How to download ultra high-res images of works from Google Arts and Culture

I wanted a framed print of The Lady with an Ermine when we were redesigning our workspace during lockdown. Important works such as this painting by Leonardo da Vinci usually have high-resolution images online. The typical sources are Wikimedia Commons and Google Arts and Culture.

The Lady with an Ermine has a high resolution copy on Wikimedia but the highest version only has a dimension of 2,048 pixels × 2,754 pixels. That is good enough for print but I wanted an even higher resolution.

There’s one in Google Arts and Culture – a zoomable version with ultra-high resolution that will allow you to focus on minor details of the work. The only problem is you can’t directly download images from the site. There are some works that you can download, such as those made publicly available by The Metropolitan Museum of Art, but most images you can’t.

To be able to download images from Google Arts and Culture, you can run a script such as Dezoomify. It has a web version and even a browser extension but I prefer the script. What Dezoomify does is download the maximum resolution of an image by getting it by tiles, which are the portions shown when zooming, and then reassembling it to its full quality.

If you download the script, all you need to do is run it, paste the address of the Google Arts and Culture image you want to download, choose the image resolution, and it takes care of the entire process. With The Lady with an Ermine, for example, the script took 5,002 tiles to download a 30,894 pixels x 41,545 pixels JPEG image with a total file size of 114 mb.

DOWNLOAD WITH SCRIPT. If you run the Dezoomify program, it will ask you to paste the URL of the file you want to download, pick a resolution, and then it does all the rest.

According to its project page, Dezoomify also works with other online resources such as the National Gallery of Art, Harvard Library, The British Library, among others. But I’ve only been able to try it with Google Arts and Culture and its vast collection.

ULTRA-HIGH RESOLUTION. The script was able to download a version of The Lady with an Ermine with a resolution of 30,894 pixels x 41,545 pixels - a JPEG file with a total file size of 114 mb.

Running a photo contest? Do a reverse image search!

The grand prize winner of Globe’s Picture Perfect 2.0 has been accused of submitting an image from a stock photo site for his winning entry.

Charles Chamberlaine Igot won the grand prize for his entry “Sunset Catcher.” Igot, who has since deactivated his Facebook account, posted photos on March 6, 2020 when he got his prize: P50,000 and a trophy.

It turned out that the winning photo was actually taken by Vietnamese photographer Quang Nguyen Vinh. According to the image information, it was of fishermen in Phu Yen province in Vietnam. The photograph, which was taken in 2017, is available for free download and use in various stock photo sites such as Pexel.

It’s an embarrassing turn of events. Organizers of the contest, however, could have avoided it by performing a simple reverse image search. For the unfamiliar, a reverse image search is when you upload a photo and a search engine like Google then scours the web to check if it has been used elsewhere and on which sites.

When you do a reverse image search using the grand prize photo featured in Globe’s website, you’d see that it has been used as stock photo in many websites, including Philippine sites. To do a reverse image search, you just download the photo in question and upload it to Google (click on image search). On Chrome it’s much simpler: you just right click on the photo and choose “Search Google for image” in the menu.

USED IN MANY SITES. A reverse image search shows that the winning photo was in fact used in many websites, indicating a high likelihood of being a stock image.

Igot was recently in the spotlight when his prenup photos of a couple in a muddy paddy went viral after being shared by several social media accounts of news organizations. Here, here, and here. (It seems pre-nup photos are a reporting beat now in newsrooms.)

NO THANKS. Generous photographers like Quang Nguyen Vinh allow people to use their beautiful images for free and often without a photo credit or backlink.

Going Off the Grid: Breaking the Rule of Thirds

I won’t start with the cliché that “rules are meant to be broken”, but I’m pretty sure that more than a few photography enthusiasts would agree with me when I say that the well-known Rule of Thirds doesn’t really work all the time.

For the benefit of the uninitiated, the Rule of Thirds is a popular composition guideline for photography and design, where you’re asked to visualize your image as divided into nine equal parts, pretty much like the one shown below:

Thirds

The Rule says that the prominent elements of your picture must be placed along the lines, or intersections in the grid. Below is an image that more or less follows the said rule:

Works pretty well in the photo above, right? The prominent element is placed on the lower left intersection while the horizon is aligned with the upper-horizontal line of the imaginary grid. However, more experienced photographers may actually consider the Rule of Thirds as more of a guideline than an actual rule. There are some instances when shots would look better (and actually make more sense) when this composition guideline isn’t followed.

Portraits

As seen in the example above, portrait shots show more emphasis and simplicity to the subject when it’s positioned at the dead center of the image. Much more when there are a lot of things going on in the background and you want to set the subject as the center of focus of the viewer.

Prominent Horizontal Lines

Horizontal lines in pictures (like horizons, for example), are easiest to position to follow the Rule of Thirds. Doing so adds more depth and dimension to an image.

However, positioning the horizontal line at the dead center of the image also creates an effect of balance, and gives equal emphasis on both upper and lower halves of the picture. Check out the image below, where positioning the horizon at the center of the image equally shows the beauty of the sky above and the body of water under.

Symmetry

Sometimes you get shots that are beautifully symmetrical on both right and left sides, that it just feels wrong if you’re going to ruin the balance. Take for example the image below:

Thirds6

 Seeing that the lines in the image are balanced well on both left and right sides, it wouldn’t feel right to place the subject off-center. When you can see that your subject is in almost perfect symmetry, it may create more impact when the object of interest is placed at the center of the frame.

Night Sky and Star Trail Shots

Let’s say you have this really awesome shot of the Milky Way – you’d definitely want to feature more the sky and less of the landscape in the frame, right?

In star trail and night sky shots like the one above, it only makes sense for you to move the horizon even lower to feature more of the sky. It also creates the impression of vastness of the night sky.

Under the right circumstances (and with enough skill), breaking the Rule of Thirds may actually make your shot more interesting and less predictable. But this doesn’t mean that you go ditch the Rule altogether and breaki it every chance that you get. Experimenting with composition is nice, but it’s a double-edged sword that can either make or break your shot.
