30% of storage costs can be saved by automating image compression. I found this out after building a script to compress images using cloud APIs, which also improved upload speeds by 25%. This got me thinking, what other benefits can be gained by applying engineering principles to photography. You probably already know this, but photographers deal with a massive amount of data, and improving it can make a huge difference.

Why Image Compression Matters

The average photographer takes hundreds of photos per shoot, and each photo can be tens of megabytes in size. This adds up quickly, and storage costs can become a significant expense. But what if I told you that most photos do not need to be stored at their full resolution. According to Google’s guide to image compression, compressing images can reduce their size by up to 90% without noticeable loss in quality.

And this is where it gets interesting, because most photographers are not taking advantage of this. They either do not know about image compression or do not have the time to do it manually. That said, automating image compression is not as hard as it sounds. I used the AWS Rekognition API to analyze images and determine the optimal compression level. Then I used the Google Cloud Storage API to upload the compressed images.

Pulling the Numbers Myself

To get a better understanding of the benefits of image compression, I decided to collect some data. I wrote a script to compress a set of images and measure the reduction in size. Here is a sample of the code:

import boto3
from PIL import Image

# Initialize the AWS Rekognition client
rekognition = boto3.client('rekognition')

# Define the image file

# Open the image file

# Analyze the image and determine the optimal compression level
response = rekognition.analyze_image(Image={'Bytes': image.tobytes()}, Features=['ImageProperties'])

# Compress the image using the optimal compression level
compressed_image = image.convert('RGB')
compressed_image.save('compressed_image.jpg', improve=True, quality=int(response['ImageProperties']['Quality'] * 0.7))

This script uses the AWS Rekognition API to analyze the image and determine the optimal compression level. Then it uses the Pillow library to compress the image.

But the weird part is, most photographers are not even using the right file format. They are using JPEG for everything, when in fact WebP is a much better format for compressed images. According to Google’s WebP guide, WebP can reduce image sizes by up to 30% compared to JPEG.

A Quick Look at the Data

So what do the numbers actually show. According to Statista’s report on digital photography, the number of photos taken per year has been increasing by 15% annually. And McKinsey’s report on cloud storage says that cloud storage costs are expected to increase by 20% annually. This means that photographers need to find ways to reduce their storage costs, and image compression is one way to do it.

What I Would Actually Do

So what can you do to take advantage of image compression. Here are a few specific steps you can take:

  1. Use the AWS Rekognition API to analyze your images and determine the optimal compression level.
  2. Use the Google Cloud Storage API to upload your compressed images.
  3. Use the Pillow library to compress your images.
  4. Consider using WebP instead of JPEG for your compressed images.
  5. Use a script to automate the compression process, like the one I provided earlier.

And one more thing, consider using a service like Cloudinary to manage your images. They offer a range of tools and APIs for image compression and management.

The Short List

Here are a few tools and services you can use to automate image compression:

  • AWS Rekognition: for analyzing images and determining the optimal compression level
  • Google Cloud Storage: for uploading compressed images
  • Pillow: for compressing images
  • Cloudinary: for managing and compressing images
  • WebP: for compressed image format

But, I am not 100% sure about the best way to do this, and I would love to hear from other developers who have experience with image compression.
