QUESTION: Dear Kevin Stohlmeyer!

I am really very new to Photoshop and I know s.th little about it because I rarely use it except when I need to covert the color to be used in CYMK Mode for another application, but now I start it and intended to know more. I hope you will help me with this problem. I have taken a photo containing 72 PPI and the size is 35.2 x 26.5 cm. I drag it to my file containing 300 PPI (A4 Side), but the photo becomes smaller here. Let me know what makes it small here. Please tell me how to keep the photo as good quality as the original photo. I really don't know how to figure it out and just do it for present uses or for a short time though it's small.

Hope you will understand what I mean here and please help help...

All your explanations and techniques are very useful to me and others and it's the best chance.

Yours sincerely,

ANSWER: Hi Touch,


The different size is caused by the resolution. You are bringing a smaller resolution image into a larger one, so the size is comparably different. To keep the size the same, you would either have to drag into another 72 dpi image or your Image>Image Size to change the 72 dpi file to 300 dpi. However, when you increase the resolution, your physical size (W + H) will reduce to keep the file in tact.

Let me know if you need help with making this file larger. It will damage this image though, making it appear bitmapped or blurry when you increase the resolution. A better solution is to find a larger image or take another photo at a higher resolution.

Thanks

QUESTION: Hi, Dear Kevin Stohlmeyer!

I need help with making this file larger. I don't know how to take a photo with higher than 72 dpi because most of the digital cameras are produced with 72 dpi, I noted. Could I have any programs or plug-ins for making a higher resolution and keep the same size as it is in 72 pdi? If so, would you mind offering me?

Thanks a lot for paying attentions to my questions and best wishes to you!

Yours sincerely,

Answer
Hi Touch,

If you open your digital camera file and go to Image>Image size in Photoshop, you can see the original size. Next, uncheck the "Resample Image" box at the bottom of the dialog box. Then enter your higher resolution. The image will change in size to match the resolution. Then recheck "Resample" and choose "Bicubic Smoother" if you are going to increase the W & H. Change those two as needed and then hit ok. The results will be a larger file. If you are increasing significantly, the image will degrade. Choose the highest quality camera settings to avoid this as much as possible.


Thanks
