![]() We showed the users 200 different image pairs, with a resolution ranging from 2500 pixels to 12 Megapixels, at 100% zoom (“Actual Size”). The viewing tests were conducted in controlled lighting conditions, with calibrated monitors placed in front of a gray-colored wall. This is how the tests were carried out: We took a group of 23 people (the standard mandates at least 15), and tested them for 20/20 vision and for correct color vision. What these tests have shown is that the original JPEG photo and the optimized JPEGmini photo cannot be distinguished by average users when displayed at 100% zoom on a computer monitor, or when printed at 200 DPI or more on photo paper. To make sure that JPEGmini does not harm perceived image quality, we’ve conducted subjective tests with real human viewers, according to the strict specifications of the ITU BT.500 standard. That’s how we are able to achieve an extremely high reduction in file size without harming the photo quality. The second is a unique JPEG encoder, which adapts the JPEG encoding process to the original photos, creating the most compact representation of the photos that is possible under the JPEG standard. The image quality detector imitates the perceptual qualities of the human visual system, to determine the maximum amount of compression, which can be applied to each photo without causing any visible artifacts. How can we compress without introducing any visual artifacts? Well, it’s all in our magic sauce, which comes in two main components. This is how we make sure that each photo is compressed to the maximum extent possible by removing redundancies, without creating any visual artifacts in the process. We developed an algorithm that imitates the perceptual qualities of the human visual system. We decided to take JPEGs, which have been around for many years, and decided to make it more user friendly for the modern world using sophisticated metrics and tools. So how can you maintain photo quality while keeping the file size small? Well, we took that question and went to work. Jalai Lama April 15, just reduced my website loading time by 50%, with ~0 quality loss. Just increased page loading time on & reduced image size 20%, without compromising quality w/ In 2015, if your website is loading slowly, your visitors will go somewhere else. If the photo file sizes are too big, your website will load slowly. Smaller photo file sizes are a big deal for websites too. With smaller file sizes you’ll be able to send more photos to your client via email or maximize the space on a flash drive. ![]() ![]() You’re exporting the JPEG under 90% because you want your photo file size to be smaller for various reasons. Why aren’t you exporting your photos at 90% or even 100%? Simple reason is file size. Should you choose save for web? Or do you set the JPEG quality slide bar under 90%? However, it’s with these tools that you can manipulate the photos as you see fit.Īt the end of every editing process, you are posed with a question on how should you set your JPEG export settings. No matter what tool you use, you know that this is going to be time consuming. Once the photo selection is over, we get straight to work on editing the photos we’ve singled out. We want to make sure we give our clients the best of the best! Blurry photos, bad lighting, centering, and even closed eyes won’t make the cut. Photo quality is the reason why we don’t just go straight to printing right after a shoot. I won’t go in as to why it’s important, since every reason is correct. Yes, I know this is a rhetorical question because photo quality is very important to all of us. If I were to ask you, on a scale of 1-10, how important is photo quality to you? You would most likely answer me 11. Photographers stake their reputation on photo quality.
