Photo prints - How large can I print my photos?
Photo quality is the most common concern for printing personal photos into posters.There are many issues which affect your photos taken by camera, pads or phones. Old fashion concepts of resolution and image quality have become outdated and more complicated to quantify. Modern photography is a vast galaxy of variations, all of which bear an affect on your image. Many factors contribute to how good your photo will print.
Photo quality is partially based on pixels and can vary enormously between different cameras and phones.For instance, iPhones generally take very high quality panoramic images, with an amazing number of pixels per inch. However, their standard, non-panoramic images are sometimes not as packed with pixels. One of the first items to check when taking photos is the settings on your camera. Cameras often arrive with a selection of pixel settings from high resolution down to low resolution. The reasoning behind this is simple. If you plan to post your images on social image sites such as Instagram or Facebook, then a large number of pixels is not required.
Social media sites generally reduce the size of your image when you upload it. This is desirable for people utilising social media as it keeps the viewing of images within a reasonable download time, which means viewers do not have to wait for ages and ages whilst an images makes its way to their computer or phone. Sharing images becomes much easier as users using social media can be confident that any images they wish to share will easily find their way to the intended recipient. The other advantage of reduced image sizes, is storage.
One thing to check before using a new device:
When you purchase a new camera or phone that you intend to use for photography, it is always a good idea to check the resolution settings. Most cameras will let you set your images to a higher quality. Factory default settings tend to conserve storage space so that you can take the maximum number of images. However, if you may wish to create high quality poster prints, canvas prints or photo framing from your photography then its a good idea to set the resolution as high as possible. Its better to be safe then sorry! You can always delete undesirable images or transfer photos onto your pc.
Jpeg is a form of compression used to store image data. Photo compression is a technique used by cameras, phones & social media.This is a method of reducing the data within the image in order to reduce the file size. With compression techniques, the number of pixels may remain the same, however the quality of the pixel date can become extremely compromised. An image that requires 5 or 10Mb of storage space can keep the same number of pixels and yet when compressed, needs only 1 or 2Mb of storage space on your computer or camera. Its not rocket science to guess what sort of affect this will have on the quality of your photo.
There are two basic things which become compromised; colour and the quality of the pixels. By reducing the number of colours contained within an image, there is much less data to be kept. For instance a black and white image containing the same number of pixels as a colour image will require about 25% of the data. This affect may not be noticeable when viewed on a screen but is very evident when printed.
Compression comes in many levels, from high quality that will barely damage the photo and is still suitable for print to heavy compression (often used by websites and social media), which removes most of the detail and colour from a photo. For this reason, we also suggest that you upload the original file from your phone or cameras. For best results, you should always print from photos as they were taken, unadjusted and uncompressed. We will always endeavour to ensure that your images are printed at their best, even if we need to lighten some of the darker areas or brighten the overall image.
Noise is the bane of all photos taken in limited lighting conditions.Often, when you view a photo of a night-time sky full of stars, all you see is a wave of tiny dots containing red, green and blue. This is known as ‘noise’ and is inherent in all digital photography where the lighting is limited. Basically, the colours of the image break apart into tiny dots whilst the camera struggles to find enough light to render the image. Essentially there is nothing that can be done to prevent this from happening to some degree.
Professional photographers use various techniques to reduce the level of noise although this is a complicated methodology and requires knowledge and experience.
For those of you with digital SLR cameras, all of the above three points get far more complicated. The quality of your digital chip, coupled with resolution, lens quality, and camera software add an even greater degree of variation to the results of your photography.
Never fear, today’s digital devices take amazing pictures for print.
