I was thinking of getting one of my photos on a canvas, but they are saying low resolutions so my question is if this it a way of them making more money or what must I do to increase my picture resolution

Need more info...what camera, how big are you wanting it???

Looks like a nice image.

Here is a pretty good calculator that relates print size, viewing distance, and pixels per inch.

If you have Photoshop or similar you can try to resample, otherwise reduce the print size to something more similar to the numbers in the calculator.

If you are viewing at arms length or father you don't need as much resolution, if you are planning to be only a foot away then you would need more.

Thank you for the website information. It helped me too!

One time printing a calendar ( 11x14 ), the vendor complained about the resolution.
I was puzzled since I was sending him pixel shifted full frame images which have large file sizes.
Finally got it worked out - their system took the large file sizes as "too small".
When I finally got the calendar - was fantastic!

We don't know the size of the print nor the size of the image so we can't say if there is enough resolution. For canvas of a given size you need less resolution than a for example a high gloss image of the same size. No it's not a way for them to make money in fact they lost 1 sale to you. Without knowing what your image resolution is and how you get it it's difficult to say how to improve the resolution.

It would have been better to have attached and stored your image file. Then, we could inspect the file size ourselves instead of continuing to guess or hold an ongoing Q&A.

Regarding printing of pixel-based images, the process is relatively simple: seek to have a file that calculates to 300 pixels per inch (ppi), based on the intended print-size as measured in inches and the pixel resolution of the image file. As your print size gets larger and larger, say larger than 15in x 10in, this 300ppi 'gold standard' becomes less important where values down to 150ppi still yield excellent printed results.

Example: if the image file is 3000px by 2000px, a print at 300ppi is 10in by 6.7in. This same image at 200ppi would yield 15x10-inches. This issue with lower ppi for small files is you can hold the print / frame in your hand and look closely at the details and still see the entire image. For ever larger prints, you will see them on the wall, where you're standing back from the print to see the entire image, not nose to frame of the print looking at the fine details. For today's 'mega' megapixel cameras, they can yield large prints with amazing fine details of 300ppi for prints like 30in x 20in.

So, if you had attached the file, we could calculate the PPI and give you the reasonable (max) print sizes based on the pixel resolution of the file, at various ppi ratios.

I crop everything I print on my Epson 7900 at the size I want at 300 dpi. No issues.

What are the dimensions in pixels and how large is the finish image size going to be?

If your image will be 11x14, then 156 ppi will be enough for the perception of sharpness at 27" viewing distance.

This explains the relationship between ppi, viewing distance and to some degree paper choice.

If printing on canvas, you can get a sharp looking print with even fewer ppi.

Not a way of making them more money. Just making you more happy with the result.

In a sense, it could help them make more money from a repeat customer who ends up liking the result better and buys more. This is the main premise of capitalism, by the way.

It always amazes me that we get these questions and the OP doesn't provide an example with EXIF not stripped, not even the next day.
