyone play with that "magic coating" - transparent printing on the coating layer? What if we makesome foreground areas glossy andthe rest of pictureleavematt?

Sort of...
2 and 4 MP will look identical to the naked eye when printed at 4X6 inches. Bigger prints are where the differences show up.

Then I'll continue with math. :-)

That'show big the 4 Mpix print should be to look better than 2Mpix:

15x4" by 15x6" is 60" by 90". Either my math is wrong, or 2x or so magnification should be enough to see the difference between those prints.

Sorry for being picky, it comes naturally :-)

Regards,

Alexey.

It looks as if the Hi-Ti 730 might be the way to go. What are the differences between the 640PS and 640GALA?



Thanks in advance,



Mike
