Can someone tell me how to resize the standard 35mm sized photos to medium format sized photos? without the distortion?

Thanks

Try genuine fractals. It really works.

It is a photoshop plug in

your post is vague -
Since you mentioned distortion, do you mean from the more rectangular format of 35mm to the more standard print format of medium format? 6x7?
You said medium format and 2.25 square is considered medium format. So still confused as to what you're asking.

When you resize - keep perspective the same. (usually a software option / check box)

When I need to print a D30 image in a 8x10 or 30x40 etc. I can either crop the top and bottom to make the perspective correct... or when making larger prints I increase the canvas size on the sides of the image (rather than cropping data I add It.) After I increase the canvas, I copy/paste dupe in more of the background where the canvas as been increased.
I find I do this the most, since I don't like hacking away at the composition.

Personally I don't care for Genuine Fractals. It gives the images a fake painted look. Photoshop upsampling by itself works best and gives the most real photo quality results. But I'm not sure if your original question is asking about upsampling or keeping proportions.

Thanks for the tips. Sorry I was so vague... I was talking about the normal 35mm rectangle's to the nicer looking square format.
Yeah I think $150 for a plug in for a $600 program is a bit much just to resize something... and I also dont like what MOST of these digital picture sites are producing. They look too altered. I've seen some beautiful photos that just look fake as can be. Expecially the sharpen tool. Most people need to just put that thing away and never use it.... ever! Most of these people have nice L series lenses, tripods, the whole nine yards... a clear picture shouldnt be too hard to get. ;) IMHO

Thanks again guys

Doug,

I have done some testing with upsizing, which I have written up on my site:

http://www.rogercavanagh.com/tips/t04_upsizing.htm

In a nutshell, a lot will depend on the degree of magnification you are after. Genuine Fractals _does_ work for high mag - I have tested 8x - but some people like the previous poster don't like the "painterly" effect. Others are very happy.

Photoshop's bicubic does work, but I think you get better results by upsizing in increments. Have a look here:

Also PS upsizes _much_ better with 16-bit images than with 8-bit as you will see, if you read my piece.

Hope this is some help.

Regards,

Roger

You will need to crop you photo to the proportion wanted.

Wow, I just read the reply above and tested out Freds enlarning process. I can't believe There is a program that works better than Genuine Fractals. Seeing is believing, I just tested a file of my own and was blown away. You did it again Fred
