it's a DSLR from Nikon w/24MP
Nikon D3200
Has anyone used it , or can weigh in to how much of an impact it'd have on scanning in general and OCR in particular.

Re: impact of Nikon D3200
do u own this camera? even if u use your smartphone is good. anything more than 12 mp is enough
Re: impact of Nikon D3200
When imaging typical book pages smartphone megapixels might well be sufficient, but more generally the MP required will depend of other factors including:
o The final image quality required, only reasonable quality images, or high-quality images accepting that filesizes will be larger;
o The content of the pages to be imaged, whether only text or also containing images, and if so the resolution required to reproduce the detail in the images;
o How the images captured will be processed, text images to be processed using Adobe Acrobat's vectorisation output option do not require high DPI values, which may in fact noticeably slow processing without producing better quality text;
o The size of the pages to be imaged, clearly pages that are significantly larger than normal book pages are likely to need more pixels to produce good quality images. Newspaper pages being archived, for example!
Anyway, the question was whether anyone has experience of the Nikon D3200?

--ok download abbyfinereader 12 the pirate version the reason is because from the engines the final ocr pdf , djvu has smaller and better results rather than other versions.cday wrote: ↑09 Dec 2023, 07:42 When imaging typical book pages smartphone megapixels might well be sufficient, but more generally the MP required will depend of other factors including:

there u drag n drop images and there is a command like edit image >> resolution >> detect optical resolution . if the dpi are more than 300 the results are the same since u are from uk and u read english this is enough.
- it depends about what u scan what size is the image u capture but again the rule for dpi is the same , u can also rescale the final output with scantailor advanced or experimental versiono The content of the pages to be imaged, whether only text or also containing images, and if so the resolution required to reproduce the detail in the images;
- it depends what results u want is english the language u wanna capture because is extemely good the ocr rahter than other languages.o How the images captured will be processed, text images to be processed using Adobe Acrobat's vectorisation output option do not require high DPI values, which may in fact noticeably slow processing without producing better quality text;
- yes probably smartphone is not enough for newspaper there are more things like how good the focus of the camera is and if the text look sharp enough .o The size of the pages to be imaged, clearly pages that are significantly larger than normal book pages are likely to need more pixels to produce good quality images. Newspaper pages being archived, for example!
i tent to believe u have this camera so test it . check this video about some rules .build a cheap scanner like this and test your smartphone and the cameraAnyway, the question was whether anyone has experience of the Nikon D3200?
