How To Enlarge Images ?

Is there any way to enlarge images without loosing the quality or picelated. I heard that there are software/tools to do that but I am not sure.

 

I have heard it too but could not find it so far.

 

I actually googled it and found some articles but they were old posts and couldn't find an efficient way

 

Use adobe photoshop. Increase image size + resolution.
I think it will work as best for you.

 

Yes you can use adobe photoshop or corel paint shop pro,
but you also need to pay attention at the algorithm used
to change image size.

With photoshop you need to choose "bicubic" for best
enlarging performance, while in paint shop pro, "smart size"
would be your best choice.

Anyway, no matter what tool / algorithm you use, you can't
get a larger picture at the original picture's quality. Yes
there are ways of smoothing the edges, interpolating colors,
etc., but the amount of information comprised by the picture
itself cannot be increased, so the quality of the enlarged
image will be at most the same as the original.

 

photoshop is the best tool..just increase the image's resolution.

 

ill go a lil deeper in this topic.

you have to look at it this way. ONE pixel has ONE information and that is ONE color code. If you have a small image and just increase the size by lets say 4 times. That ONE pixle becomes 4 with the same color info.
now here is what the programs do: lets say you have 2 pixels: one blue and one yellow. you have made it bigger and now you have blue blue yellow yellow. you grab the programm and now you have blue Mixed mixed yellow.
get it?
thats why it will result in a more blurred img when you increase the size.

I dont have proof for my theory but that is what i think happens.

-dyna!
hit em up for DOPE graphics!

 

Dyna has it - you can't add information where none exists, you can just make an educated guess and that just blurs instead of pixelating.
If you can get the original hi-res image you can work with it but not with low-res. There are image enhancing programmes which (for instance) the police use for grainy CCTV images, but they amalgamate data from several frames. No data, no image.

 

Hi the best thing to use is photoshop i one way would be to turn the image into a smart object but you will need to implement other techniques depending on how far you want to scale them.

 

Hi photoshop is the best... I my self have used it for printing mega size banners... Keep the resolution high...

 

Even if you do this you are still goint to lose a certain degree of pixel quality, obviously the larger size you re-size it to the more you will notice, chaging the resolution helps but does not stop you from losing quality.
