Fairchild HDR dataset网站提供了100余张HDR图像，但是没有提供打包下载，采用如下方法批量下载：
首先用wget下载整个网页：

wget -c -r -np -k -L -p http://rit-mcsl.org/fairchild//HDRPS/HDRthumbs.html

然后在下载目录下有一个Thumbs文件夹，里面的图像是HDR图像压缩后LDR图像，利用Matlab提取所有图像的文件名，更改文件的后缀，得到下载链接（所有的HDR文件都在http://www.cis.rit.edu/fairchild/HDRPS/EXRs/）下

files = dir('./*.jpg');
for i=1:1:length(files)
    [file_path,file_name,file_ext] = fileparts(files(i).name);
    name = strcat(file_name,'.exr');
    downloadLink = strcat('http://www.cis.rit.edu/fairchild/HDRPS/EXRs/',name,'\n');
    fprintf(downloadLink)
end

得到如下下载链接，并且保存在link.txt文件中：
