Pic Vs. Banner Canvas

[forgedground]

Hello my friends....

This is my first post, but i have a huge headache and cant get it go for the time beeing.....

First of all....IM A NEWBIE, so please just......help me out if you can........thank you in advance


So.....my issue is :

I do custom banners and my project file for large scale is : 8268pxs vs 16570pxs or 70cms x 140.30cms....thats my normal canvas.

Mostly peeps send me like a 6000pxs vs 4000pxs image.....

When i "upscale it" or resize it to the values i need....it looks horrible.......

What can i do to a regular pic and resize it to the size i really need without the loss of quality?

Thx in advance


Specs :
1) Mobile Samsung S20
2) Canon 2000D
3) Photoshop CS6

Hi @forgedground
Any chance you could share an example image even at lower resolution. Depending on the type of image, there are a variety or approaches.
- There are upsizing programs such as Topaz GigaPixel AI that does a pretty good job and enlarging some types of images
- If these are banners without a ton of detail, the potentially could be converted to Vector format and then increased in size in vector form before printing

Any more details you can provide will help forum members better target their recommendations for you.
Just a suggestion

@thebestcpu has given some good advice. Gigapixel is probably to best software for upsizing your images. His other suggestion, depending on your design, would be to pull it into Illustrator, trace it, and resave it in vector format.

I have used some online image enlargers with some luck - cant guarantee it on all images. But you try them at:

AI Image Enlarger | Enlarge Image Without Losing Quality!

AI Image Enlarger is a FREE online image enlarger that could upscale and enhance small images automatically. Make jpg/png pictures big without losing quality.

imglarger.com

Bigjpg - AI Super-Resolution lossless image enlarging / upscaling tool using Deep Convolutional Neural Networks

Bigjpg - Image Super-Resolution for Anime-style artworks using the Deep Convolutional Neural Networks without quality loss. Photos are also supported.

There's a limit on how large you can upsize free - go larger and there's a fee. I would warn though they can generate artifacts but again, depends on the artwork.

It would be a great help to see a sample - possibly even just a section for play or a downsized version to consider options. I've worked on convention panels that went upwards of 9 ft. long and we generally generated files at 1/2 size at a resolution of 150ppi. How the banner will be viewed generally determined how we would produce the final file.

Hello thebestcpu and JeffK

First of all, thank you for the kind answers

Let me explain with 2 examples.....tha banner can be Graphic Images wich i can vectorize and resizing with no problem at all.....but i offer a personalized option too....wich is uploading your own image and make the banner....

I always tell people i need a very big and HD quality image, but even with my own camara i cant go more than 6000x4000pxs wich in the case of the banner it should be 8268pxs vs 16570pxs

Attached is a JPEG picture with 6000x4000pxs and an example of the size of the banner (black canvas) with the image on it : 8268pxs vs 16570pxs




I upscaled the image for the banner size and the second foto is the quality at 100% scale

Thx

1) If your canvas has 8268x16570px, then your image with a size of 4000x6000px should look like the red section - otherwise you are doing something wrong.


2) Why do you think you need such high image sizes?
Your print resolution depends on the desired image size and viewing distance. An image with 8268x16570px, printed at 70x140cm with ~300ppi you need a viewing distance less than 19cm to identify the individual pixels. Do you really need such an short viewing distance?

An image with ~6000x3000px, printed at 70x140cm with ~110ppi you need a viewing distance less than 50cm to identify the individual pixels.

Du wolltest immer schon etwas über dpi / ppi /cm / px und deren Zusammenhang wissen? Hier findest du die Antworten und kannst alles berechnen lassen.

3) If you really need such huge images, then use 4 or more photos and stitch them together... you can make them by hand or an panoramic head/nodal point adapter (to prevent the paralax problem)

Hi @forgedground
I agree with @[ iLLuSioN ] that you should not need 300ppi unless you are viewing from about 12 inches away.
For a banner, 150 ppi should normally be just fine.
That said, there are some customers that view the end product up close looking for details so that is hard to control.

I will assume you have a general issue of not having high enough resolution images that you need to enlarge.

Depending on the issue there are a number or approaches to enlarge and get reasonable results (don't expect miracles though)
- Topaz Gigapixle
- Topaz AI Sharpen
-Topaz AI DeNoise

Yet a simple approach without any extra software is just enhance in Photoshop.
I took your 100% image and applied the Adobe Camera Raw Filter with increased Clarity, Texture, Sharpness, slight reduction in highlights and a bit of Noise reduction. The did an adjustment brush of similar settings for just the eyes, eyebrows, and nostrils.
The before and after is shown in a GIF animation below.
Hope this gives you some alternatives to consider.
