We know that having a photo printed makes it that extra special! Your precious photo can be admired in your home and not stuck on your phone or a Facebook album. Most smartphones come with impressive cameras, that can produce some high-quality images, but how can we find out how these images will translate to print? We have developed some rough tips to help you turn those images into the photo print you desire! Images shown in this guide are simulated to demonstrate how the image will vary.
What is a high quality photo?
We don't want to get too technical here because, let's face it, not all of us are budding photographers! The easiest way to explain high-quality photos is with examples. If you have ever tried to print an image that you downloaded from Facebook or Instagram, you may have noticed that not every photo prints out as expected. It's an easy mistake to make as what looks good on your smartphone or screen might look blurry or pixelated when blown up to a larger size. This distortion occurs when there is a resolution issue. Every image or photo has a resolution. It's just the number of pixels it is wide, multiplied by the number of pixels it is tall.
NOTE: When we talk about our "examples", we are not referring to photos that are taken in low light or out of focus. Photos with these conditions, will not adhere to these same rules and will most likely result in a low-quality photo print no matter what!
We have tried to demonstrate how some versions of popular smartphones behave when taking a photo on standard settings. Unfortunately, we cannot provide all examples of smartphones (it would be a big graph trust us!)
NOTE: This diagram is a guide only. The guide demonstrates photos taken on the same device, not one sent or downloaded from social media or other sources. Downloading images will distort the original image's resolution.
Working out how your photo will print
Let's see how this all translates into photo quality. For this example, we will use an image taken from an iPhone 6s (Left) then compare it to when it is blown up by 50% (Middle) and 125% (Right).
Let's take a closer look.. When this photo is uploaded to a medium-sized photo on our Popic posters, our system will blow it up to around 50% of its original pixel size. If you upload it to a larger-sized photo on our Popic posters, our system will blow it up to around 125% of its original pixel size.
NOTE: This is only a rough guide on how your image will be scaled as photo sizes on our products vary; we cannot provide specific examples. We recommend that you use this guide with your device or image pixel calculations and base it on a 125% scaled-up image as a maximum to ensure high-quality photo reproduction.
Calculating the pixels of your image
So let's calculate your photos, as we understand not everyone has an iPhone 6s, right? If you want to calculate your smartphone's maximum high-resolution print size, divide your image's horizontal and vertical pixels by 300.
So, for example, an image taken on the iPhone 6s has a 12-megapixel camera. That means any photo taken with it will be 4032px by 3024px. (See Our Smartphone Guide). Take these numbers and then divide them by 300, and you get 13.44 inches (34.13cm) wide by 10.08 inches (25.60cm), which is almost an A4 size which is a very decent larger size!
Note: The calculations are based on inches, as this is the standard measurement conversion for pixels (px) and guides. If you want to convert this into the metric measurement, multiply it by 2.54 to give you the cm size.
For example 13.44 inches x 2.54 = 34.13cm
Cropping a part of your image
What if you only want a specific part of your image printed? Our system will let you crop your photos, so let's go through how this will affect your high-resolution photo. Let's take our image from our iPhone 6s (4032 px by 3024px) and crop a portion of it.
Let's see a cropped image in our poster. Again our system will behave the same way as our first example. When the cropped photo is uploaded to a medium-sized photo on our Popic posters, our system will blow it up to around 50% of its cropped pixel size and on the larger-sized picture around 125% of its cropped pixel size. You can see that the image does become a little less clear. So it is important to understand that you must now work to the new crop sized measurements and complete the pixel calculations accordingly.
Try to avoid over cropping a photo. Cropping is a great tool, and when used correctly can make sure you get the perfect photo. A great tip when cropping an image is to remember to try to crop it evenly from all sides.
When cropping goes wrong
It's best practice to avoid cropping in too closely on a particular photo area, especially if it is shot from a distance.
In this example, you can see we have cropped in very closely to this woman's face. We have then used this example and uploaded it to a larger-sized photo on our Popic posters. Our system will blow it up to around 125% of its cropped pixel size. This will result in a very pixelated and low-quality photo print—something we certainly want to avoid.
Now you're a pro, have fun creating your unique personalised products for the ones you love. It is important to note that you will always impact your photo's resolution whenever you resize the original version. So, the less you do to it, the better result you will achieve! Just remember, you will not be viewing your photos as closely as you do on a screen. You will admire them from a distance, hopefully for years to come.
Our pre-set minimum requirements.
We want to make sure that your personalised print is of the highest quality; therefore, we have set the minimum requirements of your photos uploaded to 1000px by 1000px. If your image doesn't meet this minimum requirement, a warning will appear.
Did you see this warning? - Let's Explain...
If you see this warning, our system will prevent you from using this photo. We have set this restriction as we cannot guarantee your product's quality, and we want to produce the very best for you. You will need to upload another photo or a higher quality version of that same photo.
