1. Find images that are often published

2. Find images which meaning has changed over time

3. Lessons learned

4. Hopes for the future

1. Often published

7

• Which identical photos are published most often?

• 400 Dutch History textbooks

• Dataset of ~ 5.000 photographs

• Analyzed on 41 variables (f.e. name person & topic)

• IPTC to structure dataset

Advantages for photographers:

- Code multiple images at once

- All information in 1 file- All software can read

information in the file- Easy to transfer

Advantages for academics:

- Code multiple images at once

- All information in 1 file- All software can read

information in the file- Easy to transfer (& share)

- Find images easier- Export all data

1. Often published – My case

12

• Which photos are published most often in 400 Dutch History textbooks?

• Locate photos in History textbooks

• Digitize them & add them to Fotostation Pro

• Code all images & add values in IPTC fields

1. Often published – My case

15

• Export data variables (f.e. topics) to SPSS

• Create frequency lists topics

• Which topics are most frequent?

• Manually go over most frequent topics to find most published photographs

2. Changing Meaning

• Back to Fotostation Pro to easily find photographs of Troelstra:

• Go over the captions provided in the history textbooks

1912?

or

1918?

Page 20: Tracing the afterlife of iconic photographs using IPTC

3. Lessons Learned

20

• IPTC was useful & efficient

• Manual labor remained necessary & typos will happen

• Does the most frequent topic also contain the most published identical photo?(Spoiler alert: NO! )

• How to describe photographs?Do we all see the same thing in images?Do we all use the same words to describe images?

Page 21: Tracing the afterlife of iconic photographs using IPTC

“Universal suffrage, Portrait”

Page 22: Tracing the afterlife of iconic photographs using IPTC

“Political parties, social-democracy the Netherlands”

Page 23: Tracing the afterlife of iconic photographs using IPTC

“Protestphoto”

Page 24: Tracing the afterlife of iconic photographs using IPTC

3. Lessons Learned

24

• IPTC was useful & efficient

• Manual labor remained necessary & typos will happen

• But does the most frequent topic also contain the most published identical photo?(Spoiler alert: NO! )

• How to describe photographs?Do we all see the same thing in images?Do we all use the same words to describe images?

• Semantic Gap

Page 25: Tracing the afterlife of iconic photographs using IPTC

3. Lessons learned

25

“The semantic gap characterizes the

difference between two descriptions of an

object by different linguistic

representations, for instance languages or

symbols.”

Smeulders, 2000

4. Hopes for the future

26

• How to overcome or avoid the semantic gap?

• Image recognition

4. Hopes for the future

Let me create my dataset of photos (with IPTC)

Apply image recognition to: Show me similar photos in 1 dataset

RQ: which photos are used most often?+ No more manual checking

Let me upload 1 photo and find all similar photos RQ: how did the meaning of the photo change over time?+ No dependency of words

Applicable for other research questions:Show me all newspapers that contain the photo of Troelstra
