I am frequently sent phone pictures by friends and family that they would like me to print. My Epson printer recommended resolution is 360ppi. Recently my friend sent me a picture that appeared would be too small to print at the 8 x 10 size that she wanted. She told me that her husband had printed it on their home printer on regular paper at 8 x 10 and it looked fine. I told her I would give it a try and was pleasantly surprised at the outcome. I converted it to a smart object and used Janice’s tip and clipped the pictures to an 8 x 10 rectangle. If anyone knows why this worked, please let me know. I thought I would share this in case it might help someone else. Pictures are intentionally blurred as I wasn't comfortable showing the actual picture but felt an example would be helpful.   It also allowed me to print 25 miniscule phone pix at approximately 4x6 today (using the same process....converting to a smart object and clipping to a 4 x 6 rectangle. without using Gigapixel.. |

Welcome to the wonderful world of smart objects. Unlike rasterized or pixel based layers, a smart object is a container that protects the image and enables you to resize without impacting image quality - to some extent. The example shown had the same pixel width and height along with file size and resolution at the end.  |

Thanks Helen and Frank.
I'm living in the dark ages. Must learn about smart objects.
Someone took photos of me yesterday and texted them. Ugh, they are small. I tried resizing as SOs but could see no appreciable difference.
Need to study this more.

Thanks, fotofrank. I was hoping you would see this and thought you would be able to explain it. Quite amazing to me.....and will save me a lot of time going forward! pontiac1940, when once converted to a smart object and clipped to the rectangle, I used the free transform tool to make it fit. |

That you saw no appreciable difference by using smart objects is to be expected. It is often repeated that you can resize smart objects without loss of quality but that is not true. The difference between a SO and a regular image is that after doing an edit on a regular image the original is replaced with the edited version, whereas with a SO the original is retained.
If you resize an image to make is smaller, then do another resize to enlarge it, with a regular image the last enlargement will have less detail because the starting image was the smaller one. If you were working with a SO to begin with, the enlargement resize is derived from the original, which gives the impression that the SO allowed you to enlarge an image without losing detail.
However, as you found, if you simply enlarge an image to the point that you can see the loss of detail, it doesn't matter if you started with a SO or not, the results will be the same.
This article is pretty good at explaining the benefits of smart object. |

Tpgettys Tom, thank you for the explanation. Makes me feel better. Maybe I need to learn more come next winter. I take so many photos I barely have time to edit them with the basic adjustments: levels, contrast, etc. I still haven't looked at 300 osprey photos from last week. This morning, I had to go to the local post office...well there were two (spooky) great blue herons on the ponds as I drove by. Then at home there was a giant female polyphemus moth in our yard. Between the two subjects ... almost 300 photos. Lots of fun. Thanks again! Clive

You're welcome Clive. I am quite envious of the wealth of subjects in your neck of the woods! ...but then again I don't envy you the task of dealing with so much!
