Does this make sence

[8ball]

I have an image being blown up into poster size

Best case it needs to be 24" x 36" at 150 PPI.

The one that we have will only be 22PPI at that size

If I go into photoshop can I set the image size to 24X36 150 PPI and save it that way and then when I send the file to the printer it will be all good?

 

[8ball]

bump!

No.

It depends on the resolution of the image. What is the image resoltuion? Something like 3000x2000?

 

[8ball]

Im not 100% sure what should it be set to for a 24x36?

 

[8ball]

Pppplease help me!

Boom was trying; you didn't answer his question! What is the resolution of the image right now?

You cannot add resolution to the image...

Unless it is a Vector image, but more than likely it isn't.

I'm not a 100% sure on the res because it is on my computer at home and I am at work I will check once I get home and post it up

did you crop it? You would know just by knowing your camera resolution.

 

[8ball]

I'm unsure of my camera resolution 3000x2000 sounds very familiar though
No it is un croped.

 

[Robin Usagani]

???? How could you not know your camera resolution??? How many megapixels??? You can google it and it will tell you.

 

[8ball]

well its a d300 so the megapixle is 12.3
when I open up the file in photosho and then clikc on the image tab this is what it reads
Pixle dem:
w: 799
H: 535

doc size
W 3.329
H 2.29

res 240

Not completely true, at least not in practical terms. There is software which, through interpolation will allow you to increase the effective resolution of an image. It's not a great solution, but for poster-size images which aren't likely to be viewed from close up, it's workable.

 

[Robin Usagani]

12,300,000 = 2x * 3x = 6 x ^2
x = 1431

So your resolution should be 2862 x 4293.

 

[Robin Usagani]

So basically right now you have 4293/36 = 120 ppi which is ok for a poster (assuming you didnt crop it). Not the greatest but you wont look at it too close.
