Since I've wanted to print out one of my pics at the size of 90x60 cm, I went to one of my friends, who works in a print center. I've got an Eos450D and ofc I'm using the highest resolution and also Raws.. Nevertheless, my m8 says that he's not able to print those pics in the proper size, when he actually sees the pixels at 400%..

However, I checked all my stuff, I'm using all the right settings and now I wonder - is it just my camera or also yours?

It all depends on the dpi (dots per inch) of the print, I think that 100dpi for a big print is acceptable.
To not have the actual pixels showing just upres the file:
In photoshop just change the file size ctrl-shift-i or in camera raw just select a bigger resolution from the options below.
Obviously the detail will be the same but at least you wont be seeing the actual square pixels.

Good luck.

90 cm is a pretty big photo. I don't think my camera can do that big either - so it's not just yours ^_^. I am using a 400D lol - yours even bigger!



Hey - how do you check how many DPI your picture has? I've also wanted to print a bigger photo.

Yeah, I realize that. TYPO!

Oh, weird, then I guess there's no way of telling because I don't have the printer.

100 DPI is debatable, it really depends on what distance you're expecting people to view the picture at, I've been told at a professional printing place that I shouldn't try for anything below 150 DPI.

As far as printing, what process are you wanting to use? Inkjet, C-type or lightjet?



Right click your photo and view the properties, it'll be there. You can also see in Photoshop, when you go to resize the image (alt + ctrl + i) it'll be in the document size section.

well problem is that my photoshop (german) only shows Pixels per Cm and that was kinda confusing well, I checked on it and I got around 100 dpi at the size, I would like it to be printed, but even though this seems okay, my m8 said it wouldn't work out... but maybe he's just a little overreacting - used to perfect stuff? Ofc most of the people, wanting their pics have printed out HUGE are some kind of firms, etc...

however, I'll just try it that way, we'll see but thx everybody for your help

You can change it to show per inch or centimetre or whatever quite easily.
Most people that want massive prints also work from large format film, look at this photo for an example, the small slide is the same size as an FX sensor.



Obviously, working from a bigger slide/sensor/negative/whatever allows you to get a larger sized final image.
